The Different of Other Brand
Rail thermit welding technology has simple equipment and flexible operation mode. It is especially suitable for in-situ welding for repairing the broken rail and welding of seamless rail turnout across sections. It is currently widely used in China and railway welding abroad.
China started research on rail aluminothermic welding technology since 1952, The ZTK-1 rail aluminothermic welding product developed in 2006, it has passed the technical inspection by the Ministry of Railway Transportation Bureau. In 2007, a study on improving the performance of rail aluminothermic welding joints was carried out. The product testing performance reached the level of similar products to other brands, some of the performances exceeded. At present, the product has been used in domestic high-speed, heavy-duty lines and welding in plateau alpine climates.
In the year of 2010, the large-scale production workshops with 2500㎡and its production equipment was carried out for the supporting construction. A total of 12 lines for sand mould production, crucible automated equipment were put into use, as well as thermit portion automated production line was established, which greatly guaranteed the stability of thermit welding portion.
The difference between our materials and other brands:
