高炉渣的综合回收利用

Recycling and utilization of blast furnace slag

钢铁产业生产过程中产生大量的废渣,产生的高炉渣占50%以上,如何利用好高炉渣,减少其对环境的污染已成为我国钢铁行业的主要问题之一。文章阐述了高炉渣的组成,介绍了高炉渣在玻璃、肥料制品上的应用以及回收高炉渣中的钛元素及热量的举措,并针对我国的利用情况,对未来如何更加合理地利用高炉渣进行了讨论。

The iron and steel industry produces a large amount of waste slag in the process of production. The slag is more than 50% of produced by the blast furnace. How to make good use of blast furnace slag and reducing it’s pollution to the environment has become the main problems of China’s steel industry. The paper describes the chemical composition of the blast furnace slag, and introduces application of the blast furnace slag in the glass and fertilizer industry, and recovery of titanium and heat from the slag, and discusses how to make more rational use of the blast furnace slag in the future based on the current situation in China.
