QUICK DECISION
Four answers before reading the technical detail
This section supports initial screening; final grade, addition and effects require operating conditions, formal documents and plant validation.
What it does
- Iron-melt pretreatment
- Preparation for downstream graphite treatment
- Formula and mechanism verification
Where it fits
- Post-melt pretreatment before nodularising, CGI treatment or inoculation
Boundary not to miss
- Unclear identity, sequence or formula can cause added slag, temperature loss, uncontrolled reaction, inclusions or off-target graphite structure
SELECTION BOUNDARY
Start with the selection boundary
Pretreatment agent is not a fixed chemical name and is not automatically a desulfuriser, inoculant, nodulariser or CGI treatment alloy. Obtain formula boundary, mechanism, sequence, SDS and lot COA before trials.
PRODUCT MANUFACTURING
Product manufacturing process
A cast-iron preconditioner may be a verified smelted alloy, compound granule or mechanically blended/agglomerated system; identity and route are supplier-specific. The general commercial flow is limited to feed and formula review, smelting or formulation by the declared route, sizing/homogeneity control, sampling, testing and packing. Furnace, binder or formula must not be inferred without manufacturer documents, and this page does not depict a Jinsheng-owned line.
- 01Cast-iron preconditioner must first be verified as a smelted alloy, compound granule or blended-agglomerated product, with the supplier's formal formula, carrier, feeds and use statement. Different routes must not share one quality basis.
- 02Confirm smelted-alloy, compound-granule or blended-agglomerated identity and formal formula documents
- 03Verify feeds, returns and binder/carrier materials and manufacture by the supplier-declared route
- 04Control homogeneity, form, sizing, fines, moisture, strength and cross-lot mixing
- 05Sample representatively and check chemistry, physical indicators, safety documents and pack traceability
SPECIFICATIONS & PACKAGING
Grades, specifications, indicators and packaging
Cast-iron preconditioner is a functional category, not one chemical grade. The supplier TDS, SDS/PSI, sample COA and purchase agreement must state smelted-alloy or formulated-product identity, carrier and all active/limiting elements, test methods, form, sizing, fines, moisture, strength, pack, addition stage and formula-change control. No fixed chemistry or performance value is assumed.
- 01The specification must fix all active/limiting elements, carrier, smelted/formulated identity, form, sizing, fines, moisture, strength, pack, test methods and formula-change control.
- 02Confirm the formal name, manufacturing route, target iron and process stage
- 03Fix the carrier, all active/limiting elements, residuals and corresponding test methods
- 04Confirm form, sizing, fines, moisture, agglomerate strength and within-lot homogeneity
- 05Confirm pack, label, TDS, SDS/PSI, lot COA and formula-change notification

INDUSTRY APPLICATION
Industry, furnace, material and addition point
Confirm the process position before method and quantity calculations; an application relationship for one furnace or material must not be copied to another.
Iron foundries
Post-melt pretreatment before nodularising, CGI treatment or inoculation
- Furnace / equipment
- Cupola, induction, duplex or a confirmed iron-treatment ladle
- Material / output
- Cast-iron melt with a defined base condition, treatment objective and downstream graphite-treatment route
APPLICATION METHOD
Application method and effect validation
Preconditioning must be reviewed with charge mix, base-iron chemistry, S/O condition, superheating and holding history, downstream nodularising/compacted-graphite/inoculation plan and target casting. Set a controlled trial from measured lot values and the site baseline, closing by thermal analysis, nucleation condition, chill, graphite, slag entrainment, defects and performance. No fixed kg/t or universal effect claim is published.
- 01Before furnace, tapping-stream or ladle preconditioning, review charge, base-iron S/O, thermal history, downstream nodularising/compacted-graphite/inoculation route and target casting.
- 02Confirm iron type, charge, base chemistry, S/O, thermal history and downstream treatment route
- 03Check the formal formula, lot COA, sizing and dry condition and set a controlled site comparison
- 04Add at the approved furnace, tapping-stream or ladle point and record temperature, time and downstream treatment
- 05Use thermal analysis, chill, graphite, slag entrainment, defects and performance to decide approval, correction or stop
- 06Use a controlled site comparison to validate thermal analysis, nucleation condition, chill, graphite, slag entrainment, defects and performance; no fixed kg/t or universal preconditioning effect is published.
PROBLEM AND SOLUTION
From operating objective to effect verification
Each application explains the role, method, quantity principle and risk boundary; the final proposal is confirmed against operating conditions and lot documents.
01
Iron foundries
Post-melt pretreatment before nodularising, CGI treatment or inoculation
- Furnace / equipment
- Cupola, induction, duplex or a confirmed iron-treatment ladle
- Material / output
- Cast-iron melt with a defined base condition, treatment objective and downstream graphite-treatment route
- Method
- Confirm actual product identity, mechanism, sizing and treatment sequence, then establish the practice through controlled trials; do not convert a commercial name directly into a fixed formula.
- Quantity determination
- Determine from base-iron analysis, treatment target, lot TDS and site trials; the website publishes no fixed chemistry, kg/t, recovery or performance promise.
Expected effects
- Supports stable downstream treatment conditions within a validated practice
Limits and risks
- Unclear identity, sequence or formula can cause added slag, temperature loss, uncontrolled reaction, inclusions or off-target graphite structure
STORAGE & SAFETY
Storage, handling and risk
- Keep dry and lot-segregated and prevent mix-ups; dust, fume and hot-metal charging controls must follow the SDS/PSI for the actual form and plant procedures.
- Without a formal SKU, TDS, SDS/PSI and lot COA, no chemistry, grade, sizing, pack, stock, dose, recovery or performance is promised.
This section does not replace the company's final SDS/PSI or the plant safety procedure.
