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

FIELD: oxygen-converter steel production. SUBSTANCE: method provides for usage of balance method to calculate metal temperature, that differs in the way that they preliminary calculate total consumption of oxygen for blow-down without due account of CO to CO₂ after-burning and iron oxidation, and after oxygen blow-down in amount, that is equal to preliminary determined, they make calculation from time to time of metal temperature with due account of CO and CO₂ after-burning, and after outgoing gasses CO drop below 10 calculation of metal temperature is carried out with due account of iron oxidation. EFFECT: method is used in oxygen-converter steel production. 1 tbl
