As you know, the cold rolling mill is a project equipment with a large investment. If the cold rolling mill fails to work during operation or after shutdown, it is not a trivial matter for the cold rolling work. The impact is relatively large. After all, if the input is large and the output is affected, the result is not small. How should we deal with it?

First of all, we need to check whether the cold rolling mill does not work due to mechanical failure, such as whether the bearings of some key parts are broken, whether the gears can work normally, etc., but this probability is very low, because the mechanical parts of the cold rolling mill are generally processed with relatively precision, and are also cautious in materials, so generally, this kind of situation will not occur under normal circumstances.

In addition, we need to check whether the data communication between equipment parts is caused by poor data communication, because the communication of cold rolling mill is very complicated. If the communication of one part is different, it may lead to poor communication of the whole system, which may lead to non-operation, just as it is impossible to determine whether it can be started, so we should simply not start. At this time, we need to check whether the operation of each part is normal, Whether the circuit is normal, because the program will not be changed generally, so you can know the result by looking at the surface.

Finally, it is necessary to check whether there is any interference due to the reason. There are many switches of the cold rolling mill, and whether there are some switches that have been closed by human misoperation. Because we only start the switches outside the electric control cabinet at ordinary times, and the internal switches generally do not need to be operated. If the internal switch position changes, then the cold rolling mill will not work, after all, the switches are closed.

For the situation that the cold rolling mill does not work, what other technical points do you know? Let's learn and exchange together.
