The most material of grinding roller is high Chrome,add the surfacing welding can extend lifetime and reduce costs and improve efficiency.Surfacing welding include Welding wire hard facing and Alloy studs inlaid surfacing welding.
Welding wire surfacing grinding roller improves the wear resistance and service life by surfacing wear-resistant welding wire on the surface of the roller body.
The Alloy studs inlaid surfacing welding vertical grinding roller is designed according to the working conditions and the wear resistance curve of the product. In the wear area, the powder metallurgy technology and surfacing technology are combined, and the special welding materials are used to form the inlay welding structure and metallurgical combination, improve the wear resistance and service life of the product, and achieve the regenerative repair to improve the service life of the product. This type of roller is suitable for extremely severe working conditions and can replace the ceramic roller and other products on the current market.
We can not only provide users with reliable wear-resistant spare parts for vertical grinding and casting, but also have a professional surfacing team with excellent technology and rich experience. They can be operated on-line and off-line, and can provide users with satisfactory secondary welding.

Feature:
We use proper alloying and and related technological measures to make the blow bars’ surface hardness reaches more than 58HRC , during the process of wearing will maintain high hardness and high wear resistance.
Technology process
In blow bars’ working part we use the technique of directional solidification to make Cr7C3 type carbide is perpendicular to the part.The macro-hardness and micro hardness of carbide can be improved without reducing thoghness.
Application
Suitable for making wearable spare parts with lower impact load and simpler shape.

Feature
The alloy structure cast steel is an iron-carbon alloy formed by adding an appropriate amount of one or more alloy elements on the basis of ordinary carbon steel.
Process technology
According to the different elements added, with appropriate smelting and heat treatment process to obtain high strength, high toughness, high wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, non-magnetic and other related special properties.
Scope of application
It is suitable for producing the wear-resisting spare parts with good mechanical strength and good toughness that are required for various working conditions, and the main steel structure castings with the required dynamic load.
