METHOD OF OPERATING ELECTRIC FURNACE FOR PRODUCING SYNTHETIC SLAG Russian patent published in 1997 - IPC

Abstract RU 2092575 C1

FIELD: metallurgical industry. SUBSTANCE: this is used in processing steel. According to method, charge is loaded into bath of electric furnace lined with carbonic blocks, charge is melted, synthetic slag is melted out, and synthetic slag is periodically tapped from furnace. Charge contains oxides of aluminium, calcium, silicon, chrome, iron, and titanium. At start of furnace operation, it is loaded with charge containing 10-20% of titanium oxide. After melting out of synthetic slag in amount of 10-30 t per 1 t of working capacity of bath, content of titanium oxide in loaded charge is reduced to 0.8-1.2%. EFFECT: high efficiency. 1 tbl
