Abstract:
1. A method for manufacturing a foam 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 1400° C.-1500° C., and adding a viscosity modifier and/or a color modifier to the molten slag to adjust a viscosity and/or a color of the molten slag according to requirements of a product to be manufactured; introducing the molten slag discharged from the pool for preserving heat and modifying into a foaming pool while adding a foaming agent to the molten slag, wherein the molten slag in the foaming pool is controlled at 1250° C.-1400° C. so as to foam and mold; and maintaining the foamed and molded slag at 800° C.-1000° C. for 20-30 minutes in a non-reducing atmosphere, and then naturally cooling the foamed and molded slag to a room temperature so as to obtain the foam material, wherein the molten slag includes 10-40 wt % of Al
