Abstract:
1. A method for manufacturing a plate inorganic nonmetal material by using a molten slag, comprising: introducing the molten slag into a pool for preserving heat and modifying, wherein a temperature of the molten slag is maintained at 1450° C.-1600° C., and modifying a viscosity and/or a color of the molten slag according to requirements of a product to be manufactured; introducing the modified molten slag into a float process furnace using tin or tin alloy as a carrier and preparing the plate inorganic nonmetal material from the modified molten slag, and discharging the plate inorganic nonmetal material at 1000-1300° C.; and maintaining the plate inorganic nonmetal material at 600° C.-900° C. for 0.5-2 hours in a non-reducing atmosphere, and then gradually cooling the plate inorganic nonmetal material to a room temperature within 1-2 hours, wherein the molten slag includes 10-40 wt % of Al
