海绵铁是电炉炼钢的优质原料,是废钢的理想代用品。我国废钢十分短缺,海绵铁产品有广阔的市场,特别是冶炼优质钢的电炉更需用纯净的海绵铁冲淡钢带入的有害元素。本生产技术可将内配碳环团矿经过还原焙烧得到金属化率≥90%的海绵铁。铁精矿粉的品位越高,固体还原剂的灰份越低,?
Sponge iron is high-quality raw materials for EAF steelmaking and is an ideal substitute for scrap steel. Scrap is very short, sponge iron products have a vast market, especially the smelting of high-quality steel furnace with pure sponge iron need to dilute the harmful elements into the steel. The production technology can be equipped with carbon ring ore after roasting to obtain a metalization rate of ≥ 90% sponge iron. The higher the grade of iron ore concentrate, the lower the solid reductant ash ,?
