Samples taken before and after secondary refining in the ladle and after degassing were compared with samples taken similarly from a heat including the addition of a calcium carbide (CaC 2) slag modifier. The amount, size distribution, and composition of non-metallic inclusions, as well as the slag compositions of both heats, were determined.
Fluorspar CaF2 Uses. However, the use of Fluorspar CaF2 as a slag agent for steel-making converters has certain limitations. On the one hand, the fluorine in fluorite will seriously erode the lining of the converter, resulting in a reduction in the life of the converter, pollution of the air, and increased consumption of steel materials.
