在伟大领袖毛主席“独立自主、自力更生”和“备战、备荒、为人民”的方针指引下,圆锥轴承内圈热轧新工艺,于去年在烟台轴承厂试验成功并应用于生产。到目前为止,已生产出六种型号圆锥轴承内圈三十余万套。同时也进行了圆锥轴承外圈、球轴承内圈和类似零件如自行车脚闸皮、轴瓦等热轧试验,试验是成功的。生产和试验都是在改装后的代用设备上进行的,目前国内尚无较理想的专用大规格轧环机组。根据去年六月份烟台热轧现场会议纪要要求,在第一机械工业部的领导下,组织了有关厂和科研、设计单位成立了ZH100型轧环机设计组。设计组和广大的革命工人、革命科技人员高举毛泽东思想伟大红旗,在两个阶
Under the guidance of Chairman Mao’s great leader, “Independent, Self-reliance,” and “Preparation for war, preparation for war and for the people,” the new hot rolling technology for the inner cone of the tapered bearing was successfully tested in the Yantai Bearing Factory and applied to the production last year. So far, it has produced more than 300,000 sets of six kinds of conical bearing inner rings. At the same time also carried out the outer cone bearing, ball bearing inner ring and similar parts such as bicycle foot brake pads, bearings and other hot-rolled test, the test was successful. Production and testing are carried out after the conversion of the substitute equipment, at present there is no ideal special large-scale rolling ring unit. According to the requirement of meeting minutes of Yantai hot rolling site in June last year, under the leadership of the first Ministry of Machinery Industry, the relevant plants and research institutes were set up and the designing unit of ZH100 rolling ring machine set up. The design team and a large number of revolutionary workers and revolutionary scientists and technologists hold high the great red banner of Mao Zedong Thought,
