REHEATING MOLTEN STEEL BY ALUMINIUM-IRON OXIDE ADDITIVE

摘要

A method of reheating molten steel, which comprises, adding to the molten steel, a compressed material which includes aluminium and ferrous material containing iron oxide in which the ratio of aluminium to ferrous material is substantially not in the stoichiometric range. The aluminium is subsequently permitted to undergo exothermic oxidation. The aluminium and ferrous material are present in a range of preferably 40-95% Al to 5-60% Fe-oxide.
