Wear-Resistant Steel Plates: Properties, Industrial Applications and Selection Criteria

Wear-resistant steel plates boast high hardness, excellent wear resistance and strong impact toughness, while also offering customizable machinability and weldability as required. As a core material for replacing conventional steel plates, they effectively reduce equipment wear and maintenance costs and extend service life. These plates are widely applied in industries centered on material conveying, mechanical wear, and ore/powder processing, including metallurgy, mining, building materials, engineering machinery, electric power, coal, port logistics and chemical engineering. Their core application scenarios across various industries are detailed as follows:

1. Mining Industry

Crushing equipment: Liner plates, crushing chambers and hammer bases of jaw crushers, cone crushers and impact crushers.
Conveying/loading equipment: Car body plates of mining trucks, bucket walls of loaders/excavators, middle troughs, chutes and hoppers of scraper conveyors.
Screening equipment: Sieve plates and side plates of vibrating screens.

2. Metallurgical Industry

Suitable for wear scenarios involving high-temperature material conveying, furnace matching and steel rolling auxiliary processes in ferrous and non-ferrous metal smelting, with high temperature resistance required for some applications:

Steelmaking/ironmaking processes: Chutes, hoppers, liner plates of mixers, grate bars of sintering machines, chutes and car bodies of blast furnace charging cars.
Steel rolling processes: Guide guard plates of rolling mills, liner plates of straightening machines and guard plates of conveying roller tables.
Non-ferrous metal smelting: Hoppers matching electrolytic cells and chutes for slag material conveying.

3. Building Materials Industry

Adapted to the grinding, conveying and forming working conditions of powder/granular materials in the production of cement, ceramics, glass and new building materials, catering to the characteristics of fine grinding and continuous wear:

Cement production: Liner plates and mill head plates of ball mills and tube mills, hoppers of bucket elevators, blades of screw conveyors and discharge openings of cement silos.
Ceramic/glass production: Liner plates of raw material mills, chutes for powder conveying and liner plates of feeders.
New building materials: Batching hoppers and conveyor belt liner plates in the production of gypsum boards and aerated concrete blocks.

4. Engineering Machinery Industry

Mainly used for wear-prone structural components of engineering machinery equipment to extend the operational service life of equipment in infrastructure construction, mining and earthmoving engineering:

General engineering equipment: Buckets, bucket tooth seats and track shoes of excavators, loaders and bulldozers.
Specialized equipment: Drill pipe guard plates of rotary drilling rigs, hammer body liner plates of pile drivers, and hoppers and S-pipes of concrete pump trucks.

5. Electric Power Industry

Covering thermal power, hydropower, wind power and other categories, and corely adapted to wear scenarios involving thermal power fuel conveying, hydropower sand and gravel processing and wind power foundation matching:

Thermal power generation: Coal chutes, coal hoppers and scraper conveyor liner plates of coal handling systems; mill discs and roller guard plates of coal mills; slag chutes and slag hoppers of slag discharge systems.
Hydropower generation: Crusher liner plates and chutes of sand and gravel processing systems in hydropower stations, and guard plates for flow-passing components of water turbines.
Wind power generation: Wear-resistant guard plates for wind turbine tower foundations and material protection plates inside wind turbine nacelles.

6. Coal Industry

Suitable for the entire process of coal mining, washing, storage and transportation, and able to withstand the wear characteristics of coal grinding, gangue impact and coal powder conveying:

Coal mining: Guard plates of the cutting unit of shearers, middle troughs of scraper conveyors and chutes of reloading machines.
Coal washing/storage and transportation: Liner plates of jigs and heavy medium cyclones; liner plates of coal silos, coal chutes and guide chutes of belt conveyors; car body plates of coal transport trucks.

Working conditions vary across different industries in terms of impact strength, wear type, operating temperature and exposure to corrosive media, which imposes differentiated requirements on the hardness, wear-resistant layer thickness, base material and composite process of wear-resistant steel plates. For instance, steel plates with a high-toughness base material and a medium-thick wear-resistant layer are ideal for high-impact mining working conditions, while composite wear-resistant steel plates with a stainless steel base material and a wear-resistant layer are suitable for chemical industry scenarios requiring both corrosion and wear resistance.

We can provide professional specification selection suggestions for wear-resistant steel plates across various industries, including the optimal matching of wear-resistant layer hardness and thickness.
