The process generally used for wear-resistant liners includes cutting, processing, assembly, welding, quality inspection and surface treatment. Specifically:
Material preparation: Wear-resistant liners are usually made of high strength wear-resistant steel plate as the base material, with appropriate thickness, size and material of steel plate selected to ensure that the wear-resistant liners have sufficient strength and wear resistance.
Heat treatment: Heat treatment is the key link to improve the performance of wear-resistant liners. Through annealing, normalizing, quenching and tempering processes, the hardness, tensile strength and wear resistance of steel plates can be improved.
Cutting: The steel plate after heat treatment needs to be cut to obtain the required shape and size. Common cutting methods include flame cutting, plasma cutting and laser cutting to ensure that the cutting edge is flat and free of burrs, while controlling the dimensional accuracy.
Processing: the steel plate after cutting needs to be milled, drilled and other processing to ensure the flatness and precision of the processing surface, and prevent the heat generated in the processing process from affecting the performance of the steel plate.
Assembly: the processed steel plate is assembled by bolt connection or welding to ensure a firm connection, good sealing, and control the assembly accuracy.
Welding: If welding is used for assembly, attention should be paid to the control of welding quality and welding speed to ensure that the welding seam is flat and free from defects such as porosity and slag inclusion.
Quality inspection: ultrasonic and magnetic particle testing are required for the quality inspection of wear-resistant liners after manufacturing to ensure that they meet the design and use requirements.
Surface treatment: In order to improve the wear resistance and service life of the wear-resistant liner, it is necessary to carry out surface treatment such as spraying and carburizing quenching, control the treatment temperature and treatment time well, and ensure the uniformity and flatness of the surface treatment.
