Silicon-Calcium Alloy Cored Wire
The Silicon-Calcium Alloy Cored Wire functions as De-oxidiser and De-sulfurizer in the process of steel-smelting, mainly applied to Reinforced Bar Steel, Plain Carbon Killed Steel, and other steel types of relatively high silicon content. Its core powder material is Silicon-Calcium alloy powder. The affinity of silicon and calcium elements in the silicon-calcium alloy with oxygen is considerably huge, able for final deoxidation effective to liquid steel , and at the same time its one of the deoxygenated outcomes – CaO is mingled and combined with Al2O3 system in molten 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 line, so as to ensure a smooth continuous casting production. Moreover the calcium element is also able to remove the harmful elemental sulfur in the liquid steel, and the desulfurized outcome floats upwards very easily to be removed, so as to enhance the plasticity and tenacity of steel.
