Hydraulic Model Experiment and Analysis on the Deadman of BF Hearth
LUO Xiaguang
Abstract：A hydraulic model experiment on BF simulation of deadman in iron-making has been made. The effects of deadman change on flow field in the hearth has been studied. The results showed that: with the decreasing of Deadman volume, Circulation will be weakened. It is very favorable to reduce the erosion of hearth wall surface. Due to the increasing of deadman porosity which can maintain better hot strength of coke and is conducive to the reduction of hearth circulation, the life of furnace hearth can be prolonged. With the increasing of the no focal space layer height on the bottom namely the floating height can be increased. This process can reduce the wall velocity and prolong the life of furnace hearth.
