What should you pay attention to when processing the ball mill trunnion?

Casting is one of the basic crafts of the modern machinery manufacturing industry. With the increasing demand for large steel castings by major heavy industrial enterprises, the foundry industry has developed rapidly and the number of foundry manufacturers in the market is increasing.

The large demand for steel castings has caused the prices of raw materials used by large steel casting manufacturers to continue to rise, and some raw materials have risen by as much as 10%-20%. At present, some small cast steel mills, in the processing of steel castings, in order to reduce the price, made changes in the raw materials, resulting in poor quality of steel castings, seriously affecting the normal use of equipment.

Taking the ball mill trunnion as an example, if the casting raw material does not meet the requirements or the casting process is not rigorous, after a period of wear, the ball mill trunnion will be cracked or even broken, and the work efficiency will be affected during maintenance. So what details should you pay attention to when casting ball mill trunnion?

Firstly, the rounded corner of the end plate of the hollow shaft of the ball mill is a stress concentration part, and defects such as blisters, pores and cracks are likely to occur at the time of casting, so that defects such as pores and blisters cannot occur in this part.

Secondly, in the processing, the part that is in contact with the spherical tile needs to be ground after processing to ensure accuracy and smoothness.

When processing the steel castings, CHAENG is made of a unique heat treatment technology and high-strength steel for the ball mill trunnion of the user with high cost performance. It strictly follows the national standard 2 inspection standard and implements the 360° non-destructive testing system to ensure the final The steel castings are reliable in quality and long in use.
