Zusammenfassung:	A method for manufacturing a plate inorganic nonmetal material by using a molten slag includes: 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 an ambient temperature within 1-2 hours. An energy-saving and efficient method for comprehensively utilizing the blast furnace slag is provided. The produced plate inorganic nonmetal material has such characteristics as stable color quality, abrasion resistance, pressure resistance, strong adhesiveness, low coefficient of expansion and low shrinkage ratio.
