过去我厂三吨自由锻造加热炉的炉门框为铸件,用不到半年就被烧坏,只得仃产修炉子。不但费时、费力、浪费大量耐火砖和钢材,而且严重影响生产的顺利进行。针对这个问题,1972年,我们组织成了车间领导、工人、技术人员三结合的革新小组,在不到一个月时间内,试验成功了自动循环水冷炉门框。经几年来的使用,效果很好。自动循环水冷炉门框的水循环系统示意图如图1所示。水冷炉门框1是用20毫米厚
In the past I plant three tons of free forging furnace furnace door frame for the castings, less than six months to be burned, had only Ding production furnace repair. Not only time-consuming, laborious, waste a lot of refractory bricks and steel, but also seriously affect the smooth progress of production. In response to this problem, in 1972, we organized an innovation team consisting of workshop leaders, workers and technicians. In less than a month, we successfully tested the automatic circulating water-cooled door frame. After several years of use, the effect is very good. Automatically circulating water-cooled door frame water circulation system diagram shown in Figure 1. Water-cooled oven door frame 1 is 20mm thick
