Barter is the present and the future of international trade, especially for people who is starting in the import export business. Barter and more: Triangular operations.
The central trough used in mine is an important bearing part of the scraper conveyer to transport coal and materials. Coal and materials will act on the central trough to different degrees in the process of transport. Under the long running state, the central trough used in mine will be worn.
The middle slot of the scraper, as the main energy dissipation part, is also a part with large wear. In addition to friction wear and corrosion wear, there are also serious deformation of tank and fracture of connecting members. In the middle trough, the stress condition is more complex, not only to bear all the gravity of coal, gangue, scraper chain and sheeper, but also to bear the working resistance imposed by the walking mechanism when sheeper works. In addition, coal and scraper chain in the middle trough in the process of sliding plate will also produce resistance. Therefore, higher requirements are put forward for the stiffness, strength and wear resistance of the middle slot.
Henan Shuanzhi as the coal machinery industry quality manufacturers, is how to improve the central trough scraper wear resistance? In order to enhance the abrasion resistance of the central trough, our factory selected alloy steel material to manufacture the central trough at the beginning of production, and conducted heat treatment such as tempering and cold rolling to enhance the plasticity, hardness and wear resistance of the material before production and manufacturing. After the groove is formed, the surface in contact with the scraper chain is polished to reduce friction. In addition, the scraper chain and the middle slot are two parts of the interaction, the need for the scraper and the middle slot with good, so in the choice of the middle slot material, also want to refer to the scraper material.
Improving the abrasion resistance of the middle slot of the scraper is of great significance for reducing the malignant accident, prolonging the service life, and improving the working efficiency and reliability of the scraper. Henan Shuanzhi produces all kinds of middle slots. If you need, please contact us.
