In daily life, silicon steel sheets are widely used in motor cores. However, the manufacturing of silicon steel sheets can be divided into two aspects: hot rolling and cold rolling. Many friends do not know the differences between hot rolling and cold rolling. Today, the editor will share with you about the differences 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 rolling and cold rolling of silicon steel sheets: different processing effects. When processing silicon steel sheets by shearing or stamping during hot rolling and cold rolling, the response is different, and the effect on the properties of cold-rolled silicon steel sheets is particularly significant, while the effect on hot-rolled silicon steel sheets is relatively small.

We can choose the cold and hot rolling of silicon steel sheets according to our actual situation, but we need to pay attention to the selection of silicon steel sheet manufacturers. We should choose manufacturers with good quality and good service. Do not choose defective silicon steel sheets due to price factors. Good silicon steel sheets not only help us improve work efficiency but also help us improve product quality.
