Wear and impact resistant cast lining for industrial use
Wear-resistant linings are mainly used in the following industrial fields and specific scenarios:
I. Mining industry
Application equipment: mine crusher, self-grinding mill/half self-grinding mill, bucket wheel, hopper, feed trough, shovel liner plate, etc.
Function: resist ore crushing, high intensity wear and impact in the transportation process, prolong the service life of equipment.
2. Steel industry
Application equipment: slag discharge tank, feeding tank, return material machine lining plate, mixing bin, balling plate, conveying pipeline, etc.
Function: protect the surface of equipment from high temperature molten metal and ore erosion, reduce material loss.
3. Power industry
Application scenarios: coal conveying system (pipeline, coal drop pipe), slag discharge system, desulfurization/nitrogen removal equipment, high temperature circulating fan, etc.
Function: resistance to wear and high temperature corrosion of high speed flowing media such as coal powder and slag.
Iv. Cement industry
Application equipment: coal mill, vertical mill, cyclone separator, powder machine pipeline, material conveying pipeline, etc.
Function: Reduce the wear in cement raw material grinding and transportation, to ensure continuous production.
V. Coal industry
Application equipment: scraper conveyor, coal mining machine liner, feed trough, hopper, etc.
Function: to deal with the violent scouring and mechanical impact of coal particles.
Chemical industry
Application: corrosive medium conveying pipeline, reactor lining, material mixing equipment, etc.
Function: wear resistance and acid and alkali corrosion resistance, improve the stability of equipment.
Vii. Metallurgical industry
Application equipment: smelting furnace lining, high temperature material transmission equipment, iron material conveying plate, etc.
Function: high temperature resistance (≤800℃) and wear of metal slag.
Viii. Mechanical manufacturing and environmental protection fields
Application equipment: crushing scrap metal equipment, garbage power generation equipment, dust removal system pipeline, etc.
Function: adapt to the wear resistance requirements under complex working conditions and reduce maintenance costs.
The main material of wear-resistant lining
I. High manganese steel series (Mn13/Mn13Cr2)
Material characteristics: has high wear resistance and toughness, especially suitable for crushing, grinding and other occasions with strong impact and wear, is the preferred material for traditional wear-resistant liners.
Application fields: mining machinery, cement equipment, crusher liner and other heavy industry fields.
2. High chromium alloy steel
Material characteristics: carbon content 4~5%, chromium content 25~30%, hardness can reach HRC56~62, combined with high hardness, high strength and high toughness, excellent high temperature performance (≤800℃).
Application fields: railway, mining, high temperature material transmission equipment and other heavy load scenarios.
3. Composite wear-resistant materials
Welded chromium carbide alloy plate
Chromium carbide alloy layer is welded on the surface of ordinary steel plate, which has better wear resistance than high manganese steel. It can be welded or bolted, and is the mainstream material in recent years.
fiber reinforced ceramic composite
Alumina (Al₂O₃) is the main component, with high hardness and corrosion resistance, suitable for powder flushing or corrosive environment, and can be combined with the matrix by welding, bonding or vulcanization process.
