长城钢厂3150挤压机与133张减机配套后,133张减机长期未能发挥作用,这个问题从根本上说,它反映了我国张减生产的落后状况。我国研究张减生产起步较晚,但多年来国家花费在这方面的人力、物力和财力却是巨大的。1967年,国家刚考虑从国外引进张减机,国内研究工作的重点就摆在张减机的试制上。当时着重研究的是设备的结构,力能参数的测定,工艺参数的确定等,对配套问题却没有重视。待到张减机组试制成功后,配套问题才提到议事日程上来。最初,该试验
After the Great Wall Steel 3150 Extruder and 133 LME units have been matched, 133 LMRTs have failed to function for a long time. This problem basically reflects the backward state of China’s reduced-production. However, over the years, the manpower, material and financial resources that the country spends in this regard have been enormous. In 1967, the state just considered the introduction of a reduction machine from abroad. The focus of domestic research work was put on trial production of a reduction machine. At that time, the study focused on the structure of the equipment, the determination of the strength and energy parameters, the determination of the process parameters, and so on, but did not attach importance to the matching problems. After the trial of Zhang Jianfei units succeeded, the supporting issues were mentioned in the agenda. Initially, the test
