Three Different Times of Wear-resisting Casting Wear and Energy-saving and Environment-friendly Production

The wear of wear-resistant castings is divided into three periods. The first period is the first period, which is the running-in period. For new assemblies, the surface has roughness and geometrical deviations, the actual contact area between fittings is small, and the load per unit area is large. The oil film is not easy to maintain and the wear is strong. After running-in according to the running-in specification, the surface condition enters a condition suitable for the working condition and the wear speed is reduced.


The second period of wear of wear-resistant castings is the period of steady wear. In this case, the wear-resistance of wear-resistant castings increases in direct proportion to the working time, and it generally appears to be slow. However, when the use and maintenance are not careful, and the working conditions are relatively poor, the intensity of wear of the accessories may still be relatively large.


The third period of wear of the wear-resistant castings is the period of heavy wear. The wear-resistance of the wear-resistant castings is relatively large, the gap between the fittings increases, the impact load increases, the lubricant film is difficult to form, and the fittings accelerate wear and should be promptly repaired or replaced. After that, when it comes to energy saving and environmentally friendly production methods for wear-resistant castings, this time, it will also adopt rapid melting technology, replace the rapid melting furnace, increase the thickness of the lining by increasing the number of induction coils, expand the volume of the furnace, and speed up the smelting speed. Reduce heat loss and achieve energy savings.


For energy-saving and environment-friendly production of wear-resistant castings, this time, it will adopt a bell-type resistance furnace with no door-to-door sealing and full-fiber insulation lining, which will increase the heat treatment furnace and sealability and heat preservation effect. At the same time, the entire furnace will be used. The automatic PIC control automatically adjusts the operating power of the furnace throughout the heat treatment process, so that the heat treatment furnace is in the best working condition and energy waste is reduced.


The energy-saving and environment-friendly production of wear-resistant castings means that energy-saving transformers must be replaced. In this case, the power of the transformer will also be increased. This will better match the melting furnace in different production processes. The voltage requirements for the phase, and in this respect, are to a large extent the energy savings that can be achieved in the smelting process.http://www.pump-casting.com/
