Abstract

Abstract: Based on the prototype of 30 t tundish in a steelworks a " belly" induction heating tundish with single channel to reduce the erosion of the wall of tundish has been designed. The flow behavior of liquid steel of the " belly" induction heating tundish is studied by numerical simulation method, and the influence of the volume of the front cavity on the flow state of liquid steel is investigated. The results show that "belly'' can significantly reduce the erosion of the wall of tundish posterior cavity, the average residence time of the " belly" tundish is prolonged by 3. 83% ~ 6. 44% , and the dead zone volume decreases by 5. 6% ~5. 93% ； as the front cavity volume is 1. 06 m³, the average residence time of liquid steel is the longest； as the nozzle flow of tundish is 150 kg/min and 200 kg/min, the longest average residence time is 678 s and 569 s respectively and the minimum proportion of dead zone volume is 5. 87% and 0. 55% respectively./p>

摘要： 以钢厂30 t中间包为原型,设计了一种减轻包壁冲刷的"鼓肚式"单流通道感应加热中间包。采用数值模拟方法研究了"鼓肚式"感应加热中间包的钢液流动行为,探究了前腔体积对钢液流动状态的影响。研究结果表明,"鼓肚"显著减轻了中间包后腔包壁的冲刷,该"鼓肚式"中间包其平均停留时间延长3.83%~6.44%,死区体积减小5.6%~5.93%。前腔体积为1.06 m~3时,钢液平均停留时间最长。中间包水口流量分别为150 kg/min和200 kg/min时,平均停留时间最长分别为678 s和569 s;死区体积比例最小分别为5.87%和0.55%。
