【摘要】 根据相似性原理,对管式和板式两种空气喷吹冷却系统的传热特性进行了实验研究,获得了空气喷吹冷却系统换热系数的准数方程.通过建立大型转炉温度场的有限元分析模型,证实了采用空气喷吹冷却系统后能大幅度降低炉壳温度,并最终完成了宝钢300t转炉风冷系统设计,该系统已于2000年9月20日正式投入生产.更多还原

【Abstract】 The heat transfer characteristics of the plate-type and pipe-type air jet cooling systems have been investigated experimentally according to the similarity principle.The criteria formulas of two types air jet cooling systems are established.A FEM model has been established to analyze temperature fields in the BOF shell and lining.It is proved from the result of FEM simulation that air jet cooling technique is the effective method to control the shell temperature.At the same time, a new air jet cooling system on 300t BOF in Baosteel had been designed and has been employing since September 20,2000.更多还原
