Abstract
The invention relates to a BAOSHEREX iron making process for smelting molten iron through a two-step method, and belongs to the technical field of iron making technology. According to the process, vertical furnace type pre-reduction is performed, a melting gasification furnace is additionally arranged outside a vertical furnace type pre-reduction furnace, oxygen and coal powder are sprayed through oxygen wind ports uniformly distributed on the hearth of the melting gasification furnace, and the produced heat can meet the requirements of the molten iron and slag production. According to the present invention, the coal content in the fuel of the BAOSHEREX iron making process is 80-85 wt%, only 500-600 m<3>/t iron of the oxygen is used, and 15-20% wt of the coke is used to produce the high-quality hot molten iron with a temperature of 1350-1480 DEG C, the granulated water slag and the high-quality coal gas; and the process has advantages of high capacity, high efficiency, low energy consumption, low emission, and low cost.
