In life, silicon steel sheet is widely used in motor core, but the manufacturing of silicon steel sheet is divided into hot rolling and cold rolling. Many friends do not know the difference between hot rolling and cold rolling. Today Xiaobian shares 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 sheet is different from that of hot-rolled silicon steel sheet. The magnetic saturation point of cold-rolled silicon steel sheet is higher, which is about 0.3T higher than that of hot-rolled silicon steel sheet.

The second difference between hot rolling and cold rolling of silicon steel sheet is that the unit loss of cold rolling silicon steel sheet is lower than that of hot rolling silicon steel sheet. Cold-rolled silicon steel sheets are more durable at the same frequency and flux density.

The third difference between hot rolling and cold rolling of silicon steel sheet is that the effect of processing is different。 Shearing or stamping for hot rolling and cold rolling of silicon steel sheets have different reactions, which have obvious influence on the properties of cold rolled silicon steel sheets, but little influence on hot rolled silicon steel sheets。

We can choose the cold-rolled and hot-rolled silicon steel sheets according to our actual situation, but we need to pay attention to the selection of silicon steel sheet manufacturers to select good quality, good service manufacturers, do not choose the residual silicon steel sheets because of price factors, outstanding silicon steel sheets are not only conducive to our improvement of work efficiency but also。 It can help us to improve the quality of our products。
