Preventive measures for cutting cracks in wear-resistant plates
(Summary description)The wear-resistant plate has high wear resistance and good impact performance. It can be cut, bent, welded, etc., and can be connected to other structures by welding, plug welding, bolting, etc., which saves time in the maintenance on-site process It is widely used in metallurgy, coal, cement, electricity, glass, mining, building materials, bricks and tiles and other industries. Compared with other materials, it has a high cost performance and has been favored by more and more industries and manufacturers. .

Cutting crack:
Cutting cracks are similar to hydrogen-induced cracks during welding. If the edges of the wear-resistant steel plate are cut, they will appear within 48 hours to several weeks after cutting. Therefore, cutting cracks are delayed cracks. The greater the price and hardness of the wear-resistant steel plate, the larger the cutting cracks will appear.
Cutting crack prevention measures:
Preheating cutting: An effective way to prevent the price of wear-resistant steel plate from cutting cracks is to preheat before cutting. Before flame cutting, the price of wear-resistant steel plate is usually preheated. The preheating temperature mainly depends on the price and quality level and thickness of the wear-resistant steel plate. The preheating method can be carried out by flame burner and electronic heating pad. You can use a heating furnace to heat. In order to determine the preheating effect of the wear-resistant steel plate price, the required temperature should be tested at the heating point.
