For the efficient blast furnace operation, a computer system having following functions was developed and has been used in Hirohata works.
(1) Control function of gas flow distribution : The accuracy of gas flow detection can be improved by this function, and the efficient gas utilization has been achieved.
(2) Control function of heat balance : This function consists of estimation model and operational guide for heat balance operation, and it helps stabilization of hot metal quality.
(3) Prevention function of abnormal condition : The abnormal condition can be forecasted and prevented by this function, and the stable condition in blast furnace has been obtained.
(4) Function of operation analysis : This function supports other functions by rapidly analysing operational data.
These functions have been refined according to the change of circumstances successively, and contributing to efficient blast furnace operation.
