PROCESS & EQUIPMENT
Production routes and key equipment
Carbon material used directly in the cupola
Foundry coke for cupola melting↗Cupola fuel, burden support, reducing-atmosphere source and contributor to the iron carbon balanceSelect foundry coke by size, strength, reactivity, ash, sulfur and moisture; coke breeze cannot replace qualified foundry coke.
Cupola manganese adjustment
High-carbon ferromanganese↗Cupola charge Mn adjustment from charge Mn, S, target matrix and final-carbon budget
Cupola carbon-material boundary
A carbon raiser does not replace foundry cokeThe cupola carbon/sulfur balance is governed jointly by charge, foundry coke and furnace practice; other recarburizing routes require validation at a separate melting or holding node
Induction-furnace charge and iron carbon adjustment
Carbon raiser↗Use in stages to measured charge carbon, final-carbon target, addition timing and bath-stirring conditionsUse as the carbon-raiser route and selection-boundary overview, not as a single grade.
Columnar carburizer↗Use in stages to measured charge carbon, final-carbon target, addition timing and bath-stirring conditionsColumnar is a finished shape only; confirm feedstock, binder, strength, residuals and an induction-furnace absorption trial.
Spherical carburizer↗Use in stages to measured charge carbon, final-carbon target, addition timing and bath-stirring conditionsSpherical is a finished shape only; confirm feedstock, binder, strength, residuals and an induction-furnace absorption trial.

Induction-furnace manganese adjustment
High-carbon ferromanganese↗Mn adjustment after balancing pre-addition Mn/C/Si/P/S, returns and target microstructure
Induction-melting process boundary
Do not inherit EAF or cupola carbon materialsA conventional medium-frequency induction furnace does not use EAF foamy-slag injection carbon or graphite electrodes and does not treat foundry coke as its default charge carbon raiser
Cupola stage
Foundry coke for cupola melting↗Used only in the cupola-melting stage of the duplex lineSelect to the cupola burden, blast, melt rate and iron carbon balance.

Duplex-route manganese adjustment
High-carbon ferromanganese↗Conditional Mn adjustment in the induction or holding stage from cupola-output analysis
Duplex-stage boundary
Every carbon material must identify its use stageDo not merge cupola foundry coke and induction-furnace carbon raisers into one material described as applicable across the whole line
Adjacent upstream base-iron carbon control
These links identify upstream melting materials; they do not indicate direct carbon-raiser addition at the nodularization, compacted-graphite-treatment or inoculation node.

Molten-iron-treatment boundary
Silicon-magnesium inoculant↗Enter inoculation practice only when Mg level, designed duty and supplier TDS establish a low-Mg specialty inoculantIf the material is actually MgFeSi or RE-Mg-FeSi, select it as a nodulariser instead.
No direct carbon-raiser addition at the treatment nodeA carbon raiser cannot replace a nodularizer, compacted-graphite treatment alloy or inoculant
Graphite morphology is a microstructure outcomeSpheroidal or compacted graphite is not a product mapping for graphite powder added at this node
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.
01
01 Furnace / equipment
Cupola, induction and duplex melting
02 Material / output
Base iron for grey, ductile and CGI, plus alloyed cast iron
03 Addition point
In-furnace silicon correction or post-melt trimming
Can be managed as a reviewed silicon-barium inoculant for cast iron or as a compound steel deoxidizer; Ba/Si system, sizing, addition point and acceptance criteria must remain application-specific.

A cored-wire family with Si, Ca and Ba as principal core indicators, for formulation-confirmed cast-iron inoculation or dedicated steel treatment. Active elements, sizing, addition point and validation differ between the two uses and require separate SKUs.
A foundry treatment wire with a rare-earth magnesium ferrosilicon core. For reviewed ductile- or compacted-graphite-iron treatment, base-iron S, temperature, treatment ladle, target residual Mg, feeding practice and post-inoculation validation must be considered.
A composite-magnesium cored-wire family for cast-iron treatment, potentially using pure Mg, FeSiMg or another composite carrier. Mg carrier, RE/Ca/Ba, base-iron S, temperature, treatment ladle and fume control must be fixed before nodularizing or compacting use is evaluated.
A cored-wire family with a verified ferrosilicon-barium core in a steel sheath. Cast-iron inoculation is the primary review scenario; steel-treatment use requires a separate SKU and process record. Si, Ba, Fe and residual Al, Ca, C, P and S, core sizing, core mass per metre and wire construction must be fixed by the formal TDS and lot COA.

A column-shaped recarburizing material made from confirmed carbonaceous fines by blending, binding, extrusion or moulding, drying and screening. Columnar form is a supply shape only; the actual carbon source, heat-treatment route, dimensions, strength and furnace behaviour require a real SKU and furnace trial.
A spherical or near-spherical recarburizing material made from confirmed carbonaceous fines by blending, binding, agglomeration or briquetting, drying/curing and screening. Spherical appearance does not establish feedstock, graphitization level, grade or recovery.
A ferromanganese carbon grade used to adjust Mn while adding carbon in steelmaking, steel foundries and selected iron-foundry melting. The table gives standard-reference directions from GB/T 3795—2014 and public producer data, not Jinsheng lot guarantees.
