Chemshun Dovetail wear-resistant ceramic lining is a wear-resistant lining fixed to the surface of the equipment through a dovetail structure. It is mainly used to prevent internal wear of the equipment. Its design achieves firm mechanical fixation through the clamping of the dovetail guide rail and the ceramic lining
1) Structural features
Dovetail design: stable installation through clamping, fits the surface contour of the equipment, reduces stress concentration, and adapts to complex working conditions such as high temperature vibration
Ceramic material: mainly alumina ceramic, high hardness (HRA ≥ 82), strong wear resistance, high temperature resistance (about 750 ° C), corrosion resistance
2) Advantages
High wear resistance: Made of high-purity aluminum oxide silicon nitride and other raw materials, it has high hardness and strong wear resistance
Corrosion resistance: It can resist the erosion of chemical substances such as acids, alkalis and salts, and is suitable for corrosive environments
High temperature resistance: It can operate stably for a long time in a high temperature environment, and will not soften or deform due to high temperature
Arc design: It adapts to thermal deformation and vibration during equipment operation, reduces stress concentration, and prolongs service life
Long life: Ceramic materials have excellent wear resistance and corrosion resistance, can operate stably for a long time, and reduce the frequency of replacement
Customization: Ceramics of different thicknesses can be selected according to wear conditions, and various special-shaped structure equipment can be customized to form an impact-resistant wear-resistant layer
Easy to maintain: The dovetail groove design makes the installation and removal of the liner more convenient, which is convenient for equipment maintenance and repair
3) Application scenarios
Industrial wear-resistant field: Arc groove ceramic sheets are often used in equipment in mining, cement, power and other industries, such as mill conveyor belt fans, etc. As wear-resistant parts, they can withstand harsh working conditions such as high-speed rotation, high load and high wear
High temperature environment: The arc design enables it to better adapt to thermal deformation during equipment operation, and has excellent high temperature resistance, suitable for high temperature environments above 700℃
Special working conditions: Suitable for working conditions with fast material flow and high impact, such as coal powder conveying pipelines in the thermal power industry, ore crushing equipment in the mining industry, etc.
4) Precautions for use
Installation accuracy: The installation of dovetail groove lining needs to ensure the straightness and spacing of the guide rail, ensure the uniform gap between the ceramic plates, and avoid stress concentration caused by improper installation
Welding quality: Welding installation needs to ensure welding quality to avoid lining falling off or cracking caused by welding defects
Adhesive selection: Adhesive installation needs to select high temperature and aging resistant adhesives to ensure the bonding strength of the lining in high temperature environment
Regular inspection: Regularly check the wear of the lining, replace the severely worn lining in time, and avoid equipment damage caused by lining wear
Cleaning and maintenance: Keep the surface of the equipment clean to avoid wear and corrosion of the lining by impurities and dirt
