Conditional final-carbon adjustment after AOD tapping
Do not add a carbon raiser directly during AOD oxidative decarburization; carbon introduced by high-carbon ferroalloys belongs to the ferroalloy chemistry balance.
Confirm the process position before method and quantity calculations; an application relationship for one furnace or material must not be copied to another.

03 Addition point
Preferably added into the tapping stream after slag control or when the ladle contains about one-quarter to one-third of its steel; LF requires adequate dissolution time and a suitable low-oxidising slag
A steelmaking silicon source made principally from verified ferrosilicon fines by batching, binding, briquetting and curing or drying. After finished-product chemistry, effective silicon, moisture, strength and plant recovery are validated, it may be used for tapping deoxidation, silicon alloying and selected slag-reduction duties; it is not silicon-slag briquette, silicon-carbon briquette or lump ferrosilicon.
Used for technically reviewed deoxidation, calcium treatment and inclusion control in steelmaking and steel foundries; performance depends on grade, deoxidation state, sulfur, feed form and process stage.
A silicon-and-aluminium composite direction for deoxidation and chemistry adjustment in reviewed steelmaking and cast-steel practices; Si/Al ratio, residuals and timing must match the target grade.
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.

Depending on the confirmed SKU, it may be a smelted material or an agglomerated composite; after process review it may support combined Si/C adjustment, deoxidation practice or heat-balance trials. Phase constitution, chemistry, residuals, sizing, recovery and addition practice must be confirmed by the formal TDS, lot COA and plant trial.

A cored-wire family with a metallic-calcium core and steel sheath for controlled calcium treatment of reviewed steel melts. It is not interchangeable with calcium-silicon or composite-calcium cored wire; calcium purity, core construction, effective Ca per metre, diameter and plant recovery must be fixed in the formal SKU/TDS and lot COA.

A ferroboron-core wire for micro-boron alloying. It applies only to steel grades with a defined effective-boron window; total/acid-soluble B, N, O, Ti and Al must be confirmed, and the fed amount cannot be equated directly with hardenability or mechanical properties.
A powder-core wire for carburising reviewed steel melts. Carbon source, fixed carbon, ash, S, N, volatiles, moisture, core sizing and plant recovery jointly determine suitability; it is not interchangeable with bulk recarburiser or welding flux-cored wire.
A cored wire for controlled sulfur addition or resulfurisation in defined processes such as free-machining steel; it is not a general refining or purification product. Core form, target S, Mn/S relationship, steel oxygen state, fumes and fire controls must be confirmed.
A cored-wire family using a ferromanganese core for controlled manganese addition in steelmaking. High-, medium- and low-carbon ferromanganese grades are not interchangeable; Mn/C/Si/P/S, core sizing, core mass per metre and target recovery must be fixed in the SKU/TDS.
A ferrosilicon-core wire for steel deoxidation or silicon alloying. Ordinary FeSi core and cast-iron inoculant core containing active elements such as Ba, Sr, Zr or Ce are not the same specification and require separate SKUs and TDSs.
A candidate wire product for steel deoxidation or aluminium adjustment. 'Aluminium-core cored wire' may refer to steel-sheathed aluminium powder, a steel-covered aluminium core or solid aluminium wire; these have different construction and metering bases, so core construction, Al purity and effective Al per metre must be fixed first.
Rare-earth cored wire is a family name that still requires its core carrier to be specified. Ce/La misch metal, rare-earth ferrosilicon and other carriers cannot share one specification; selection requires the steel grade, O/S state, target residual RE and inclusion route.
A custom cored-wire family with Si, Ca and Mn as principal core indicators. It may serve reviewed steel composite addition or a specific cast-iron inoculation practice, but these uses cannot be promised under one generic specification; formula, industry and validation method must be fixed.
Composite calcium cored wire is a custom family using two or more calcium-bearing carriers, functional components or a defined layered construction. Single metallic-calcium, calcium-silicon and dedicated calcium-aluminium cores belong to their own product pages; CaFe and other confirmed multi-component or layered systems require their own formal TDS.
A custom cored-wire system with Si, Ca and Al as principal core indicators. Combined deoxidation and calcium treatment may be evaluated after chemistry and steel grade are confirmed, but online data for neighbouring CaAl, SiAlBaCa or SiCaBaAl products must not be copied.

A steel-treatment cored-wire family with Ca and Al as principal core indicators, potentially using a confirmed alloy-rod/solid, granule or powder-core construction. It supports process-reviewed combined Ca/Al addition or calcium treatment; core construction, Ca/Al, residuals, effective Ca/Al per metre, diameter and plant recovery must be fixed by the formal SKU, TDS and lot COA.

A dedicated slag-treatment family used to lower ladle top-slag oxidation, potentially aluminium-based or another verified system; its target is the slag, not a replacement for steel-bath deoxidation practice.
A dedicated flux family continuously added to the mould surface for coordinated coverage, lubrication, heat transfer and inclusion absorption; selection must match steel grade, section, casting speed and mould heat flux.
A covering-powder family used to insulate tundish steel, isolate air and—depending on formulation—assist inclusion absorption; acidic, basic or dual-layer systems must match steel grade and refractories.
A dedicated starter-flux family used to establish early coverage and initial liquid-slag conditions during casting start, potentially with a verified exothermic system; it is not automatically replaceable by regular mould flux.
A granular refractory family filling the ladle upper-nozzle and well-block region to support ladle free opening; mineral system, size distribution, sintering behaviour and ladle cycle require coordinated selection.

High-carbon silicon is a market term that may refer to a smelted alloy, furnace-bottom recovered and sorted material, or a formed blend of silicon- and carbon-bearing fines. An inquiry must first establish the actual production route, phases, total Si/C, residuals, form and addition point.
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.
