The main purpose of wear-resistant steel plate:
1) Construction machinery and equipment: mining dump trucks, loaders, bulldozers, excavators, bucket plates, side blades, bucket bottom plates, blades, and counter plates.
2) Loading and unloading mechanical equipment: unloading rolling mill chain plate, hopper liner, grab blade plate, medium-sized automatic dumper bucket plate, stacker and reclaimer bucket wheel plate.
3) Construction machinery and equipment: cement pusher tooth plate, concrete mixer liner, mixing floor liner, dust collector liner
4) Metallurgical machinery and equipment: iron ore sintering conveyor elbow, iron ore sintering machine liner, scraper conveyor liner
5) Mining machinery and equipment: linings and blades of mineral and stone crushers.
6) Other mechanical equipment: sand mill barrel, blade, various port machinery wear-resistant parts
7) Thermal power equipment: coal pulverizer liner, coal hopper, coal distribution pipe, coal distributor grating, coal unloading equipment liner, bulk removal machine.
8) Shot blasting machinery and equipment: shot blasting machine liner
The main grades of wear-resistant steel areNM300,NM360, NM400, NM450, NM500, NM550, NM600. We can supply wear-resistant steel with a maximum hardness of 600HBW. Excellent performance, straightness and surface quality can strictly meet the requirements. It has high wear resistance, high stability, high hardness, high strength and excellent impact toughness. It can meet the requirements of wear-resistant parts in various industries. Wear-resistant steel plate can be used to manufacture first-class equipment and spare parts, can withstand years of industrial and mining assessment, maximize equipment life, reduce the risk of failure, and increase productivity. Mainly used in equipment wear parts, dump truck compartments, concrete mixers, underground mines, cement industry, road construction industry, mining stone and open pit mines and metallurgical industries and other fields. Can effectively reduce the production cost of enterprises, improve product quality, and enhance the competitive advantage of enterprises. In recent years, it has been widely used in many industries.
