  Requirements for the use of zinc pot sink rolls , stabilizer rolls, and shaft sleeve materials in galvanizing production lines Galvanizing production line: The shaft sleeve and bearing bush are installed between the sink rolls and the stabilizer roll to protect the shaft head and the inner hole of the boom from corrosion and wear in the zinc liquid.   According to our domestic on-site inspection and understanding, the shaft sleeve and bearing bush have a short service cycle and a large amount of wear (8-15 days) during the production process. Jumping, the strip is easy to deviate, affecting the quality of the product, causing the shutdown to be replaced during normal production. At present, our company has developed and produced tungsten-based alloys, cobalt-based alloys, tungsten-cobalt alloys, JFE-30A2K3, JFE-30A2K3 with strong wear resistance and high resistance to zinc liquid corrosion according to the use of on-site bushings and bearing bushes to meet market demand. ...

  Repair method of polymer composite material for sink rolls bearing wear   The bearing position of sink rolls has super adhesion, excellent compressive strength, wear resistance and corrosion resistance and other comprehensive properties. It adopts Meijiahua-Fushilan 2211F polymer composite material, which can be repaired without disassembly on site when the wear size of the transmission part is relatively small. It not only avoids the machining of sink rolls, but also has no thermal stress of repair welding, and the repair thickness is not limited. At the same time, the wear resistance of sink rolls products and the concessionality that metal materials do not have, ensure 100% contact fit of the repaired parts, reduce the shock and vibration of the equipment, avoid the possibility of wear, and greatly extend the equipment parts (including bearings) It can save a lot of downtime for enterprises and create huge economic value. Cold welding repair method: The cold welding mac...
