For the cold rolling mill, the role of the thickness gauge is very important. Without this equipment, it is impossible to accurately know the thickness of the rolled steel coil. However, the internal components of the thickness gauge are relatively precise and sensitive, and a little carelessness may cause the equipment to be unable to operate normally. One of the common problems is the failure of the thickness gauge at high temperature. How to deal with this situation?

When the thickness gauge of the cold rolling mill encounters a high temperature fault, it is necessary to check whether the cooling device of the thickness gauge operates normally. If there is no problem with the cooling device, it is necessary to check whether it is a problem of the ventilation duct, because many hoods are easily blocked by dust, which will lead to poor ventilation, resulting in reduced cooling effect and increased temperature, which is a problem that many enterprises have not noticed, There is no need to buy a new one whenever it breaks down.

Cooling is a very important work for cold rolling mill. Both the thickness gauge and the unit itself need good cooling, so that they can be used for a longer time.
