Method For Increasing The Scrap Melting Capability Of Bottom Blown Processes
US Patent:
4201572, May 6, 1980
Filed:
Aug 2, 1978
Appl. No.:
5/930441
Inventors:
Frank Slamar - Pittsburgh PA
Assignee:
United States Steel Corporation - Pittsburgh PA
International Classification:
C21C 534
US Classification:
75 60
Abstract:
In the bottom blown process for the refining of molten steel, additional heat is generated for melting greater amounts of scrap, by injecting at least one secondary stream of an oxygen-containing gas to the space above the molten metal bath so as to combust the CO and H. sub. 2 evolving therefrom. The excess heat so generated is absorbed both by the bath and the furnace lining, causing overheating and rapid deterioration of the lining. For a given quantum of heat so generated the ability of the molten metal to absorb a greater portion of that heat and thereby maintain the temperature of the furnace lining within the practical limits has been found to depend to a significant extent on the design of the furnace itself. The invention is directed to conducting the refining process in vessels which provide, for a given bath capacity, greater top surface areas than has heretofore been employed.
