【摘要】 铁水炉外脱硫是提高钢铁质量的重要环节之一。目前,广泛采用的铁水炉外脱硫主要方法是喷吹法和KR搅拌法。KR搅拌法因为具有脱硫剂单耗低、脱硫效果稳定和良好的搅拌动力学条件而被企业广泛采用。示踪实验是研究水模型中混合时间的基本方法,本文以聚氯乙烯颗粒为示踪剂,通过水模型实验模拟研究了搅拌模式、浸入深度对固态示踪剂分散情况的影响,其结果对氧化钙碳化钙等脱硫剂的KR搅拌脱硫工艺具有一定指导意义。更多还原

【Abstract】 External desulfurization of hot metal is a important process to improve the steel quality,Usually extensively adopted method of desulfurization in molten iron is injection method and KR stirring method.Because of lower desulfurizer consumption,the effect of desulfurization stability and good dynamics conditions,KR stirring method were widely used.Tracer is a good way for us to study the water flow by rotating in water model.The main purpose of the tracer experiment in water model is to compare expanding industrial prototype with industrial prototype,and research and analysis the effect of the immersion depth,rotation mode and other factors on tracer particles in the liquid dispersion.The experimental result of cold water model of tracer can have a significant to desulfurization in molten iron by CaO and CaC₂.更多还原
