DAWSON Mining Chain Production Process

Production process of mining chain:

bar cutting → bending and knitting → joint → welding → primary proof test → heat treatment → secondary proof test → inspection. 

Welding and heat treatment are the key processes in the production of mining round link chain, which directly affect the product quality. Scientific welding parameters can improve the yield and reduce the production cost; appropriate heat treatment process can give full play to the material properties and improve the product quality.
