Method for manufacturing planar inorganic non-metallic material using molten slag

摘要

A method for manufacturing a planar inorganic non-metallic material using a molten slag. The method comprises these steps: feeding the molten slag into a thermal insulated conditioning pool and maintaining the temperature of the molten slag between 1,450°C and 1,600°C; modifying the color and/or the viscosity on the basis of the requirements of a product to be manufactured; feeding the conditioned molten slag into a float process production pool where tin or a tin alloy is used as a carrier; removing at a temperature between 1,000°C and 1,300°C from the float process production pool the planar inorganic non-metallic material acquired via a float process; thermally insulating the planar inorganic non-metallic material at a temperature between 600°C and 900°C in a non-reductive atmosphere for a period of 0.5 to two hours, and then cooling gradually to room temperature within one to two hours to acquire the planar inorganic non-metallic material. The method provides an energy conserving and high efficiency way of utilizing blast furnace slag, the planar inorganic non-metallic material is characterized by color stability, wear resistance, pressure resistance, non-flakiness, a low expansion coefficient, and a low shrinkage rate.
