海砂在球团竖炉生产中的应用

摘要

近年来随着钢铁行业的发展，富矿资源逐渐枯竭，而铁矿石需求却在日益增加，钢铁企业的成本面临着巨大压力，寻找低价矿成为了钢铁行业的重点。海砂储量丰富，除了含有较高的铁元素外，钒钛的含量也较高，且价格低廉。在竖炉球团生产中应用海砂矿，不但可以大幅度降低球团矿成本，其中富含的钒钛还能给高炉带来保护炉缸的效果，成为当前经济料生产条件下高炉护炉、稳定生产的必需料和急需料。%in recent years, with the development of iron and steel industry,iron ore resources are exhausted gradually, and the iron ore demand is increasing, the cost of iron and steel enterprises are faced with tremendous pressure, looking for low-cost ore became the focus of the iron and steel industry. Sand rich reserves, in addition to iron containing high, vanadium and titanium content is higher, and the price is low. Application of sand deposit in shaft furnace pelletizing production, can greatly reduce the cost of pellet, which is rich in vanadium titanium also has protection effect to the blast furnace hearth, become the current economic aggregate production conditions, protection of blast furnace,the stable production of essential materials and in urgent need of material.
