Production and use of silicon calcium slag

Silicon-calcium slag usually refers to the ash with alkali and limestone sintering, and then through the wet extraction of alumina, alkali recovery after the remaining solid residue, because it mainly contains two elements of silica-calcium, known as silica-calcium slag. According to the analysis of silicon calcium slag powder by many manufacturers, the content of calcium oxide (CaO) is more than 55%, and the content of silicon dioxide (SiO2) is more than 25%. The use of silicon calcium slag powder
Calcium silicon is mainly used as inoculant for cast iron. The reduction capacity of silicon calcium powder alloy is very strong, and it is also used as a deoxidizer of high-quality steel.
According to the characteristics of calcium silicate slag, combined with the current advanced technology, a new comprehensive utilization method of calcium silicate slag powder production by using HLM slag vertical grinding line is developed, including the following steps: Under the current new policy of environmental protection, the industrial solid waste treatment and comprehensive utilization industry has reached a consensus, enterprises no longer discharge the solid waste of silicon calcium slag, but the purchase of slag mill to powder the silicon calcium slag and then reuse, the economic benefits are very considerable. Some of them are used in the field of smelting industry, some are used in the field of cement building materials, and some are used in the field of agriculture. The comprehensive utilization of silicon calcium slag solid waste will produce some economic benefits.
