钢屑、铁末是冶金工业生产中最好的原料之一。它具有纯洁、含铁金属较高的特点,但也具有体积大、重量小、容易氧化锈蚀的弱点。这一重要资源,过去虽然经过热压成炒毛铁后利用了一部分,但还有相当数量的钢屑、铁末仍被拋弃锈坏成泥,有的甚至被深深地埋在山沟泥坑里而浪费了。目前,这些钢屑、铁末不经过炒毛铁工艺而直接投入平炉炼钢,大大降低了钢铁料的消耗和钢的成本。
Steel scrap, iron is one of the best raw materials in the metallurgical industry. It has a pure, high iron metal characteristics, but also has a bulky, light weight, easy oxidation rust weaknesses. This important resource used to be partly used after being hot-pressed into a hairspray, but there was also a considerable amount of steel shavings. The iron was still abandoned and the rust was turned into mud, and some were even deeply buried in the crater And wasted. At present, these steel shavings and iron powder are put into open hearth steelmaking directly without going through the process of speculated bristle iron, which greatly reduces the consumption of steel materials and the cost of steel.
