随着现代科学技术、现代工业的发展,对低磷钢的需求量迅速增长,因此迫使我们深入研究磷的去除及如何获得低磷铁合金。铁合金脱磷的重点是锰合金和铬合金。我国现有的锰矿多为贫矿,且有部分高磷、高铁、高硅矿。由于原料关系,铁合金厂所生产的锰铁及硅锰合金含磷较高,既影响其销售价格,又不能满足炼钢工业要求。铁合金
With the development of modern science and technology and modern industry, the demand for low phosphorus steels has rapidly increased, forcing us to study in depth the removal of phosphorus and how to obtain low phosphorus ferroalloys. Ferroalloy dephosphorization focus is manganese alloy and chrome alloy. Most of our existing manganese ore is poor ore, and some high-phosphorus, high-speed rail, high-silicon ore. Due to the raw material relations, ferromanganese and ferromanganese produced by ferroalloy plant have high phosphorus content, which not only affects the selling price but also can not meet the requirements of steelmaking industry. ferroalloy
