Industrial wear is very complex, it is not possible to use a wear-resistant material to cope with all working conditions, our company according to different wear principles developed a series of wear-resistant products corresponding to different working conditions. Surfacing high wear-resistant products is in the tough, plasticity is very good ordinary low carbon steel or low carbon low alloy steel surface through the surfacing method of composite thickness of a certain thickness of high hardness, excellent wear-resistant wear-resistant layer and made of plate products. When working, by the matrix to provide resistance to external forces of strength, toughness and plasticity and other comprehensive performance, by the wear-resistant layer to resist surface abrasive wear.
Wear-resistant surfacing material series of products, its surface hardness HRC up to 62 ~ 66, adapted to temperatures greater than 800 ℃, from the external form can be divided into four categories:
1, solid core flux skin surfacing material: easy to operate, flexible application;
2, block-shaped self-melting alloy surfacing material: in a larger area of surfacing can be realized when a higher surfacing efficiency;
3, Tubular flux cored surfacing material: high surfacing efficiency, and can achieve lower dilution of the base material, etc.;
4, Large area compound wear-resistant liner: high hardness, good wear resistance, easy to use, can be directly used in a variety of mineral conveying chute.
High-chromium cast iron (HRC50～60), high-chromium boron system (HRC58～65), high-chromium and high-manganese system (HRC18～22), after cold work hardening
(50～55), chromium-molybdenum-tungsten system (HRC55～60)
Thickness of wear-resistant layer: 3～8mm
