Service Available in Warranty Period
- Juneng commits that all of the spring products are of high quality and manufactured basing on drawings. A series of strict inspection ensures that the pass rate is near 100%
- Raw steel materials: we adopt 60Si2MnA instead of 60Si2Mn to realize excellent hardenability, fatigue strength, and mechanical properties of the springs
- Coke oven strips are made from Q345 (16Mn) round steels from Anshan Iron and Steel Group
- Coke oven column and non-standard welded structural: instead of using wide flat steels, we use steel plates from Shougang, Tangshan Iron & Steel, Baosteel, Hebei Wenfeng Iron & Steel Group, and Hebei Jingye Group, firmly ensuring the flatness of plates and the materials' mechanical performance
- Operated correctly, our springs can be used for over 30 years
- Each spring must be given hot setting and sand blasting treatment, as well as load test to guarantee their service life and fatigue strength. For spring load test, we utilize the computer-controlled spring testing machine whose moving testing precision is up to 0.01mm. Besides, this this machine can save the force/displacement curve of each spring, for the convenient of adjusting the coke oven.
- H-beam steel auto-welding machine and 60A and H-beam flange straightening machine is employed in our spring production line. The whole production process is under the supervision of engineers.
