NE chain is actually a kind of sleeve roller chain. Compared with ordinary chain, besides the difference in structure, the purpose is also different. NE chain is mainly an important part of ring chain bucket elevator. Vertical lifting of powder and block particles.

    At the same time, the NE chain is also one of the more easily worn parts in the chain bucket elevator, but as long as the material is selected reasonably and the maintenance is sufficient, the service life of the NE chain can still exceed five years, and the operation rate is close to 100 %.

    In order to improve the performance of the NE chain and extend its service life, the selection of its material should be cautious, and you can compare it more.For example, the NE chain made of 35CrMo alloy structural steel has high static strength, impact toughness and high fatigue limit, and has good hardenability and small quenching deformation, which can better solve the problem of low strength of the original pin. , Prone to cause metal fatigue and fracture.

    Secondly, as a kind of high chromium bearing steel, GCr15 is also one of the commonly used materials for NE chains.The comprehensive performance of this material is very good, and it has high hardenability; when it is heat-treated, it can obtain high and uniform hardness, making the NE chain high in contact fatigue strength, while dimensional stability and corrosion resistance are both Very good, can further improve the wear resistance of NE chains.

    Some NE chains are made of 16Mn material, which has higher strength, better toughness and wear resistance than #45 steel, so there is definitely no problem in terms of performance.The NE chain with this material is stamped and formed at one time, so the reliability of the chain is more guaranteed.
