Abstract

Hot blast flow control valves which can control the flow rate of hot blast at each tuyere and their control system have been developed and applied to Keihin No. 1 BF. These technologies contribute to stable and rational operation compared with conventional ones. This presentation describes the technology of hot blast flow control valves and its implications on the control of heat load at the lower part, the removal of scab, and the control of tapping conditions.
