Abstract (en)
A silicon steel plate excellent in magnetic properties, workability, flatness, punching quality and the like is produced easily even in a case of high Si content as much as 12 wt%, through ÄAÜ powder mixing process using iron powder and Fe-Si alloy powder, ÄBÜ powder rolling process for forming the mixture into sheet metal, ÄCÜ sintering process, ÄDÜ cold rolling process, ÄEÜ diffusion annealing process, and ÄFÜ finish rolling process for subjecting the sintered, cold-rolled and annealed sheet metal to skin pass rolling. <IMAGE>
