来源:新乡市天马工业炉有限公司 发布时间:2019-12-18 16:20 浏览次数:次

Al2O3是高炉炼铁炉渣的重要成分之一,随着Al2O3含量的不断升高,炉渣流动性差、脱硫能力下降等问题日渐突显,对高炉冶炼造成极大危害。针对这一问题,***上普遍采用的应对方式是在烧结工艺中添加MgO。然而,如何添加,添加多少***合适,却是一道***难题。

普遍认识误区,

2015年,我国1000 m3以下高炉渣的平均镁铝比约为0.68,1000~3000 m3高炉渣的平均镁铝比约为0.60,3000 m3以上高炉渣的平均镁铝比约为0.55~0.57。较高的镁铝比不仅增大了渣量、能耗及镁资源的消耗,同时也影响烧结生产及烧结矿的质量。因此,研究烧结-高炉各环节适宜的MgO含量和高炉渣中适宜的MgO/Al2O3比例显得十分必要。

MgO如何添加才能做到优化?
