过去齐齐哈尔钢厂二车间500轧机一架前翻转热钢坯的阴阳面都是用人工进行的。1974年222工段的工人和东北重机学院轧钢专业部份师生在党组织领导下,组成三结合技术革新小组,在车间各部门的协助下,仅用一个半月的时间,因陋就简,修旧利废,制造曲轴采用了组合式的热装工艺,吸取兄弟厂的先进经验,制成一台阴阳面翻钢机,不仅能翻钢坯,并且能翻500轧机一架前的各种矩形断面轧件,从而解除了多年来轧钢工人的笨重体力劳动,改善了劳动条件,促进了生产发展。这台翻钢机的机构如图1所示。技术性能及主要数据为:
In the past Qiqihar Iron and Steel Mill 500 two rolling a hot rolling machine before and after the yin and yang are manually carried out. Under the leadership of the party organizations, workers in Section 222 and part of the rolling mill of the Northeast Heavy Machinery College in 1974 formed a group of three with the technical innovation group. With the assistance of various departments in the workshop, it took only a month and a half for simple, Waste, the manufacture of crankshaft with a combination of hot-filling process, learn from the advanced experience of brothers plant, made of a yin and Yang machine, not only can billet, and can turn 500 rolling mill before a variety of rectangular section rolling , Thus relieving the heavy labor of the steel-rolling workers over the years, improving working conditions and promoting the development of production. The structure of this machine is shown in Figure 1. Technical performance and main data are as follows:
