钢渣是炼钢工艺过程的重要副产物,它不但含有7-10％的铁(在技术水平较低的小型企业含铁更高,甚至超过15％),以及钙、硅、锰、钛、钒、铬和铌等多种有价元素,而且液态渣还含有大量显热。因此,通常说钢渣是一个丰富的大资源库一点也不过份。充分开发钢渣资源、造福人类是我们冶金工作者的责任。湖南省钢铁企业年产钢渣二十万吨以上,长期以来便已用钢渣制成水泥、道路工程材料、农肥、建材制品等,取得了一定的成效。但是尚不理想,仅只利用其中的一部分,而大部分仍然占用场地,堆积成山。更何
Slag is an important by-product of the steelmaking process. It contains not only 7-10% iron (even more than 15% in less skilled small businesses), but also calcium, silicon, manganese, titanium, vanadium , Chromium and niobium and other valuable elements, and liquid slag also contains a lot of sensible heat. Therefore, it is not excessive to say that steel slag is a rich and large resource base. The full development of steel slag resources for the benefit of mankind is our metallurgical workers responsibility. Hunan iron and steel enterprises with an annual output of more than 200,000 tons of steel slag, slag has long been made of cement, road construction materials, fertilizer, building materials and other products, and achieved some success. However, it is still not ideal. Only some of them are used, while most still occupy the site and pile up mountains. More
