| Abstract: | Based on the laboratory results the industrial test of deoxidation of molten steel was done on 150 t with ferroalloy containing barium ladle furnace and vacuum degassing equipment. Ferroalloys, such as SiAlBaCa and FeSiAl, and aluminum were used. The experimental results show that in molten steel deoxidized with the ferroal- loy containing barium, the deoxidation products are easier to coagulate and remove, then the content of oxygen is lower and small inclusions of spherical shape are distributed uniformly in the steel. |
