Calcium Silicon Specifications
Application
Calcium Silicon is
a potent deoxidizer and desulfurizer utilized in the production of high
grade steels. Although Silicon itself is a powerful
deoxidizer, Calcium is by far more powerful. In addition, Calcium Silicon
is used to control the shape, size and distribution of oxide and sulfide
inclusions improving fluidity, machinability, ductility, and impact properties
of the final product.
Calcium Silicon is
also utilized in combination with Barium. The Barium increases the
density and reduces the vapor pressure of the alloy, thereby improving
efficiency. In cast irons it is used mainly by Pipe Shops for the purpose
of coating the inside of each mono cast machine.
Calcium Silicon can
be obtained in lump or powder form. The most widely used method for
intergrated steel applications is in the form of cored wire. This is
mainly because calcium has a low density and high reactivity in the
ladle making it difficult to introduce and retain in the melt. Cored
wire eliminates these variables.
