Particles are transported by sliding conveying under the action of gravity, and have been widely used in metallurgy, mining, construction, quarry, wharf ,recycling and many other occasions.
An important technical indicator of sliding conveying equipment is the wear resistance of the surface of the lining plate, which determines the cost and service life of the equipment. At present, the following two methods are traditionally used:
1. Composite plate structure, that is, surfacing cemented carbide as a wear-resistant layer on an ordinary steel plate, this method belongs to the production method of cast cemented carbide, not only the mechanical strength is low, but also due to the limitation of the processing, when the surfacing reaches a certain thickness, tortoise-like cracks will inevitably occur, and the cemented carbide layer will fall off quickly under the scouring action of the material.
2. Inlaid structure, that is, inlaid cemented carbide blocks on ordinary steel plates. Densely arranged, and hard spots are formed on the surface of the lining plate to achieve the purpose of wear resistance. But due to structural limitations, the utilization rate of cemented carbide is low. Although the dense arrangement of the hard points can improve the wear resistance, the strength of the parent body will be greatly reduced. Under the scouring action of the material, the parent body will be quickly worn away, resulting in the damage of the entire lining plate.
So, what is the best proven method to solve the problem?
Sintered cemented carbide has been proven to be the most wear-resistant material due to its high hardness and high strength. Welding cemented carbide to steel to make it a long-life wear liner is currently the most economical way. The service life of the liner is greatly improved, and the number of replacements of the liner is reduced, thereby greatly saving labor costs and increasing production.
The carbide chute liner Plates produced by Zhuzhou Old Craftsman after years of research and development and testing adopt specially developed cemented carbide grades. Through overpressure sintering of cemented carbide, vacuum welding, and special post-processing, the service life of the product is increased to dozens of times than the current traditional materials. Truly high quality and cost-effective.
