The girth gear is the main component of the rotary kiln and ball mill, which drives the entire cylinder to run for a long time. Therefore, in actual production, the quality requirement of the girth gear is high.On the basis of rich manufacturing experience and advanced equipment, CHAENG is able to offer high quality girth gears according to users' drawings and requirements. CHAENG girth gears are widely used in China, and also have been successfully exported to foreign markets.

1. Digital simulation for process optimization
Use CAE software to to digitally simulate the casting process to optimize the casting process and ensure the quality of the girth gear.
2. High strength, abrasion resistance and impact reaiatance:
Carry out quenching and tempering treatment on the girth gear, so that the girth gear has good comprehensive mechanical properties.
3. Long service life:
Use high-strength steel for girth gear casting, and use German OBLF direct reading spectrometer, carbon and sulfur analyzer, and three element analyzer to check the composition of steel.
4. Professional polishing and finishing team and large shot blasting equipment to ensure surface quality.
5. Quality assurance
The fabrication route is governed by the provisions of the implemented Quality System ISO 9001:2015.
The standard documentation ensures the full traceability of every process step, including heat treatment, chemical composition test, mechanical properties test, non-destructive test, and dimensional check.
Before casting, CHAENG numerically simulates the casting process by means of CAE software to analyze the molding process, predict and optimize the process precision.
Base on the requirements of customers, CHAENG selects appropriate wooden mold for modeling design.
Strictly according to the process procedures to produce high-quality girth gear: wood mold - sand moulding - pouring - heat preservation - out of the pit, sand cleaning - heat treatment - finishing - machining - flaw detection - packing and delivery.
We use advanced detection equipment for non-destructive testing to ensure the quality. CHAENG steel castings can meet level-two flaw detection standards.
CHAENG girth gears with excellent product quality are not only sold throughout China, and also have been successfully exported to foreign markets.
CHAENG girth gears are applied to the Xinjiang Tianshan Group, Henan Meng Group, and other well-known domestic and foreign cement enterprises, for the normal operation of ball mill and rotary kiln.
CHAENG customized for the Turkish customers a large girth gear with diameter of 7.3 meters and made up of GS34CrMo4 material, and received customer's high praise.
