摘要
A method and system for producing low-alkalinity sulphoaluminate cement with a new mineral system using steel slag. The method includes the following steps: evenly mixing and homogenizing ground steel slag with dry desulfurization gypsum, aluminum ash and carbide slag according to a set ratio; and conveying the homogenized raw meal to a rotary kiln for calcination to obtain cement clinker, where the calcination temperature is 1200° C.-1270° C., and the calcination time is 20-60 min; the alkalinity modulus of the homogenized cement raw meal is 0.81-0.9, and the Fe2O3 content is 8-13%. The method breaks through the requirements on contents of calcium, aluminum and iron in traditional sulphoaluminate cement production, and realizes application of a large amount of steel slag.
