一、锰铁脱磷的意义自然界的锰资源极为丰富,特别是在海底有大量锰结核。据估计,锰将成为仅次于铁的另一种最便宜的金属。目前,主要利用大陆蕴藏的锰矿炼成锰铁合金用于钢铁生产。我国有较丰富的锰矿资源,但多为贫矿,且有部分高磷、高铁、高硅矿。高硅、高铁与低锰的问题可采取多炼硅锰和放宽锰含量标准的办法来解决。炼钢时推广应用硅锰和较低锰含量的锰铁应无特殊困难。比较麻烦的是磷。炼钢厂普遍反映锰铁 First, the significance of dephosphorization of manganese Natural resources are extremely rich in manganese, especially in the sea there is a large number of manganese nodules. It is estimated that manganese will become another cheapest metal after iron. At present, the main use of mainland deposits of manganese ore into ferromanganese for steel production. My country has a wealth of manganese resources, but mostly poor ore, and some high-phosphorus, high-speed rail, high-silicon ore. The problems of high silicon, high-speed rail and low-manganese can be solved by refining silicon manganese and relaxing the manganese content standard. There should be no special difficulties in popularizing the application of ferromanganese and lower manganese content ferromanganese during steelmaking. More troublesome is phosphorus. Steel mills generally reflect ferromanganese
