What it is
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.

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
- Steel deoxidation, silicon adjustment and separately formulated inoculation
- Control addition point, depth and sequence through wire feeding
- Close the loop against the actual core, wire, equipment and lot
Where it fits
- Ladle-treatment stage after steel analysis and deoxidation conditions are established
Boundary not to miss
- Ordinary ferrosilicon wire does not automatically replace inoculant wire; incorrect active elements, core sizing or addition point can cause off-target deoxidation or structure
SELECTION BOUNDARY
Start with the selection boundary
A cored-wire product name is not a complete supply specification. The formal SKU/TDS must fix core chemistry and carrier, sizing/moisture, diameter and tolerance, steel-strip material/thickness/seam, core mass per metre and uniformity, joints, coil mass, pack, SDS/PSI and lot COA; third-party example data are not Jinsheng guarantees.
PRODUCT MANUFACTURING
Product manufacturing process
Cored wire is generally made through reviewed core preparation, sizing and moisture control, cold-rolled-strip forming, metered filling, seaming, coiling and inspection. This is a general industry illustration, not Jinsheng's own line or a named supplier process.
- 01Verify core identity, chemistry and safety documents
- 02Control core sizing, moisture and uniformity
- 03Form the steel strip, meter the core and close the seam
- 04Inspect diameter, core mass per metre, joints and leakage
- 05Coil, identify, sample and moisture-protect the pack
SPECIFICATIONS & PACKAGING
Grades, specifications, indicators and packaging
The specification must separate core chemistry from calculated whole-wire chemistry and define sizing/moisture, diameter and tolerance, strip material/thickness/seam, core mass per metre and variation, coil mass, joints, pack, TDS, SDS/PSI and lot COA together.
- 01Fix the formal core grade, carrier and test method
- 02Confirm sizing, moisture and core mass per metre
- 03Confirm diameter, strip, seam and joints
- 04Confirm coil, pack, label and lot documents
GRADES & SPECIFICATIONS

ORDER SPECIFICATION CONFIRMATION
What must be confirmed before this becomes an order specification
Supply specifications, packaging, lead time and quality documents are subject to the formal quotation and order confirmation.
- 01Confirm the product, grade, application and supply scope
- 02Fix guaranteed chemistry, sizing, form and packing in the quotation and order
- 03Agree sampling, test methods, acceptance rules and lot COA fields
- 04Confirm the required TDS, SDS/PSI, labels and delivery documents

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.
Steelmaking plants
Ladle-treatment stage after steel analysis and deoxidation conditions are established
- Furnace / equipment
- BOF, EAF, LF/VD/VOD ladle refining and pre-casting treatment equipment
- Material / output
- Steel with defined FeSi grade, residuals, core sizing and target Si
APPLICATION METHOD
Application method and effect validation
Before field use, confirm melt grade and initial chemistry, target net increase, temperature, slag, feeder, addition point, core mass per metre and historical recovery; trial-feed and resample before fixing speed, depth, total length and stop criteria.
- 01Confirm melt, target and prohibited conditions
- 02Make the mass balance from measured chemistry and core mass per metre
- 03Check the feeder and set the trial-feeding window
- 04Feed under the process card and control the reaction
- 05Resample, verify and confirm stop criteria
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
Steelmaking plants
Ladle-treatment stage after steel analysis and deoxidation conditions are established
- Furnace / equipment
- BOF, EAF, LF/VD/VOD ladle refining and pre-casting treatment equipment
- Material / output
- Steel with defined FeSi grade, residuals, core sizing and target Si
- Method
- First confirm the formal core grade, chemistry, sizing/moisture, diameter, steel strip, core mass per metre and joints; then establish speed, depth and stop criteria from melt analysis, temperature, feeder and a trial-feeding plan.
- Quantity determination
- Calculate from initial melt value, target net increase, measured core chemistry, core mass per metre and plant recovery, then close by resampling; no fixed kg/t or m/s is published without furnace, grade and equipment context.
Expected effects
- Steel deoxidation, silicon adjustment and separately formulated inoculation
Limits and risks
- Ordinary ferrosilicon wire does not automatically replace inoculant wire; incorrect active elements, core sizing or addition point can cause off-target deoxidation or structure
STORAGE & SAFETY
Storage, handling and risk
- Keep dry, moisture-protected and rust-protected, preventing powder leakage, wire breakage and loose coils; inspect appearance, joints, identity and pack integrity before handling and feeding.
- The core may present dust, combustion, reactivity, fume or melt-splash risks; operate only under the actual SKU SDS/PSI, equipment procedure and destination rules.
This section does not replace the company's final SDS/PSI or the plant safety procedure.
REFERENCE AND ORDER BOUNDARY
