advantages  

1. Special heat treatment technology  

Special heat treatment process is adopted to optimize the structure, improve the hardness and enhance the impact resistance of the big gear.  

Long service life  

Forward cast steel uses high strength steel to produce large gear.  Firstly, the characteristics of the rotary kiln are optimized to ensure the stability of the rotary kiln in long time operation and prolong the service life of the rotary kiln.  

3. Factory price customization and fast delivery  

Qianjin cast steel has a strong production capacity of steel castings, and can provide large gear in large quantities and short cycles.  

Big gear (rotary kiln or ball mill) quality inspection:  

● Large ring cast in half ● Non-destructive testing to ensure zero defects ● Multi-step machining gears to ensure the best finish and accuracy ● Final quality inspection to ensure CPG quality
