On March 17, 2007, Panzhihua Iron and Steel Co., Ltd., a 100m long-length on-line heat-treated steel rail, successfully stepped out of the 100m long-length heat-treated rail production line of the new steel vanadium rail beam factory, thus proclaiming that China's first 100m long-length ruler with world-class technology The heat-treated rail production line was completed and put into operation in Panzhihua Iron and Steel.
The production line has been listed as a national high-tech industrialization project. It has been completed and put into production, which has upgraded the production process and technology of Pangang's online heat-treated rail production, further expanding the production scale of Panzhihua Iron and Steel heat treatment rails, and the production efficiency and production capacity are more than the original ones. The 25m online heat treatment rail production line has increased more than three times.
The newly-built 100m long-length on-line heat-treated rail production line can produce heat-treated rails of various strength grades from 9 to 100m in any fixed length, from 37.2 to 75kg/m in any section and from 880 to 1300MPa. According to reports, in recent years, China's railway construction has been developing at a high speed, long-term, and heavy-duty, and the speed and heavy-duty of passenger and freight trains have increased the performance requirements of rails, while heat-treated rails can be improved over ordinary rails. 1 to 3 times the service life.
