炼钢炼铁肯定有一定数量的铁渣和钢渣伴生。多年以来,钢铁厂都是只管生产钢铁,以钢、铁渣为无用之物,弃置不顾,以致钢、铁渣堆积如山。据资料报道,苏联49家钢铁厂渣山积渣3.5亿 t;其中,马钢积渣近亿吨,占地420ha;乌克兰地区各钢铁厂渣山也有4000万 t 积渣。我国所积钢、铁渣也有二亿余吨,占地近2万亩。仅陈年积渣即已构成公害,又何况每年还有大量新渣上山。此种局面如不及时扭转,势将酿成巨大灾害。可见,问题必须解决,渣害必须治理。
There must be a certain amount of iron slag and steel slag associated with steelmaking. Over the years, the steel mills have all just managed to produce steel and use steel and iron slag as their useless items. They have not disposed of them so that steel and iron slag pile up like mountains. According to the information reported, the 49 steel mills in the Soviet Union slag slag 330 million t; of which, Masteel residue nearly 100 million tons, covering 420ha; Ukraine’s steel mills also have 40 million tons slag dregs. Accumulation of steel in our country, iron slag also has 200 million tons, covering nearly 20000 acres. Only aged residue that has become a public hazard, not to mention a large number of new slag each year up the mountain. If this situation is not reversed in time, the situation will lead to a huge disaster. Visible, the problem must be solved, slag harm must be governance.
