Tang Steel 2#blast furnace adheres to the operation system of stabilizing edge and developing center after open-ing.In the daily operation of blast furnace,through the development of a reasonable charging system,high wind speed,high kinetic energy,high oxygen enrichment,strengthening the management of peripheral raw fuel and other measures,un-der the process conditions of 40%pellet ratio,efficient smelting was achieved,the coal ratio was 160 kg/t,and the utiliza-tion coefficient of blast furnace reached a record high level of 3.0 t/(m3·d).
