Calcium in calcium-silicon alloys:
Calcium is an indispensable element in steel making. Its main purpose is to improve the fluidity of the steel and to increase the strength and cutting properties of the finished steel. The use of Calcium-Silicon alloys prevents clogging of the live opening and allows better handling of impurities in the molten steel. Drainage improves the properties of the finished steel.
Other uses of calcium-silicon alloys:
Calcium-silicon alloys are also used to produce high quality and speciality steel products. Calcium-silicon alloys are also used as heating agents, and they are often used in converter smelting.
