APPLICATION CASE

Port transportation

Detail：

In the port, iron ore, coal and other bulk handling system, grab hopper, chute and other components subjected to severe wear, the wear-resistant composite steel plate in the worn parts, to extend the service life of wear parts, reduce the downtime of handling machinery is very important.

Because the alloy powder is added to the bath during welding, the heat of the arc is absorbed. The cooling rate of molten bath is accelerated, the crystallization time of liquid metal is shortened, the grain growth is limited, and the grain size of welding layer is fine. Compared with casting, the wear resistance can be increased by several times under the same composition. The alloy composition of surfacing layer is generally carbon content 3%-5% and chromium content is 20%-40%

One of the great advantages of using hardfacing composite steel plate to make liner is that the wear-resistant material is double metal material, the surface is high alloy wear-resistant layer, and the master plate is carbon steel plate. The carbon steel plate has good plasticity and toughness, can bear great impact, and can also be bent. In order to adapt to different working conditions, it can do the bending process. Therefore, this kind of surfacing wear-resistant plate is both wear-resistant and tough. In addition, surfacing wear-resistant plate can also be used plasma cutting machine into different sizes, complex shape of the workpiece, it is very convenient to use.
