摘要
钢渣具有高碱度的特点,当碱度>2时转炉渣中的氧化钙将有一部分以游离氧化钙的形式存在。游离氧化钙是造成转炉渣膨胀的主要因素。本试验采用压蒸法测定了高炉渣和转炉渣的膨胀性,考虑了粒度和陈化时间对转炉渣膨胀性的影响,为高炉渣和转炉渣的应用提供依据。
Steel slag has high alkalinity.Over 2 of alkalinity,parts of CaO are free CaO in BOF slag.Free CaO is the main component affecting its distensibility of BOF slag.The distensibility of BF and BOF slags was measured using steam test method and the effects of size and ageing time on the distensibility were investigated.This method gives evidence for application of BF and BOF slags.
