FIELD: metallurgy. ^ SUBSTANCE: method of automatic control of metallurgic raw material roasting in boiling layer furnace provided with premix chamber is based upon measurement of charge consumption, blowing discharge or blowing pressure value under furnace hearth and under premix chamber hearth, measurement of value of deviation of charge consumption from its preset value and upon difference in blowing pressure under premix chamber hearth and furnace hearth. The difference is simultaneously corrected for value of deviation of charge consumption from its preset value. Blowing pressure under premix chamber hearth is subjected to change proportionally to pressure difference. ^ EFFECT: improved efficiency of control. ^ 2 dwg
