由于铁路运输事业的不断发展,对重型钢轨的需要日益迫切。为此,包钢与铁道部合作于1976年在国内首次进行了60公斤/米重轨的试制。由于两部的共同努力,钢轨的试制和试生产顺利进行,到1980年12月底,包钢共生产出60公斤/米重轨5.7万余吨,先后在线路上使用。 为了广泛研究包钢60公斤/米重轨母材性能,除了对包钢60公斤/米U(74)重轨投产以来的成分和性能进行数理统计外,最近又搜集了美国和苏联部分碳素轨资料与包钢
Due to the continuous development of railway transportation, the demand for heavy-duty rails has become increasingly urgent. To this end, Baotou and the Ministry of Railways in 1976 in the country for the first time 60 kg / m heavy rail trial. Due to the joint efforts of the two departments, trial production and trial production of rails were carried out smoothly. By the end of December 1980, Baosteel produced a total of 57,000 tons of 60 kilograms / meter heavy rail and used them successively on the line. In order to extensively study the performance of Baosteel’s 60 kg / m heavy rail parent material, in addition to carrying out mathematical statistics on the composition and properties of Baosteel’s 60 kg / m U (74) heavy rail since its commissioning, recently some U.S. and Soviet carbon Rail data and Baotou Steel
