Method of manufacturing molten iron insulation material in blast furnace industry

摘要

The present invention is used as a thermal insulation material in the water supply according to the molten iron characteristics of the blast furnace by mixing a wet ratio of the coal-containing wet sludge generated in the water treatment process of the blast furnace process wet vibration damper and the carburizing coke generated during the crushing process of the coke manufacturing process in a certain ratio The present invention relates to a method for manufacturing molten iron insulation material in blast furnace operation.;The present invention is a molten iron lagging production plant 140 for the carburizing coke generated in the coke process (120), the wet sludge generated in the blast furnace process 100 adjusted to less than 4% of its own moisture in the stirring tank 110 and the coke process (120) The step 130 of conveying the mixture, the step 150 of mixing the carbonized wet sludge and the carburized coke at a volume ratio of 30: 70, and to crush the mixture in the mixing step 150 to a particle diameter of 1 to 3 mm Step 160, the step of drying the insulation obtained in the crushing step 160 with 2 to 3% of its own moisture (170), and the powder insulator obtained in the drying step 170 for use in the blast furnace It consists of a step 180 of quantitative standardized packaging.;According to the present invention as described above, by providing a large amount of thermal insulation material with excellent thermal insulation and stable supply without outsourcing, the manufacturing cost of the molten iron is reduced, and the thermal insulation material contains its own moisture, thereby reducing environmental problems such as air pollution. The effect of doubling the warming action by the exothermic reaction while in contact combustion with the melt is provided.
