Wear and tear are inevitable in industries dealing with heavy machinery, mining, and manufacturing. Твердосплавные пластины for wear liners offer an exceptional solution to prolong equipment life and enhance efficiency.
Characteristics of Carbide Plates for Wear Liners
Твердосплавные пластины, primarily made from tungsten carbide (WC) or chromium carbide (CrC), are designed to withstand extreme wear conditions. Here’s what makes them exceptional:
- Чрезвычайная твердость: With a Mohs hardness rating of 9+, tungsten carbide plates are nearly as hard as diamonds.
- Высокая износостойкость: These plates can endure abrasive materials like sand, ore, and coal far longer than steel.
- Коррозионная стойкость: Unlike standard steel, carbide plates resist oxidation and chemical exposure, making them ideal for harsh environments.
- Impact Toughness: Some carbide compositions offer increased impact resistance, reducing breakage risks.
- Customizable Composition: Depending on the application, carbide plates can be mixed with different metal powders to enhance specific properties.

5. Agriculture & Forestry
- Используется в plowshares, harvesting equipment, and saw blades.
- Prevents wear from soil, gravel, and vegetation.
How to Choose the Appropriate Carbide Plates for Wear Liners
Выбор правильного твёрдосплавные пластины depends on various factors. Here’s what to consider:
- Состав материала – WC-Co for mining, Cr3C2-NiCr for high temperatures, etc.
- Hardness vs. Toughness – Higher hardness for abrasion resistance, but increased toughness for impact resistance.
- Среда применения – Corrosion resistance needed? High heat? Heavy impact loads?
- Thickness & Size – Thicker plates last longer but may be heavier and costlier.
- Cost vs. Longevity – Higher initial investment often means lower long-term replacement costs.
