众所周知,炼钢生产的一个显著特点是要消耗大量的热能,与此同时,在平炉、电炉和在转炉中又有很大的节能潜力。 在A.Γ沙里莫夫和A.Φ.卡勃鲁科夫斯基的论文中,对转炉生产中的能耗问题给予极大关注,作者们认为尤其可以通过减少生铁料的用量来达到节能目的。 顿河黑色冶金科学研究所对160吨转炉炼钢工艺进行的研究表明,加入无烟煤(占金属料重量的0.6～0.7％)能降低生铁料用量。无烟煤是在装废钢之前和石灰一起加到转炉底部的。按此方法进行冶炼,可降低生铁料用量30～35公斤/吨钢。在转炉中加入
It is a well-known fact that one notable feature of steel-making production is the consumption of large amounts of heat, in the meantime, and the potential for energy savings in open hearths, electric furnaces and converters. In his treatises on A.Γ Salimov and A.Φ. Kabrukovsky, great attention has been paid to energy consumption in converter production, and the authors believe that energy saving can be achieved, in particular, by reducing the amount of pig iron used purpose. The research conducted by the Don Black Institute of Black Metallurgy on a 160-ton BOF steelmaking process shows that adding anthracite (0.6-0.7% by weight of the metal charge) can reduce the amount of pig iron used. Anthracite is added to the bottom of the converter together with the lime before the scrap is loaded. According to this method for smelting, pig iron can reduce the amount of 30 to 35 kg / ton of steel. Add in the converter
