METHOD FOR CHARGING RAW MATERIAL INTO BELL-LESS BLAST FURNACE, AND BLAST FURNACE OPERATION METHOD

摘要

Provided are a method for charging raw materials into a bell-less blast furnace, the method enabling raw materials to be charged into a predetermined position in a furnace interior without compromising productivity, and a blast furnace operation method that uses the method for charging raw materials.;A method for charging raw materials into a bell-less blast furnace includes charging an iron source material and a carbonaceous material into a furnace interior of the blast furnace by rotating a distribution chute. The distribution chute includes a diversion plate at an end of the distribution chute, the diversion plate being inclined downward relative to a conveying direction of the distribution chute, and a rotational speed of the distribution chute is greater than 10 rpm.
