钢渣综合利用优化方案的试验研究

针对钢渣粉生产过程中能耗大、成本高的问题,提出并论证了一种钢渣综合利用的优化方案。即在工业利用钢渣前,首先在实验室对钢渣的耐磨性等进行分类试验,用耐磨性来反映其磨细能耗的大小,易磨细即磨细能耗较低的钢渣可作为水泥活性掺合料的首选,然后再进行替代水泥的可行性试验,据其替代后的效果做最终判断。磨细能耗高的钢渣则用作普通的路基骨料。这种优化利用方案不仅可以为企业创造更好的效益而且还能更有效地利用废物,节约能源。

Experimental study on optimization scheme of steel slag comprehensive utilization

An optimized scheme of comprehensive utilizing steel slag was put forward and proved for deal with high energy consumption and cost in the production of steel slag powder(SSP)i.e.before industrial utilization of steel slag, it should have classification test in laboratory according to its wear resistance. The wear resistance is reflected by energy consumption of grinding. The easily grind steel slag has low energy consumption that should first be selected as cement active admixture, then feasibility test of substitute for cement should be made and the final decision should be made based on its substitution effect. The steel slag has high energy consumption can be used as normal road bed aggregate.The optimized scheme of utilization can not only create better benefit for enterprise but also utilize the wastes more effectively and saving energy.
