The effect of following variables on the metallurgical criterion has been studied by the mathematical model of heat transfer: casting speed, spray water intensity, water distribution in spray zone, superheat in tundish, convection in liquid pool and temperature of spray water. Considering these factors, a nomogram of the productivity related to slab thickness, casting speed, spray water intensity and depth of liquid pool was prepared so as to selecte reasonably the technological parameters and to control scientifically the operation. 收稿日期: 1984-03-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 蔡开科 刘凤荣 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1984/V20/I3/252 1 Birat, J.
