Silicon Calcium Barium

Silicon-calcium-barium Alloy, CALBALLOY （BaSi series） Inoculants Usage and Function of

Silicon-calcium-barium Alloy , AS inoculants.

Silicon-calcium-barium alloy is the new high-efficiency complex alloy in barium ally. It is the deoxidizing 

addition and desulfurizing agent as well as dephosphorizing agent in the steel-making. Thus, it acts as the 

inoculant and alterative during foundry. Barium can reduce the vapor tension of calcium in the steel-makingtemperature and increase the solubility of calcium in steel liquid. Compared with the silicon calcium alloy, if adding silicon-calcium-barium alloy into the steel residue as the calcium resource, when the calcium 

quantity is the half of the silicon-calcium alloy, the content of calcium in steel liquid is about two times of   the residue with silicon calcium alloy and the stability of calcium is improved remarkably. Thus, barium in   steel residue can protect the calcium and reduce the volatilization and oxidation of calcium. So, the purpose of calcium treatment in steel liquid can be achieved.
