High Quality 0.23~0.3mm Thickness 970~1200mm Width Sillicon Steel CRGO For Transformer

    The magnetism, surface quality, filling coefficient and punching properties of cold-rolled silicon steel sheets are better than those of hot-rolled silicon steel sheets, and can be produced in coils, so some countries have stopped producing hot-rolled silicon steel sheets since the 60s.China uses a low-temperature one-time rapid hot rolling at a low temperature of about 900 °C and stacked annealing method under hydrogen protection to manufacture hot-rolled silicon steel sheets, with a high yield and good surface quality and magnetic properties of the finished products.

   The rolling of silicn steel is divided into two processes: hot rolling and cold rolling, and the traditional process of directly producing silicon steel products by hot rolling has been rarely used, mainly for the production of hot rolling and cold rolling, which is called cold-rolled silicon steel products. According to different products, the cold rolling process is divided into multi-stand rolling mill rolling and single-stand rolling, of which single-stand rolling mainly produces oriented silicon steel products.
