Abstract：
Steel slag is a by-product of steel production, it’s more conductive to achieve the overall requirements of energy conservation and emissions reduction by improving the comprehensive utilization of steel slag. The composition, structure,and phy-chemical property of the steel slag were introduced. The current domestic steel slag treatment process was described in detail. The different utilization methods of steel slag was discussed in the paper, the existing steel slag comprehensive utilization technology was also summarized and analyzed. Finally put forward some suggestions and prospects to the comprehensive utilization of steel slag. On the basis of this, a new separation method of steel slag treatment by a modulated helical magnetic field to separate the liquid steel slag is proposed.
