2. Silicon calcium cored wire is an additive in steel making, which is helpful to adjust and control the content of easily oxidized elements and trace elements to greatly improve the alloy yield, reduce the smelting cost, shorten the smelting time, precise control ingredient. In the steel-making process, the rational use of silicon-calcium ...It is the silicon calcium core wire we often say. Calcium has a low density in the ladle and is highly reactive, so it is difficult to introduce and keep in the melt. The core wire eliminates these variables. Calcium silicon manufacturing process. 1. High-content silicon calcium alloy products, mainly produced by electrode furnace.
