On conveyors, welded rings are used as flat rings and forged rings as vertical rings. The outer width of forging ring is smaller than that of welding ring, the section of straight arm is rectangle with four fillets, and the section of top arc is circle. So forging ring is actually a kind of variable section chain link. The size of welding ring is one specification grade larger than that of traditional ring chain, so the power of conveyor can be upgraded and the conveying capacity of conveyor can be improved without changing the size of conveying chute. At the same time, because the straight arm part of the forged vertical ring contacts with the middle plate of the conveyor chute, the contact characteristics of the traditional ring chain line are changed and the wear resistance is increased.
The "compact chain" has the excellent characteristics that the traditional mining ring chain does not have. Because of this characteristic, some large coal enterprises at home and abroad have gradually used the compact chain on the conveyor. We believe that in the near future, compact chain will be widely used. We should always pay attention to the development of mining chain, including new materials, new processes, new technologies and new production equipment. Only in this way can we keep up with the development of the times. Otherwise, we will lag behind other competitors in the same industry and face the danger of being washed out by the market. If we can speed up the research and development of mining high strength compact chain at this time, it is not too late, or it can be said to be just in time.
