Cold rolling mill is a kind of mechanical equipment for rolling metal steel coils, which can be divided into stainless steel cold rolling mill, carbon steel cold rolling mill, copper coil mill and aluminum coil cold rolling mill, etc. However, no matter what kind of cold rolling mill, the quality of the main frame is very important, because it is an important part for carrying rolling. If the main frame has low accuracy, or even deformation, it will directly affect the quality of rolling, and even may cause it can not be used normally. So we suggest that the main frame should be placed for a period of time before finishing, This will play a positive role in the subsequent processing and use.

Why is it necessary to place the main frame of the cold rolling mill for a period of time? This is mainly to remove the organizational residual stress in the metal components of the frame. In some countries, the relevant components will be left standing for one year, so that the internal stress of the main frame can be released after the changes of the four seasons, and can also be adapted to different temperatures and seasons, so that there will be no obvious deformation in later use.

If the supplier tells you that you need to wait for a period of time when you purchase a cold rolling mill, how long will you wait? I will be there for one year. After all, stable production is very important.
