Abstract
Steel slag is hydraulic cementing material, which is mainly applicable approach to the production of cement, admixture of high performance concrete, road engineering. But as a result of hydration expansion of the free calcium oxide and free magnesium oxide and dicalcium silicate morphological changes which is contained in slag cause poor stability of steel slag used in engineering, the steel slag utilization is very low. Therefore, the key technology of steel slag treatment process is to improve the stability of steel slag. Steel slag is alkaline slag, with lower temperature, the viscosity increases sharply, the liquidity variation, it is one of the important factors affect the steel slag processing, According to the need for different liquidity of steel slag to choose the corresponding steel slag treatment technology. Tank-type hot disintegrating, Rotary cylinder technology processing available to small particle size, good steel slag separation, active promotion of slags, conducive to the comprehensive utilization of steel slag.
