Heat Treatment Round Link Chain Improve Yield Reduce Production Cost

Round link chain,Its material is 25MnV or 23MnCrNiMo54,used in the Submerged Scraper Conveyor:

Production process:

The blanking - cold bending braided - shut - welding - a correction - heat treatment - the second correction (pre) - inspection. Welding and heat treatment is the key to the production of mining circle chain process, directly affects the quality of the product. The welding parameters of science, can improve the yield and reduce the production cost; Appropriate heat treatment process, can give full play to the material performance, improve product quality.

In order to ensure welding quality of the mine ring chain, manual electric arc welding and butt welding have been eliminated, flash butt welding due to the high degree of automation, low labor strength, stable product quality and other prominent advantages, is widely used.

Company's main products:

Drum type ash cooler, bucket conveyor, bucket elevator, embedded scraper conveyor, scraper slag conveyor, dry type slag conveyor, hydraulic shut-off gate, single roller slag crusher, steel ash bin, slag bin, de-watering bin, electric feeder, wetting mixer, dry type bulk loader, pressure relief valve, dense phase pneumatic ash conveying system, dilute phase pneumatic ash conveying system, coal ash separation system, pneumatic double gate valve, pneumatic swing valve, cone pump, material seal pump, coal ash separator, cyclone collector, wear-resistant ceramic elbow, tee joints, and various valves.

Adhering to the "first-class design, first-class products, first-class service" principle, the after-sale service department of the company can provide excellent pre-sale service, sales service and after-sale service to the customers.

1. Pre-sale service: dealing with various consultations and questions, and sending professional technical personnel to do on-site investigation to provide preliminary design plan and reasonable suggestions.
