What Is Cored Wire and What Is It Used For in Steelmaking?
Core filling ratio: 15%–50% alloy powder (customized by grade)
Function: precise alloy element injection into molten steel
Key benefit: high recovery rate + low oxidation loss
Common types: CaFe, CaSi, FeTi, FeV, pure Ca cored wire
Industrial use: steel refining, inclusion control, desulfurization
What Is Cored Wire?
Cored wire is a composite metallurgical material consisting of a thin steel sheath filled with alloy powders such as calcium, silicon, titanium, vanadium, or rare earth elements.
It is injected directly into molten steel using a wire feeding machine, allowing precise control of alloy composition during steelmaking and secondary refining processes.

Why Is Cored Wire Used in Steelmaking?
How Does Cored Wire Work in Molten Steel?
Cored wire is injected deep into molten steel, where the outer steel sheath melts and releases alloy powders directly into the liquid metal.
This ensures:
minimal oxidation loss
deep penetration into melt
precise alloy control
Why Is Cored Wire Better Than Bulk Alloy Addition?
Compared to traditional ferroalloy dumping, cored wire provides:
higher element recovery rate
lower temperature loss
better composition accuracy
reduced slag formation
This is critical for modern steel refining systems.
Why Is It Important for Steel Quality?
Cored wire helps control:
sulfur and oxygen levels
inclusion modification
microstructure refinement
This directly improves steel cleanliness and mechanical performance.
Product Grade Comparison
Calcium Cored Wire vs Silicon Calcium Wire
Calcium cored wire is mainly used for inclusion modification, while silicon calcium wire is used for deoxidation and desulfurization.
FeTi Cored Wire vs FeV Cored Wire
FeTi improves grain refinement, while FeV significantly enhances steel strength and hardness.
Pure Calcium Cored Wire vs CaFe Cored Wire
Pure calcium wire provides stronger refining effects, while CaFe wire offers more stable feeding and easier handling.
What Are the Applications of Cored Wire?
Why Is It Used in Steel Refining?
It is widely used in secondary metallurgy to fine-tune steel composition.
Where Is It Used in Industry?
ladle furnace (LF)
vacuum degassing (VD/VOD)
continuous casting
alloy steel production
What Does It Improve in Steel?
toughness and ductility
cleanliness of steel
mechanical strength
inclusion shape control
Summary
Cored wire is an advanced metallurgical feeding material used in steelmaking to accurately add alloy elements into molten steel. It improves alloy efficiency, reduces oxidation loss, and ensures high-quality steel production in modern refining processes.
