Grain oriented Electrical (CRGO) steel production workshop
Decarburizing nitriding coating line
Carbon content is controlled below 0.003%, forming a dense, uniform SiO₂ film on the strip surface
Magnesium oxide isolation coating
Prevent the bonding during high-temperature annealin, forms a magnesium silicate glass film layer.,reducing iron loss
High temperature annealing
Carbon content is reduced to below 0.003% (30 ppm) to eliminate magnetic aging and form a dense, uniform silicon dioxide surface film
Finishing slitting line
Edge trimming and removal of surface defects. The weight of each roll is controlled to be within 4.5T, ensuring uniformity of the entire roll’s grade.
