In daily life, silicon steel sheets are widely used in motor cores. However, in terms of manufacturing silicon steel sheets, there are two aspects: hot rolling and cold rolling. Many friends do not know the difference between hot rolling and cold rolling. Today, the editor will share with us about the difference between hot rolling and cold rolling.

One of the differences between hot-rolled and cold-rolled silicon steel sheets is that the magnetic saturation point of cold-rolled silicon steel sheets is different from that of hot-rolled silicon steel sheets. The magnetic saturation point of cold-rolled silicon steel sheets is higher, approximately 0.3T higher than that of hot-rolled silicon steel sheets.

The second difference between hot-rolled and cold-rolled silicon steel sheets is that cold-rolled silicon steel sheets have lower unit losses than hot-rolled silicon steel sheets. Cold rolled silicon steel sheets are more practical at the same frequency and magnetic flux density.

The third difference between hot-rolled and cold-rolled silicon steel sheets is that the processing effect is affected differently. When processing silicon steel sheets by shearing or stamping during hot rolling and cold rolling, the reactions are different, and the impact on the properties of cold-rolled silicon steel sheets is particularly significant, while the impact on hot-rolled silicon steel sheets is relatively small.

We can choose cold-rolled and hot-rolled silicon steel sheets according to our actual situation, but we need to pay attention to selecting manufacturers with good quality and service. Do not choose inferior silicon steel sheets due to price factors. Outstanding silicon steel sheets not only help us improve work efficiency, but also help us improve product quality.
