Abstract

PURPOSE: To prevent the erosion of the furnace floor part, by improving the flowing property of fluid in the filled layer at the part higher than the level of the tap ho le and lightening the thermal load to the bricks at the furnace bottom, by selecting the tapping of molten pig iron and slag, the charging of coke, etc. in a specified condition, at the operation of the blast furnace.
