Title: Operation of blast furnace
Inventor: NAKATANI GENJI
IPC: C21B5/00
Filed: 1978-05-15
Abstract: PURPOSE:To improve the bad conditions, e.g., load lowering, shelving, etc., of furnace by the procedure in which an appropriate amount of moisture is included in raw materials to be charged into blast furnace, the deposition distribution of raw materials in furnace is altered, and the flow rate distribution of gas in furnace is controlled. CONSTITUTION:The upper part of the hopper 5 at the top of the blast furnace 1 is provided with the belt conveyer 6 from which raw materials, e.g., coke, iron ore, etc., are charged into the furnace. In charging raw materials, an appropriate amount of moisture is added to coke or iron ores, as needed, from the water supplier 9 with the flow meter 7 and the flow regulator 8, where the apparent specific gravity of the raw material to which was added water becomes greater and thus it centers around the central part of the furnace. When coke centers around the central part of the furnace, the ascending flow rate of gas at the central part of the furnace becomes faster than that at the surrounding portion of the furnace and thus the temperature becomes higher alike. Thus, the flow rate of gas in the furnace can be freely controlled and also the temperature distribution in the furnace can be regulated, thus stabilizing the conditions of the furnace.
