Sažetak
Considering the specifics of steel production at the modern metallurgical plant, it should be noted that the main sources of steel pollution with nonmetallic inclusions in a teeming ladle are furnace slag, ladle lining and deoxidation products (alloying). Summarizing the information on the operation of the BOF lining, it was defined that the bottom part is destroyed 2 times faster than the walls on any kinds of applied lining. The average rate of destruction of the magnesia-carbon lining is 1.22 mm per melt, and the lining of heat-resistant concrete is 1.34 mm per melt. By engineering calculations it is determined that the maximum weight of nonmetallic inclusions entering steel due to the destruction of the lining is 0.92 kg/t of steel for magnesia- carbon refractories and 1.07 kg/t of steel for heat-resistant concrete.
