KR采用机械搅拌方式脱硫,不仅脱硫效率高、脱硫剂消耗少,而且处理过程无外来气体吹入,很少发生喷溅。介绍了一种由内生CO引起的KR过程铁水喷溅现象,研究并论证了喷溅过程的发生机理。研究认为,铁水包内剩余铁或铁氧化物,经过长时间高温烘烤、保温,转化为Fe O;Fe O熔化或与铁水中硅反应成低密度的液态铁橄榄石;生成物上浮过程中,在铁水包内一定深度又与铁水中碳反应生成CO。当搅拌发生时,铁水运动加剧CO的生成速度,进而引起铁水喷溅。高碳、低硅、高温铁水容易发生喷溅。为防止喷溅,应制定铁水包烘烤时间的规范上限。如果铁水包出现"冒火"、"液面涌动"等信号,应谨慎处理或停止处理。

由受力根据刚度分配的原则,引入受力分配系数,对圆环支撑体系水平刚度系数的计算进行了解析式的推导,提出了圆环支撑体系水平刚度系数的简易计算方法,并给出了解析式的修正式。并以某超深基坑圆环支撑体系为例,应用所提出的公式计算该圆环支撑体系的水平刚度系数,并与三维有限元分析结果进行对比,同时分析了不同封闭环梁、发射梁对水平刚度的影响,结果表明:二者误差较小,圆环支撑体系水平刚度主要由受力杆件封闭环梁决定,与发射梁等传力杆件关系不大,依据所提出的解析式进行计算,结果精确且简单易行,可为基坑圆环支撑体系水平刚度系数的取值提供依据。
