| Abstract Scope |
Under the modern blast furnace process conditions, replace the coke or pulverized coal by hydrogen, improve the efficiency of hydrogen reduction in the blast furnace, realize carbon-hydrogen coupling reduction, in different process section and temperature range, give full play to the advantages of carbon direct reduction, CO indirect reduction and H2 reduction, in heat transfer, mass transfer, momentum transmission and metallurgical reaction engineering, through process development and operation optimization, reduce carbon fuel consumption, blast furnace fuel ratio to below 460kg/t, realize rich hydrogenation and low carbonization of blast furnace iron making process. The changes of theoretical combustion temperature of tuyere raceway and bosh gas volume of the blast furnace are researched. The reduction thermodynamic parameters of different temperature range and zone of blast furnace are calculated. The process measures of improving hydrogen utilization ratio and hydrogen carbon replacement ratio in the operation of blast furnace are discussed. |
