The calcium iron cored wire functions as the deoxidizer and the desulfurizer in the process of steel-smelting production, mainly applied to cold heading steel, pipe line steel, and other low-silicon steel types. Its core power material is metal calcium and pure iron powder. Its deoxidized outcome – CaO is also mingled and combined with Al2O3 system in the liquid steel to generate 7Al2O3.12CaO sinter of low-melting point, thus to avoid the effect of nozzle blockage arising from condensation of casting nozzle mingled with Al2O3 system, so as to ensure a smooth continuous casting production. The desulfurized outcome floats upwards very easily to be removed, so as to enhance the plasticity and tenacity of steel.

Application
Deoxidation: Calcium is a powerful deoxidizer. It reacts with oxygen and sulfur in the molten metal to form stable oxides and sulfides, which float to the surface and can be easily removed.
Desulfurization: The addition of calcium can help in reducing the sulfur content of the steel. Sulfur is another impurity that can negatively impact the quality of the final steel product.
Modifying Inclusions: The inclusion of calcium can modify and refine non-metallic inclusions in the steel, which improves its mechanical properties.
Controlled Inoculation: The introduction of calcium can also serve as an inoculant, promoting the formation of specific microstructures in the steel, depending on the desired properties.
Stabilizing and Controlling the Steel Chemistry: The controlled addition of calcium and iron helps in achieving the desired chemical composition of the steel.
