In industrial production, abrasion, high temperatures, and chemical corrosion often shorten equipment lifespan and hinder efficiency. The alumina lining plate—made from high-purity Al₂O₃ and sintered at over 1700°C—solves these pain points. With a Rockwell hardness of 80-90 HRA and wear resistance 266 times that of manganese steel, it has become a staple across critical industries. Below are its core applications and why it’s a wise investment for businesses aiming to cut costs and boost stability.
1. Core Industrial Applications
Alumina lining plates excel in harsh environments, making them indispensable in sectors where equipment endures constant friction, impact, or extreme heat. Here are their top uses:
Thermal Power & Coal Industry
Coal conveyors, pulverizers, and fly ash pipelines in thermal power plants and mines face severe abrasion from coal particles. Traditional metal liners wear out in months, causing costly downtime. Alumina liners extend component lifespan by up to 10 times, enabling years of continuous operation. Their 1700°C high-temperature resistance also suits boiler systems and ash discharge channels.
Steel, Cement & Mining Sectors
In steel production, alumina liners protect blast furnace tapholes, ladles, and converter mouths from molten iron and slag erosion, extending service life by 50%+. For cement plants and mines, they line chutes, crushers, and grinding mills, shielding against ore and clinker impact. Alumina-lined mining pipelines reduce wear drastically, preventing leaks and boosting throughput.
Chemical & Glass Industries
Chemical plants rely on alumina liners for pumps, reaction vessels, and pipelines handling corrosive acids, bases, and slurries. They resist concentrated sulfuric acid and other harsh media, avoiding leaks and product contamination. In glass manufacturing, their 1600°C heat resistance makes them ideal for furnace linings, preserving equipment and ensuring consistent glass quality.
Specialized Uses
Beyond core industries, high-purity (99% Al₂O₃) alumina plates serve in military bulletproof vests (Level 3-6 protection) and armored vehicles—their lightweight design enhances comfort without sacrificing safety. In foundries, they line chutes and crucibles, withstanding molten metal abrasion and stabilizing casting processes.
2. Key Advantages for Your Business
Alumina lining plates deliver tangible value:
- Longevity: Extends equipment life 5-10x vs. traditional materials, cutting replacement costs.
- Cost Savings: Minimizes maintenance downtime and labor expenses.
- Versatility: Resists wear, high temperatures, corrosion, and UV exposure.
- Easy Installation: Available in 6mm-50mm thicknesses and custom shapes (hexagonal, arc), installable via bonding, bolting, or vulcanization.
- Environmental Safety: Reduces material leakage and waste.
