Introduction
Cored wires are vital tools in secondary metallurgy. However, with multiple types—such as CaSi, FeCa, CaFeAl, and Pure Ca wire—many buyers struggle to determine which product fits their process best.
This guide helps purchasing and technical teams make the right choice for different refining goals.
1. The Role of Cored Wire in Secondary Metallurgy
Cored wires precisely deliver alloying and refining agents into molten steel.
Benefits include:
• Controlled reaction depth
• High recovery rate
• Low material loss
• Uniform composition
2. Comparison of Common Cored Wire Types
Type Main Composition Function Typical Application
CaSi Ca 30%, Si 60% Deoxidation, inclusion control High-grade steel, bearing steel
FeCa Ca 30–35%, Fe balance Desulfurization, inclusion control Carbon steel, low alloy steel
CaFeAl Ca, Fe, Al Simultaneous deoxidation & desulfurization Stainless steel
Pure Ca wire Ca 98% Deep desulfurization, clogging prevention Ultra-low-sulfur steel
3. Key Factors to Consider When Purchasing
1. Steel grade and process route — Determine if desulfurization or inclusion control is the priority.
2. Wire diameter and feeding speed — Thicker wires for large ladles; thinner for precise control.
3. Quality of powder filling — Uniform filling ensures consistent wire weight and reaction.
4. Supplier’s technical service — Reliable support for on-site parameter optimization.
4. Common Problems and Solutions
Problem Possible Cause Solution
Poor Ca recovery Wire oxidized or injected too early Optimize feeding depth and wire quality
Ladle nozzle clogging Excess Al₂O₃ inclusions Use CaSi instead of pure Al deoxidation
Unstable chemical composition Uneven filling or moisture Choose vacuum-packed wires
