Abstract

1364792 Converter steelmaking CENTRE DE RECHERCHES METALLURGIQUES-CENTRUM VOOR RESEARCH IN DE METALLURGIE 17 Jan 1972 [18 Jan 1971 (2)] 2187/72 Heading C7D [Also in Division F4] Steel is made in a converter having one or more tuyeres opening at the internal surface of the bottom and one or more tuyeres in the side wall below the surface of the molten metal and opening at the internal surface of the side wall. Oxygen is injected through the tuyeres and the relative amounts of bottom and side wall injection are adjusted during the process. At the beginning of the process oxygen may be blown mainly through the bottom tuyeres until the greater part of the silicon has been oxidized. The relative amount of oxygen admitted through the side wall is then increased during addition of lime to maintain the slag in a fluid and oxidized state. When the lime addition is completed bottom blowing is increased to complete oxidation of carbon. The side wall tuyeres may be disposed to produce jets directed obliquely upwards, towards the centre of the converter and/or tangentially to impart rotary movement to the melt.
