Description

technical field [0001] The invention relates to an alloy material, in particular to a surfacing welding alloy material resistant to high temperature abrasive wear. Background technique [0002] We know that vulnerable mechanical parts that work under high temperature conditions, such as the surfacing welding of single rolls, claws and grate plates used in the single roll crusher of the sintering production line of the steel plant, must have high temperature resistance and wear resistance. performance. The academic circles classify the working condition of coexistence of high temperature and wear as "compound wear condition", which is harsh and complicated. This requires that the surfacing material has good performance. Overseas large multinational companies such as Castorin Erteti in Switzerland and Mesa in Germany have their own brands of surfacing materials for high-temperature wear, such as: 6715 surfacing welding produced by Castorin Welding rods and surfacing welding...
