摘要

The manufacture of stainless steel begins with the production of molten stainless steel in electric furnaces. The molten stainless steel is refined in an argon-oxygen-decarburization (AOD) furnace or a similar refining furnace. The first solid form of the steel produced in these facilities is either an ingot, bloom, billet, or slab. Ingots are rolled or forged into blooms, billets, or slabs. Slabs are used to produce flat-rolled products, including sheet, strip, I and plate, while blooms and billets are used to produce long products, including bars and light shapes, wire rod, and seamless tubular products. AOD refining facilities are usually not utilized in the production of other grades of steel. Therefore, stainless steel slabs are produced by only a few steel companies that may also produce a11oy steel or tool steel slabs using the same melting and casting equipment. Melt shops that produce stainless steel blooms and billets are generally of smaller scale than those used to produce stainless steel slabs and those used to produce carbon and alloy steel billets and blooms. Stainless steel bloom and billet melt shops often produce tool steel, specialized carbon and alloy steel, and a variety of nonsubject nickelbased and other alloys (often called 'superalloys').
