高碱度钢渣蒸汽法处理技术在国内是首次研究成功,这对进一步促进钢渣综合利用具有现实意义。近年来,上海各钢厂的氧气转炉钢渣含有未结合石灰高达10％,风化膨胀严重,阻碍了综合利用。高碱度钢渣经95～100℃饱和蒸汽处理后,使未结合石灰迅速消解,渣的风化膨胀迅速下降以至稳定。这样,基本上解 The high-alkalinity steel slag steam treatment technology has been successfully studied for the first time in China, which is of practical significance to further promote the comprehensive utilization of steel slag. In recent years, oxygen steel converter steel slags from various steel mills in Shanghai contain up to 10% of unbound lime, which has caused severe weathering and swells, hindering comprehensive utilization. The high alkalinity steel slag is treated with saturated steam at 95 to 100°C to rapidly dissolve the unbound lime, and the weathering expansion of the slag is rapidly reduced and stabilized. In this way, basically solutions
