1200辊式矫正机是五十年代的产品。包钢轨梁厂投产后,从1970年3月开始,用该机矫正50公斤/米钢轨及其他品种的型钢。自1976年以后,又用来骄正60公斤/米钢轨。到1983年,为满足铁路运输发展的需要,色钢轨梁厂把研制新产品75公斤/米钢轨列入计划,提出对1200辊式矫正机矫正75公斤/米钢轨可行性做技术论证。根据对矫正机论
1200 roller straightening machine is a product of the fifties. Baotou rail beam plant put into operation, starting from March 1970, with the aircraft to correct 50 kg / m rails and other types of steel. Since 1976, it has been used to proudly weigh 60 kg / m rails. By 1983, in order to meet the needs of the development of railway transportation, the color steel rail beam plant included in the plan the development of a new product of 75 kg / m, proposed the feasibility of correcting the feasibility of the 1200 kilometer straightening machine on a 75 kg / m rail. According to the correction machine theory
