1. Unique heat treatment technology to improve wear resistance. The large girth gear produced by CHAENG adopts unique heat treatment technology in casting, which optimizes the girth gear structure, improves the hardness, and greatly enhances the wear resistance and impact resistance of the product.

2.High-strength steel guarantees the service life of the product. CHAENG uses high-strength steel for girth gear casting, and optimizes the transmission characteristics of rotary kiln and ball mill to ensure the stability of components under long-term operation and prolong the service life of components.

3.Mass production is more efficient. CHAENG has strong production capacity of steel castings, which can produce large quantities of components such as large girth gear with short casting cycle and large output.

As a large-scale steel casting manufacturer in the north of Henan Province, CHAENG has been following the national standard 2 level flaw detection standard and implemented 360° non-destructive testing system. There are German OBLF GS-1000 direct reading spectrometer, carbon sulfur analyzer, three element analyzer, Mechanical performance testing machine, impact test low temperature tank, impact testing machine, UT, MT flaw detection equipment, etc., the purpose is to achieve accurate ratio of chemical composition of cast steel to ensure the quality of steel castings.
