W 1-type elastic strip is China high-speed railway passenger dedicated line fastener core component is the rail track fasteners and line base (sleepers or track plate) coupling components, play a fixed rail, rail systems provide flexibility and reduce wheel-rail interaction function. Under the shells of long-term reciprocating shock, vibration, alternating stress conditions of work, to withstand tension and compression, bending, torsion and shear, 350km / h high-speed rail requires high flexibility, high strength, high fatigue resistance and some of the impact toughness The shells of the intrinsic properties of the shells of the relationship to life and traffic safety fastening system. Compared with the shells of the existing railway, high-speed railway shells of a higher, more demanding technical requirements, such as the extensive use of the existing railway B-type bomb assembled displacement fatigue test article was 7.8mm, fatigue amplitude of 0.7mm, high-speed railway with the W1-type bomb assembled displacement fatigue test article was 13.25mm, fatigue amplitude of 1.25mm. W1 type Elastic technical requirements inherent properties: Hardness 42 ~ 47HRC, metallurgical (quenching state) �� 2 ferritic, martensitic ��4 grade metallurgical (tempered state) uniform tempering troostite and back Fire sorbitic surface decarburization �� 0.25mm, residual deformation �� 1.0mm, 5 million times of fatigue fatigue performance is not broken, after fatigue residual deformation �� 1. Omm.
喵网福彩 Anyang City Railway Equipment Co., Ltd is the largest base for the production and sales of various types of shells. Remove 30% of the domestic share of shells, the shells of exports of Russia, Australia and the United States is very optimistic. Well I plant the bomb strip quality, reliable appearance. Domestic and foreign experts alike!
