A process for the metallurgical treatment of molten crude metal, in particular molten crude steel in a ladle

摘要

In a process for the metallurgical treatment of molten crude metal, in particular of molten crude steel, in a ladle, a granular polymeric material, in particular at least one polyolefin such as polyethylene or polypropylene, is added to the ladle during the tapping of the crude metal, in order to cover heat losses and to create reducing conditions in the ladle atmosphere and in the furnace slag running along.
