摘　　要：原料磨衬板壁厚相差大 ,需要大冒口补缩。为提高工艺出品率 ,生产中按照均衡凝固理论进行无冒口工艺设计 ,取得用冒口补缩同样的效果。无冒口铸造工艺设计着重在均衡各部位钢液温度 ,减小凝固温差 ,内浇口开在壁薄处等方面进行工艺设计。Original material milling’s linear board needs feeding in large scale riser because there are many differences in thickness. According to the proportional solidification theory to adopt non-riser design on it, the feeding result does the same as the riser does. The emphases of non-riser foundry technology are to balance steel liquid temperature on different position, reduce the difference in solidifying temperature, put the ingate in the thin wall position of linear board.

关 键 词：原料磨衬板 均衡凝固 浇注温度 浇注速度
