The coal mill roller cover is an important component of the coal mill. It is assembled with the bearing chock and the grinding roller by the roller shaft bearing. It is sheathed outside the door frame, which is equivalent to the shell. During the maintenance, the roller cover is turned out and the roller is inspected and repaired. The roller cover produced by the Great Wall Steel Casting adopts SCW480 material, which can ensure the strength and toughness of roller cover.

Advantages of CHAENG coal mill roller cover

1. Advanced computer technology
CHAENG uses the casting CAE software to simulate the gradual solidification process, which can assist the design and optimization of the process, to prevent shrinkage, cracks and other casting defects, and and meet the requirements of flaw detection.

2. Control the chemical composition strictly
CHAENG has a group of professional technical engineers to do mathematical statistics analysis. The research has found that each element has certain influence on the solidification shrinkage, crack formation and service life of the coal mill roller cover. Therefore, in the smelting process, the elements of the coal mill roller cover are strictly controlled, and the purity of the pouring molten steel is guaranteed.

3. Mature pouring team
After nearly ten years of casting practice, CHAENG pouring team constantly sum up experience and improve themselves in long-term practice. Nowadays, a complete and effective principle has been formed in the process of pouring, that is, to adhere to the principle of low temperature and quick casting, to ensure the rising speed and solidification shrinkage requirements, and to improve the casting quality.

In recent years, relying on superb casting technology, high-quality products, CHAENG attracted a large number of overseas people from Japan, Korea and other countries to visit. A well-known Japanese coal mill manufacturers designated CHAENG to provide all kinds of important parts, such as rollER cover, bearing chock, roller shaft bearings, smash base door frame, etc..
