Calcium, as limestone, has always been a basic ingredient in iron and steelmaking. Its uses as a fluxing agent are well known. Treatment of liquid steel with calcium has become an important means of deoxidation and, more importantly, desulfurization to previously unthinkable levels. Equally significant is the now routine use of calcium to control the shape, size and distribution of oxide and sulfide inclusions. Benefits directly attributable to calcium treatment include greater fluidity, simplified continuous casting and improved cleanliness, machinability, ductility and impact strength in the final product. Calcium silicon, containing 28- 35% Ca, 60- 65% Si and 6% Fe, is the most co mm only used addition agent. It may contain up to 1 % C and 1. 5% Al. Availability all sizes
