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 powder material is metal calcium and pure iron powder, and in order to prevent oxidation of metal calcium in the air, our Chinese principal has been the first enterprise to perform blending of materials and processing of this product under vacuum condition, in which the affinity of calcium with oxygen and sulfur elements is considerably huge in both cases, able for de-oxidation and de-sulfurization of molten steel. 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.
