The existence of various rail products has gradually become the typical existence of people’s daily production, with the continuous development of the social economy, the types of rails are also undergoing important changes, among them, the use of the track is more obvious, regarding the improvement of the mechanical performance in the installation of the track, I have introduced the following summary for you.
The physical and mechanical properties of the rail steel include the strength limit ?b, the yield limit ?s, the fatigue limit ?r, the elongation ?5, the area shrinkage ?, the impact toughness (drop weight test) ?h, hardness, etc. These indicators have a great impact on the bearing capacity, wear, crushing, fracture and other damage of the track.
The wheel-rail impact at the rail joint is very large. In order to strengthen the anti-wear ability of the rail at the joint, the rail top quenching is carried out in the range of 30-70mm at both ends of the rail, and the qunenching depth is 8-12mm.
The company has more than 20 years of experience in the steel industry, the company operates and sells a variety of types of rail and rail accessories, such as fish plate, tie plate, and rail turnout. The company has formed a strong sales system during its operation.
