Title:

METHOD FOR MANUFACTURING REDUCTIVE STONE MATERIAL USING MOLTEN SLAG

Document Type and Number:

WIPO Patent Application WO/2012/041172

Kind Code:

A1

Abstract:

A method for manufacturing a reductive stone material using a molten slag. The method comprises these steps: controlling the molten slag at a temperature between 1,400°C and 1,500°C, and cast molding at a controlled temperature; thermally insulating the molded molten slag at a temperature between 800°C and 1,000°C in a non-reductive atmosphere for one to five hours, and then cooling gradually to room temperature within two to five hours to acquire the reductive stone material. The method provides an energy conserving and high efficiency way of utilizing blast furnace slag. The reductive stone material produced is characterized by color stability, wear resistance, pressure resistance, non-flakiness, a low expansion coefficient, and a low contractability rate.
