Abstract
The present invention is process of producing refractory material with industrial slag. The present invention features that the production process includes the following steps: crushing industrial slag with water content lower than 20 %; milling into superfine material of 100-300 mesh; mixing the superfine material with compounded curing agent in the weight ratio of 65-75 wt% to 25-35 wt% in a stirrer; molding the mixture; and demolding and naturally curing to obtain the product. The present invention can eliminate the pollution of industrial slag while producing refractory material in relatively lower cost.
