Development of wear-resistant middle groove of high-strength heavy-duty scraper conveyor
Due to the frequent use of scraper conveyors in extreme environments, the wear of the middle groove is severe. Through comprehensive analysis, there are three main causes of the middle groove of the conveyor to wear quickly: extreme environments, the abrasive material is conveyed, and the structural design is not appropriate. In order to solve this problem, a piece of wear-resistant middle groove of high-strength heavy-duty scraper conveyor is designed and developed.
Design of Wear-Resistant Middle Groove
1. The size of the middle groove
Based on the scraper characteristics, the design and installation of the middle groove should be appropriate, and the size of the middle groove should be determined according to the corresponding requirements. If the size is too large, the material will accumulate and the material cannot be moved. If the size is too small, the material cannot be discharged smoothly. The size of the wear-resistant middle groove should meet the requirements of the conveyor, and the height and width of the middle groove should be determined according to the size of the head driven shaft and the material to be conveyed, so as to ensure the wear-resistant middle groove works normally.
2. Surface treatment
The wear-resistant middle groove can be treated by surface hardening or nitriding. The nitrided wear-resistant middle groove has a higher wear resistance than the surface-hardened wear-resistant middle groove. The nitriding process temperature is slightly lower than the surface hardening temperature, and the cooling rate is very fast. The quenching effect is uniform and the wear of the hardened layer is very small. At the same time, the nitrided wear-resistant middle groove has a stronger anti-fatigue crack resistance, which can increase the service life of the conveyor.
3. Materials selection
In order to increase the wear resistance of the medium groove, materials with higher wear resistance should be selected. The most commonly used wear-resistant materials are heat-treated alloy steels and wear-resistant shielding materials. The heat-treated alloy steel has high strength, good wear resistance and high impact toughness, while the wear-resistant shielding material has higher wear resistance than the heat-treated alloy steel, so it is an ideal material for the wear-resistant middle groove.
Application of Wear-Resistant Middle Groove
The wear-resistant middle groove is mainly used in the middle groove of high-strength heavy-duty scraper conveyors. The wear-resistant middle groove is designed and produced by considering the wear resistance of the middle groove and the bearing capacity of the conveyor. With the wear-resistant middle groove, the conveyor has a long service life and can be more stable in operation.
The wear-resistant middle groove of high-strength heavy-duty scraper conveyor has been successfully developed. By considering the size of the middle groove, the processing technology and the material selection, the wear-resistant middle groove can effectively improve the wear resistance of the conveyor, thus ensuring the normal operation of the conveyor.
