Steel slag treatment agent and steel slag recovery treatment method
The invention discloses a steel slag treatment agent and a steel slag recovery treatment method, and belongs to the technical field of ferrous metallurgy. The main component of the steel slag treating agent is formed by mixing one or more of sodium silicate, sodium aluminate, sodium aluminosilicate, sodium sulfate, calcium sulfate, calcium hydroxide, aluminum sulfate and aluminum hydroxide. The steel slag recovery treatment method comprises the following steps: (1) naturally cooling high-temperature liquid steel slag to low temperature; (2) putting the low-temperature liquid steel slag into a hot and stuffy tank, adding water to cover the tank, and sealing for a period of time; (3) intermittently spraying the diluent of the steel slag treatment agent to the steel slag in the hot and stuffy tank; and (4) performing magnetic separation to obtain high-performance steel slag and iron. The formula of the steel slag treating agent can promote separation of slag and iron in the steel slag and promote conversion of unsteady substances such as free calcium oxide and free magnesium oxide in the steel slag into harmless calcium hydroxide and magnesium hydroxide, chemical components of the steel slag are scientifically and reasonably adjusted, more gelling performance is reserved, and high-performance steel slag is generated from common steel slag.
本发明公开了一种钢渣处理剂及钢渣的回收处理方法，属于钢铁冶金技术领域。钢渣处理剂主要成分由硅酸钠、铝酸钠、硅铝酸钠、硫酸钠、硫酸钙、氢氧化钙、硫酸铝、氢氧化铝中的一种或几种混合而成。钢渣的回收处理方法步骤为：(1)将高温液态钢渣自然冷却至低温；(2)将低温液态钢渣置于热闷罐中，并加水盖罐密封一段时间；(3)向热闷罐内的钢渣间歇喷洒上述的钢渣处理剂的稀释液；(4)磁选，得到高性能钢渣和铁。本发明的钢渣处理剂配方可以促进钢渣中渣铁分离，促进钢渣中游离氧化钙、游离氧化镁等不安定物质转化为无害的氢氧化钙、氢氧化镁，科学合理的调节了钢渣的化学成分，并且保留更多的胶凝性能，使得普通钢渣生成高性能钢渣。
