A LINING PROTECTION METHOD FOR CONVERTERS AND OTHER STEEL MELTING ASSEMBLIES WHICH USE TOP BLOWING THROUGH A WATERCOOLED LANCE INSULATED FROM METALWORKS AND GROUND

摘要

Usage: h ferrous metallurgy for protecting the lining of converters, and other steel assemblies. The essence of the invention is that when approaching electrical current to the conductive lining from one of the poles of the source d.c. podyus other DC source connected to the lance, and during purging electric current is passed between the tuyere and the refractory. The surface of the lance coated with a refractory material with a resistivity of 100 ohm-m YU9. Table 2. 1 pr.
