The chain is used in the paper industry. The chain material is made of high-quality alloy steel. The chain plate and pin shaft are made of high-quality medium carbon alloy steel. After overall heat treatment, the chain has high tensile strength and wear resistance. In the process of use, the elongation and fracture of the chain are avoided. And the chain has ultra-high wear resistance, and can be used for a long time without wear,

High precision bearings are used on both sides of the chain, which can withstand the impact force from the paper roll, reduce the friction coefficient of the chain operation, reduce the bearing capacity of the chain operation, and have the characteristics of silence.

The top plate of chain is made of high-quality alloy steel. Through medium frequency heating, the forming angle of each top plate is consistent, which avoids the phenomenon of inconsistent bearing force of paper roll caused by the inconsistent angle of the top plate. At the same time, the whole heat treatment process is adopted to strengthen the strength of the top plate, which has the characteristics of no deformation and no cracking in the long-term operation of the chain.

The chain welding roof adopts robot automatic welding, which ensures the consistency of size, strength and permeability of each weld.

The surface of the chain top plate is sprayed with plastic, and the color of the top plate is bright and beautiful. It also has good anti rust function. The top spraying line in China is used for surface spraying. The hardness and adhesion of spraying plastic are high, and the phenomenon of spraying plastic falling off will not occur after long-term friction use.
