Wear-resistant ceramic sheets are a high-performance engineering ceramic material. With its excellent wear resistance, high hardness, and excellent corrosion resistance, it has become a key solution for the industrial field to combat wear. The following is a detailed description of its core performance and application scenarios:
Core performance
Ultra-high hardness and wear resistance: The hardness can reach HRA88-95 (Rockwell hardness), second only to diamond, and more than 10 times that of manganese steel. The wear resistance is 266 times that of manganese steel and 171 times that of high-chromium cast iron, which greatly extends the life of the equipment.
Excellent impact resistance: The toughness is improved through toughening technology (such as zirconium oxide toughening, composite structure), and it can withstand a certain intensity of mechanical impact.
Strong chemical corrosion resistance: Acid and alkali corrosion resistance (except hydrofluoric acid), suitable for corrosive environments such as the chemical industry and wet operations.
Lightweight design: The density is only 3.6-4.2 g/cm³, which is half of that of steel, reducing the load on the equipment.
High bonding strength: Using special adhesives or welding processes, the bonding strength with the metal matrix is ≥30 MPa, and it is not easy to fall off.
Application scenarios:
Mining and cement industry: chutes, fan impellers, powder selector blades, mill linings, conveying pipelines. Resist erosion and wear of high-hardness materials such as quartz sand and slag, and extend the life of equipment by 5-8 times.
Low friction coefficient: The surface is smooth, reducing material flow resistance and energy consumption.
Power industry (coal-fired power plants): coal conveyors, coal mill outlet pipes, dust collectors, fan volutes, solve the erosion and wear of coal powder particles on the pipe wall, and reduce the frequency of shutdown and maintenance.
Iron and steel metallurgical industry: blast furnace coal injection pipes, sintering machine hoppers, dust removal pipes, coking guide troughs. Resist the wear of high-temperature dust and metal particles, and replace traditional cast stone liners.
Chemical and coal washing: cyclone linings, flotation tanks, mixing tanks, slurry conveying pipelines. Resist the combined wear and corrosion conditions of acid-base media and ore slurry.
Engineering machinery: ceramic linings of engineering machinery, pump truck pipelines can extend the service life by 5-10 times.
Port: Lining of the ship unloader hopper and pneumatic conveying pipeline equipment to reduce the friction loss of ore and other materials on equipment.
Selection suggestions
High impact working conditions: Choose toughened alumina ceramics (such as ZrO₂ toughened) or composite ceramic steel plates.
High temperature environment (＞200℃): Welding installation is preferred, or inorganic adhesives are used.
Corrosive environment: Ensure that the purity of the ceramic is ＞95% to avoid chemical erosion caused by impurities.
Product highlights
Wear-resistant ceramic sheets not only have excellent performance, but also have the following comprehensive advantages:
Economic: Long-term use costs are lower than traditional materials, reducing spare parts replacement and maintenance expenses.
Environmental protection: Long-life design reduces resource consumption and carbon emissions.
Customization support: Size (10mm×10mm to 100mm×100mm) and thickness (5mm-50mm), suitable for different equipment
Wear-resistant ceramic sheets have become the preferred protective material in heavy wear industries by significantly reducing equipment wear rate and downtime. In actual applications, the ceramic thickness (commonly used 5-50mm), size, and installation process need to be customized according to the working conditions to maximize economic benefits.
