Hand sanding: Use simple tools to remove rust or sand the wear plate. The mechanical polishing rust removal method uses mechanical driving force to remove rust and oxide scale through impact and friction. Shot blasting is a commonly used method in mechanical rust removal. It uses mechanical centrifugation, compressed air or high-pressure water flow as power, Q235C low carbon steel plate sprays sand or steel shot to the surface rust or scale of the composite wear-resistant liner. Rolling and polishing method is to put the workpiece and abrasive into the drum to rotate or vibrate. The application of alloy plate in the steel structure makes the workpiece directly contact and rub against these wear-resistant plates to remove the rust layer or oxide scale.
The density advantage of wear plate It is understood that wear plate is the brighter product type in wear plate. The wear-resistant plate has a large hardness and a wide range of applications, and can be implemented in almost all construction machinery industries.
Good, the direct reason for its wide application is its high density.
The density of the wear plate is higher than that of some materials, which makes its hardness relatively large. The density of commonly used steel for wear-resistant plates is 7.85 kg/cubic dm. Quenching to obtain martensite group tempering. Or temper at 650 and then pass 350-600 at a slow cooling rate.
Or after tempering at 650 and heating for a long time at 350~650, the wear plate will become brittle. If the embrittlement wear-resistant plate is heated to 650, the Q235C low-carbon steel plate is then quickly cooled, and the toughness can be called reversible temper brittleness. The high-temperature temper brittleness is manifested by the increase in the toughness-to-brittle transition temperature of the wear-resistant plate.
The whole process of wear-resistant plate work hardening (1) During the whole process of brittle fracture, the process performance of the metal composite material will also change with the change of the internal structure of the metal composite material. The increase of the independent variable, the expansion of the tensile strength and compressive strength of the metal composite material, and the reduction of plastic deformation and plasticity, this kind of situation is the processing increase.
Work hardening has important practical significance in the production process of gold wear-resistant plate raw materials. Q235C low-carbon steel plate has been widely used to improve the tensile strength of metal materials and polymer materials. The transmission chain of the chain is Q345 (16Mn). The original compressive strength of ferritic stainless steel and alloy plate in steel structure is 150HBW, tensile strength Rm≥520MPa, after five times, the thickness decreases from 3.5 mm to 1.2 mm (the deformation variable is 65.7%). At this moment The compressive strength is increased to 275HBW, and the tensile strength is increased to nearly 1000MPa, which doubles the load working skills of the transmission.
