摘要
转炉渣具有高碱度的特点,当碱度R>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。实验采用压蒸法测定了转炉渣的膨胀性,分析了粒度和陈化时间对转炉渣膨胀性的影响,为转炉渣的应用提供依据。
BOF slag has high alkalinity. When the alkalinity is over two, part of CaO are free in BOF slag. Free CaO is the main factor affecting the distensibility of slag. The distensibility of BOF slag was measured by steam test method and the effect of size and ageing time on the distensibility was investigated. These give evidence for application of BOF slag.
