Metallurgical cored wire uses steel strip as its outer shell, filled with powdered materials such as silicon-calcium and ferroalloys, and has a circular or rectangular cross-section.
In the steelmaking process, the cored wire is injected at high speed into the deep part of the molten steel by a wire feeder, achieving the following functions: Precisely controlling the amount of alloying elements added, improving the utilization rate of deoxidizers such as aluminum and calcium, and reducing air absorption in the molten steel.
It modifies non-metallic inclusions, improves the fluidity of molten steel, and prevents nozzle blockage during continuous casting.
