METHOD TO CONTROL METAL TEMPERATURE IN CONVERTER Russian patent published in 1995 - IPC

FIELD: oxygen-converter steel production. SUBSTANCE: in method to control metal temperature in converter they calculate metal temperature by balance method with usage of information about measuring temperature of outgoing gasses and share of CO and CO₂ in the gasses. Preliminary total consumption of oxygen by the smelt is determined without due account of CO and CO₂ after-burning degree and iron oxidation. After oxygen blow-down in amount, that is equal to preliminary determined, metal temperature calculation is carried out with due account of CO and CO₂ degree of after-burning in outgoing gasses. After beginning of the last peak of steam consumption in boiler-utilizer calculation of metal temperature is carried out with due account of iron oxidation. EFFECT: method is used in oxygen-converter steel production. 1 dwg, 1 tbl
