The roller material is mainly composed of Cr, Mo, V, W, Nb and other elements. The wear-resistant layer is placed on the outermost layer of the roller sleeve by centrifugal casting. The surface pattern is formed by casting.
The roller base material is mainly alloy steel + titanium carbide/tungsten carbide (stud), and the surface is welded with welding wire to form a wear-resistant layer.
Alloy stud surfacing welding roller is composed of roller shaft, special alloy compound roller sleeve and wear-resistant cemented carbide studs.The extrusion roller of alloy stud surfacing roller press has the following characteristics:
1. The base metal is high-strength and high-toughness alloy cast steel, which can be welded;
2. The corresponding alloy studs can be selected according to the working conditions. The wear resistance of the alloy studs is good, comparable to that of ceramets, and can be welded;
3. In case of peeling of alloy studs under abnormal conditions, the studs can be replanted by overlaying, which is convenient and fast;
4. The alloy stud forms a binding effect in the inlay welding structure, further improving the resistance of the alloy stud and the surfacing layer Abrasion and reliability;
5. The surface of grinding roller has good peeling resistance and integrity; The integrity of the roll surface can be guaranteed when foreign matters enter, Quickly restore size.
The vertical mill roller is designed according to the working conditions and the wear resistance curve of the product. Powder metallurgy technology is used to add studs (material:titanium carbide/tungsten carbide) in the wear area combined with surfacing technology, special welding materials are used to form inlaid welding structure and metallurgical combination to improve product wear resistance Sex and service life, and achieve regenerative repair to improve product life. These rollers are suitable for extreme Under harsh working conditions, it can replace ceramic rollers currently on the market.
