Product Description

Product Description

Custom Transmission Casting Girth Gear Large Ring Gear

The casting ring gear is one of the core components of the rotary kiln transmission system in industries such as cement and metallurgy. It transmits power to the rotary kiln body by meshing with the gear of the drive device to ensure its smooth rotation. The casting gear ring is usually made of high-strength alloy steel and can withstand high temperature and heavy load working environment. Good design and manufacturing process ensure the reliability and durability of the gear ring in long-term operation, which is of great significance for improving production efficiency and reducing maintenance costs.

Production process

Design and mold manufacturing:Product design is carried out according to the drawings and technical requirements provided by the customer.
Make wooden or metal molds for subsequent sand molds or other types of molding

Melting and pouring:

The selected metal material is placed in an electric furnace or cupola for melting.

The mold is preheated before pouring to reduce the temperature difference.

The molten metal is poured into the prepared mold.

Cleaning and polishing:

Remove attachments such as sand, oxide scale, etc. on the surface of the casting.

Polish the surface of the casting to make it smooth and reach the designed size.

Heat treatment:

Finishing:

Perform heat treatment processes such as quenching and tempering to increase the hardness and wear resistance of the gear ring and improve its mechanical properties.

Roughing, semi-finishing and finishing of gears to ensure accurate tooth shape.

 Including turning, hobbing, shaping, grinding and other processes.

Testing and Inspection:

Check the quality of castings, including dimensional accuracy, surface quality, hardness testing, flaw detection, etc.We have also introduced the German imported Spike spectrometer for testing to fundamentally ensure the quality of the product

Company Profile

Who We Are

Established in 2002, Luoyang Wangli Heavy Machinery Co.,ltd. focus on metal research and mining machinery spare parts. Our factory located in Luoyang, one of important base for heavy machinery in China. 2 factories over an area of 13,300 square meters, based on 100+ sets of equipment, our production capacity reaches 12000 Tons/Year. has passed ISO 9001 quality managment system certification in 2015.

Our mainly products: dragline excavator spare parts,rotary kiln spare parts, large modulus gear (gear shaft), gearbox ect. 40+ patents with over 45 years experience to help focus on improve the service life of spare parts. We belive that more than 80% reason of mechanical parts' working life depends on hot processing (steel making/forging/casting/welding/heat treatment). Eight material engineers will control the quality from the original resource.
 
Over the past 15+ export experience, we have served 200+ compaies in 50+ countries and regions, During these times, three international key projects, such as segment girth gear used in the Suez Canal in Egypt.

We believe that innovation is the key to success and attracts talents who can think differently. Together, we can make a real difference.
