Silicon Calcium 6030 As Deoxidizer For Steelmaking
Calcium silicate, not called calcium silicate, contains 22 to 35% calcium and 60 to 65% silicon. YB 525-65 stipulates a calcium content of not less than 31%, 28% and 24%, respectively. Mainly used as a inoculant for cast iron.
Descrizione
Calcium silicon produces a strong exothermic effect when added to molten steel. Calcium turns into calcium vapor in molten steel, which has a stirring effect on molten steel and is beneficial to the floating of non-metallic inclusions. After the silicon-calcium alloy is deoxidized, non-metallic inclusions with larger particles and easy to float are produced, and the shape and properties of non-metallic inclusions are also changed. Therefore, silicon-calcium alloy is used to produce clean steel, high-quality steel with low oxygen and sulfur content, and special performance steel with extremely low oxygen and sulfur content.
