Silicon-calcium-aluminium cored wire

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.

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 is

What it does

Combined deoxidation and calcium-treatment review after custom chemistry confirmation
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

Actual formula differences change deoxidation, inclusions and nozzle behaviour; complete inclusion liquefaction or open nozzles cannot be guaranteed

SELECTION BOUNDARY

Start with the selection boundary

Silicon-calcium-aluminium cored wire must specify Si, Ca and Al as principal indicators. It is not calcium-aluminium cored wire without Si as a principal indicator, pure-calcium cored wire or aluminium-core wire. Online parameters for neighbouring CaAl, SiAlBaCa or SiCaBaAl products must not be reused as this specification.

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

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

SELECTION AND COMPARISON

Compare specification directions by indicators and operating conditions

Supply specifications, packaging, lead time and quality documents are subject to the formal quotation and order confirmation.

01Specification direction

Silicon-calcium-aluminium cored wire

Compare the key indicators below, then confirm grade, guaranteed values, sizing and packing against the operating conditions.

Key indicators: Si / Ca / AlSteel sheath / diameter / g/mCore sizing / moisture / uniformity
Size and form: Confirm against the addition method, equipment and order requirements
Packaging: Confirm in the quotation and order

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 a defined Si/Ca/Al formula, grade, O/S and target inclusion route

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.

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 a defined Si/Ca/Al formula, grade, O/S and target inclusion route
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

Combined deoxidation and calcium-treatment review after custom chemistry confirmation

Limits and risks

Actual formula differences change deoxidation, inclusions and nozzle behaviour; complete inclusion liquefaction or open nozzles cannot be guaranteed

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

Use industry references to understand, then order documents to confirm

Supply specifications, packaging, lead time and quality documents are subject to the formal quotation and order confirmation.

DOCUMENTS & MEDIA

Images, TDS, SDS and COA

Document availability depends on the product, lot, destination market and order agreement.

TDS

Confirms product identity, guaranteed indicators, sizing, form and packing.

SDS / PSI

Confirms storage, handling, protection and market-specific safety information.

COA

Links a specific lot to test items, results, methods and issue information.
