Calcium-based cored wire remains in strong demand worldwide, with approximately 70% of ferroalloy manufacturers’ output supplied to steelmakers. As a leading alloy producer in China, Hongshun Alloy has developed a comprehensive range of calcium cored wire products tailored for ladle refining and out-of-furnace applications. Our line includes pure calcium cored wire, silicon calcium cored wire, iron calcium cored wire, and calcium magnesium cored wire—all recognized as industry-standard solutions for modern steelmaking.
Calcium exhibits a high affinity for oxygen, making it highly effective in removing oxygen molecules from molten steel. This deoxidation step is critical in steel production. Thanks to its chemical properties, calcium serves as the core component in composite deoxidizers. When combined with other elements, it forms multi-functional deoxidizers that improve fluidity, prevent clogging in ladles and tundishes, and eliminate nozzle blockage issues.
Using calcium in cored wire form significantly enhances its performance. The wire feeding method extends reaction time, increases calcium yield, and ensures efficient impurity removal—resulting in cleaner, higher-quality steel.
Composite deoxidizers containing calcium improve the efficiency of other deoxidizing elements such as aluminum. They lower the concentrations of Ca, Al, and O in molten steel, boost purity, and reduce overall deoxidizer consumption. This means greater deoxidation per unit of material used.
Even without changing the valence state of the deoxidizing elements, the reaction frequency rises. Aluminum’s deoxidation capability is enhanced, while calcium consumption drops. This synergy makes the process more economical and effective. By selecting the appropriate cored wire composition, steelmakers achieve deeper deoxidation with less aluminum and calcium—maximizing cost efficiency and metallurgical outcomes.
In Ca-Al deoxidation practices, calcium acts as an accelerator, a cost reducer, and an inclusion modifier. It helps normalize production operations, elevates steel quality, and achieves lower oxygen levels. Thus, calcium is indispensable in steel refining.
Long-term industrial experience confirms that well-designed composite deoxidizers deliver consistent results. For different steel grades, adjusting the deoxidizer composition based on specific needs remains key to optimal performance.
