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

FIELD: oxygen-converter steel production. SUBSTANCE: method provides for calculation of metal temperature by balance method. Measurement of outgoing gasses temperature differs in the way, that they preliminary calculate total consumption of oxygen to be used for blasting, without taking into consideration iron oxidation and after-burning of CO to CO₂. Oxygen is fed in amount, that is equal to preliminary calculated. Then from time to time metal temperature calculation is made with taking into consideration of degree of CO after-burning to CO₂ and after beginning of temperature drop of outgoing gasses calculation of metal temperature is exercised with due account of iron oxidation. EFFECT: method is used in oxygen-converter steel production. 1 dwg, 1 tbl
