# Sand-cast austenitic manganese-steel crusher jaw-plate manufacture

## 1. Scope and Applicability

New complete replacement crusher jaw plates of declared austenitic manganese steel, sand-cast by electric melting, solution heat treated in an electrically heated furnace, water-quenched and finished to a controlled drawing in an unpainted supplied state. Include actual mould preparation, heat charge/chemistry, pour/shakeout, thermal processing, finishing, metallurgical/dimensional/net-mass acceptance and conditional protection. This narrower route within CPC44462 does not cover every mineral-machine part.

Exclude complete crushers, jawstocks/frames, cone mantles/concaves, screens, general cast stock, high-chromium white iron, martensitic/Q&T steel, ceramic or carbide inserts and other composite parts, painted/coated supply states, refurbished/repaired used liners, standalone pattern/tool manufacture, site installation, mineral throughput, use-phase work hardening/wear/replacement and end of life. Gas-fired or undeclared melting/heat routes need separate assessment.

The selected electrical and unpainted route is an applicability choice requiring actual foreground records, not a claim that every foundry follows it. Manufacturer references support sand casting, thermal control and fit/traceability context only. No universal alloy composition, melt yield, temperature/time/quench volume, part mass, hardness, service life or wear rate is adopted. Actual heat/BOM/recipe/acceptance and weighing originals remain required; scientific review is pending. Operating receipt-to-acceptance foreground is not complete cradle-to-gate without compatible verified upstream datasets.

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Manufacture a specified complete finished manganese-steel crusher jaw plate |
| How much | 1 kg accepted plate net mass; normalize per-unit collection by physically measured M |
| How well | Actual grade/heat metallurgy, drawing tooth/fit profile and producer/customer acceptance; equal mass is not equal fit, toughness or wear resistance |
| How long or cycle | One manufacturing and acceptance cycle; no crushed-tonne service, replacement interval or lifetime |
| reference_flow_link | finished_plate |

| Field | Value |
| --- | --- |
| Reference amount | 1 |
| Reference product flow | Accepted solution-treated austenitic manganese-steel crusher jaw plate |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |
| Reference unit group | Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` |
| Reference unit | kg |
| Required qualifiers | producer/foundry/site/period; part number/drawing revision, tooth profile, mounting/fit geometry and individual serial/batch/heat; actual steel grade and C/Mn/Cr/residual assay; furnace types, external charge versus internal gates/risers/returns, actual mould sand/binder recipe and reclamation; recorded casting/solution/quench cycle and metallurgy; actual finishing and unpainted complete state; controlled inspection/sampling and release; positive physically measured M kg, calibration/tare/uncertainty and packaging exclusion; material/water/energy/waste/species balances, causal allocation and upstream gaps |

One complete unit here means one accepted jaw plate, not a pair or a complete crusher. Declare qualifiers in dataset metadata or equivalent notes; missing qualifiers make reference incomplete. M includes the finished plate alone, excluding removable fasteners, insert hardware, fixtures and protection; do not use blank, charge, assembled crusher, catalogue or density-calculated mass.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| `reference_mass` | reference product | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | M = accepted net mass of one complete unit of the same configuration in kg; collect using cp_mass. |
| `mass_record_provenance` | cp_mass | Mass | kg | Complete unit in this protocol is one finished jaw plate of the same drawing/revision, grade and supplied state. Physically weigh each accepted plate on a suitable calibrated scale with measured fixture tare; retain heat/part identity, actual readout, calibration/uncertainty, date/operator and signed release. Same-configuration counts require actual accepted unit counts linked to these mass originals. Gates, risers, rejected castings, scale removed in treatment and machining chips are outside finished M. No assumed per-plate mass or catalogue weight conversion. |
| `energy_units` | each electricity row | Net calorific value | MJ | Use verified energy-unit conversion 1 kWh = 3.6 MJ. Preserve actual power provider/voltage and furnace, mould, pump, extraction and machining meters including standby. No assumed yield or rated power substitutes for measurement. |


## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Actual received external charge metals, mould ingredients, consumables and utilities |
| starting_condition_role | Receipt-to-accepted-jaw-plate operating foundry/manufacturing foreground |
| product_classification_scope | New complete replacement crusher jaw plates of declared austenitic manganese steel, sand-cast by electric melting, solution heat treated in an electrically heated furnace, water-quenched and finished to a controlled drawing in an unpainted supplied state. Include actual mould preparation, heat charge/chemistry, pour/shakeout, thermal processing, finishing, metallurgical/dimensional/net-mass acceptance and conditional protection. This narrower route within CPC44462 does not cover every mineral-machine part. |
| recursive_input_rule | No finished jaw plate as input to its own manufacture. Internal liquid metal/gates/risers/rejects and reclaimed sand are transfers; external received charge is separate. Purchased cast blanks replace contained melt/mould/casting scope and require a separately declared starting gate |
| upstream_dataset_requirement | Match metal grades/assays, external scrap state, sand/binder composition, refractory/abrasive supplied state, electricity and water boundaries, site/period and actual flow property/unit. Unmatched links remain gaps |
| disclosure | producer/foundry/site/period; part number/drawing revision, tooth profile, mounting/fit geometry and individual serial/batch/heat; actual steel grade and C/Mn/Cr/residual assay; furnace types, external charge versus internal gates/risers/returns, actual mould sand/binder recipe and reclamation; recorded casting/solution/quench cycle and metallurgy; actual finishing and unpainted complete state; controlled inspection/sampling and release; positive physically measured M kg, calibration/tare/uncertainty and packaging exclusion; material/water/energy/waste/species balances, causal allocation and upstream gaps |

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `boundary_manufacture` | all processes | Include actual forming moulds, electric melting/pouring, sand recovery, solution/quench, finishing and inspection with rework and outsourced gates. Declared long-lived furnaces, patterns, machine tools and factory infrastructure are excluded from core operating foreground; add any separately evidenced capital contribution transparently. Do not duplicate outsourced service and its contained resources. Installation, crushing and service wear lie outside. |  |
| `boundary_actual_exchanges` | complete actual heat route | Cards are starting exchanges requiring actual recipe/route applicability, not a complete universal bill. Add each actual binder constituent/catalyst/coating, flux/alloy, furnace atmosphere, tool/coolant, blast medium, NDT chemical, repair-weld consumable, filtered residue and measured species with exact identity when performed. Thermal/mechanical defects or fume cannot be assigned invented quantities. Record missing versus evidenced not_applicable; no complete LCI claim until actual heat/material/operation balances reconcile. |  |


## 6. Process Inventory Structure

### Process Map

| process_id | process_name | inclusion | inclusion_condition | role | quantitative_reference |
| --- | --- | --- | --- | --- | --- |
| `moulding` | Pattern-controlled sand mould preparation | required | Declared sand-cast jaw-plate route | foreground | one accepted same-configuration finished unit, normalized using M |
| `melting` | Electric melting and heat-specific alloy adjustment | required | Declared electric melt route, actual furnace type recorded | foreground | one accepted same-configuration finished unit, normalized using M |
| `casting` | Pouring, solidification and shakeout | required | Actual sand-cast plate heat and mould | foreground | one accepted same-configuration finished unit, normalized using M |
| `thermal` | Electric solution heat treatment and water quench | required | Declared austenitic manganese steel solution-treated delivery route | foreground | one accepted same-configuration finished unit, normalized using M |
| `finishing` | Drawing-controlled finishing and dimensional machining | required | Actual required finished-fit jaw plate | foreground | one accepted same-configuration finished unit, normalized using M |

| `packing` | Conditional factory-gate protection | conditional | Only actual shipped protection | foreground | one accepted same-configuration finished unit, normalized using M |

Moulds and alloy-adjusted molten metal meet at casting; actual cooled/shaken-out casting goes through solution treatment/quench and finishing to acceptance. Internal metal/sand recirculation stays within this map and is measured explicitly. Packaging is conditional. Every card needs actual recipe, supplied state and stage applicability.

### Process: Pattern-controlled sand mould preparation (`moulding`)

Prepare the actual part/revision pattern, mould cavity, feeding/gating and cores only when required. Record actual sand/binder recipe, reclaimed versus virgin supply, yield and reclamation. Quartz sand and sodium-silicate binder cards are specific conditional examples; no universal resin, binder concentration or sand ratio. Actual alternative ingredients must have separate physical identities.

## 7. Allocation and Co-product Handling

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `allocation_heat` | heat/batch and shared resources | Directly assign charge and mould/finishing jobs where possible. For shared heat metal, record chemistry-compatible total metal transfers, internal returns and accepted plate/reject inventories with actual attributable metal balance. Shared furnace/thermal/extraction resources use measured causal charge/load, furnace occupation and actual cycle: share = order driver / sum of covered order drivers. Preserve period, denominator, standby and sensitivity; never distribute by catalogue weight or assume uniform yield. |  |
| `allocation_returns` | internal metal/sand loops | Internal gates, risers, rejects, chips and reclaimed sand remain controlled internal transfers, with actual stock and losses; do not create a second purchase or avoided-virgin-material credit. Carry actual remelt/reclamation energy and wear. External charge and final waste transfers stay distinct. Rework and rejected production affect accepted-output denominator; no universal return fraction or recycled-content claim from input totals alone. |  |
| `allocation_coproduct` | saleable co-products and qualification | Trace each actual exported slag/scrap and destination once. Co-product status/allocation requires actual contractual, causal/economic evidence and sensitivity, not recyclability alone. Actual batch qualification tests are attributed to covered production with traced sampling scope/driver; destroyed test material is not accepted output. Independent R&D is separate; no assumed test frequency or tooling life. |  |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| `normalize_mass` | all inventory rows | q_ref = q_item / M; q_item = exchange amount per one accepted finished unit; q_ref = exchange amount per 1 kg reference flow. | q_item; M; cp_mass | q_ref |  |

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| `quality_mass` | cp_mass | Require mass_record_provenance actual calibrated physical finished-plate weighing, same drawing/grade/supply state and positive net M kg. Retain heat/part trace and measured tare; excludes gates/risers, rejects, chips, removed scale, fixtures and packaging. No melt charge, blank mass, density estimate or complete-crusher mass substitutes. Actual accepted counts must agree with mass/configuration originals. Missing originals requires scientific/data review. | actual part weighing/calibration/tare and signed release |
| `quality_identity` | all exchanges | Verify one chemical/physical exchange and actual supply grade/state. Ferromanganese is not silicomanganese or elemental manganese; graphite recarburizer is not coal or activated carbon; refractory brick/disc is not pure alumina; actual sand binder solution is not dry powder. Waste dust/sand/slag is not an elementary environmental emission. Preserve actual reference property/unit and phase/medium; unresolved identities stay precise. | supplier assay/recipe/SDS and public identity/unit originals |
| `quality_metallurgy` | cp_melting; cp_thermal; cp_acceptance | Trace part to heat charge chemistry, residuals and actual qualified solution/quench cycle. Retain furnace calibration/loading, temperature/time and transfer/quench records plus actual metallurgical/dimensional acceptance reports. Thermal logs alone do not establish austenitic condition; use producer-required examination with actual sampling/specification. No universal chemical range, hardness, magnetic-test criterion, carbide threshold or heat curve inferred. Repair weld or later thermal exposure requires actual qualified evidence, not an assumed equivalent condition. | actual heat/part chemical, thermal, metallurgical and release originals |
| `quality_balance` | metal, sand, water, energy and species | Reconcile external charge, internal circulation, accepted metal, rejects/returns, slag/scale/chips and actual inventory changes by heat/period; do not assume yield=1. Sand balance separates fresh make-up, reclaimed loops and final disposal. Water supply/recirculation/purge and evaporation need actual records, no automatic resource/wastewater equivalence. Quartz-air requires actual crystalline-quartz CAS14808-60-7 released fraction and medium; amorphous silica, total dust and captured residue are not substitutes. Other metal/oxide or combustion emissions require individual chemistry and actual evidence before adding identities. | actual heat/material/sand/water/species balances and transfers |
| `quality_coverage` | actual dataset and upstream links | Distinguish measured/calculated/missing/evidenced not_applicable. Audit actual whole process map, recipes and machining/inspection consumables beyond candidate cards, supplier boundaries, outsourced processing, capital exclusions, allocation and uncertainty. Verified compatible upstream links are needed for full cradle-to-gate. Contract checking does not establish factory data completion, performance validation or scientific approval. | actual complete heat/operation records and transparent gaps |


## 9. Validation Rules

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `validate_reference` | reference and finished_plate | Exact reference product name equals finished_plate output. Use actual positive M kg with cp_mass and normalize_mass. Blank candidate reference UUID registers that precise row in unresolved_flow_identities. Verify one complete accepted jaw plate, actual grade/profile/heat and unpainted gate, excluding other parts/protection. |  |
| `validate_basis` | all rows/protocols | Check ordered bilingual lawful lowercase row/rule/protocol IDs and actual projected references, per-unit q_item, M kg and same-configuration counts. Unit means one jaw plate throughout. Preserve real public Number/Area/Energy properties; compatible conversions require original metrology, never relabel as Mass. |  |
| `validate_route` | heat/mould/finish records | Require actual selected electric sand-cast solution/water-quench route, heat chemistry/mould recipe, part/heat tracing, actual finished metallurgy/fit and physical mass originals. Internal returns are not external purchases; spent sand and capture dust are not air releases. Missing records or unqualified repair/exposure requires review. |  |
| `validate_use` | dataset use | Disclose exact part/grade/heat/profile/gate, weighing/thermal/metallurgy originals, missing exchanges and unresolved identity/upstream gaps. Equal kg cannot prove equal wear life, impact toughness or crusher throughput. Candidate remains unpublished with scientific review pending. |  |


## 10. Published Dataset Profile

| Field | Value |
| --- | --- |
| dataset_role | secondary_dataset and background_dataset after actual data completion/review |
| downstream_use | Specified new crusher jaw-plate input to separately bounded machine assembly or replacement lifecycle |
| allowed_use | Manufacturing comparisons for matching grade, profile, heat-treated state and supply gate with actual mass and upstream links disclosed |
| excluded_use | Exclude complete crushers, jawstocks/frames, cone mantles/concaves, screens, general cast stock, high-chromium white iron, martensitic/Q&T steel, ceramic or carbide inserts and other composite parts, painted/coated supply states, refurbished/repaired used liners, standalone pattern/tool manufacture, site installation, mineral throughput, use-phase work hardening/wear/replacement and end of life. Gas-fired or undeclared melting/heat routes need separate assessment. |
| required_metadata | producer/foundry/site/period; part number/drawing revision, tooth profile, mounting/fit geometry and individual serial/batch/heat; actual steel grade and C/Mn/Cr/residual assay; furnace types, external charge versus internal gates/risers/returns, actual mould sand/binder recipe and reclamation; recorded casting/solution/quench cycle and metallurgy; actual finishing and unpainted complete state; controlled inspection/sampling and release; positive physically measured M kg, calibration/tare/uncertainty and packaging exclusion; material/water/energy/waste/species balances, causal allocation and upstream gaps |
| required_quality_disclosure | Measured/calculated/missing records, actual net weighing/heat/metallurgy/fit originals, identity and upstream gaps, capital exclusion, allocation and uncertainty; candidate scientific review pending |
| update_trigger | Part/drawing/tooth/fit profile, grade/charge/binder, furnace/casting/solution/quench route, repair/finish/coat state, physical mass/acceptance, site or upstream change |
