导语:我国炼钢市场长期依赖进口矿石的局面由来已久,据金银岛资讯数据测算,2015年进口矿占我国铁矿石总供应量的比重可以达到70%,而国内矿仅占30%左右;并且由于种种客观条件的限制,我国矿山根本无法与国外低成本矿山竞争,但要想改变这种局面,其实是有一条“捷径”可走的,那就是废钢。据目前所知,废钢是唯一可以替代铁矿石炼钢的原料,据研究,每用一吨废钢可节约0.4吨的焦炭,大约1吨左右的原煤,同时还可以减少2-3吨铁矿石的使用和4-5吨原生矿的开采;
Lead: China’s steel market has long been dependent on imported ore situation for a long time, according to Treasure Island information data, imported ore in 2015 accounted for the proportion of China’s total iron ore supply can reach 70%, while the domestic mine accounts for only 30% ; And due to various objective conditions, our mines can not compete with foreign low-cost mines at all, but in order to change this situation, there is actually a “shortcut” to go, that is scrap. As far as we know, scrap is the only raw material that can replace iron ore. According to the research, it can save 0.4 tons of coke, about 1 ton of raw coal per ton of scrap, and reduce 2-3 tons of iron ore Use and 4-5 tons of primary ore mining;
