To improve the efficiency of the steel industry, the company has taken various measures to reduce costs. In the main process of steel slag cement, the atmosphere contains CaO=2O-CaF, and the Cr6-3 cement in water slag cement is a good and CaO related resource, which not only saves energy and benefits the environment, but also helps to reduce costs and increase efficiency. However, due to the high dust content and solid content in the parts, these are not conducive to the practical utilization of steel slag. The current sluggish situation in the steel industry is difficult to change, and the pressure of environmental protection is still relatively small. In addition, steel slag with resource supply is still in a difficult situation. Therefore, we believe that the steel industry should not have a very strong environmental, social and economic impact in the past
