<p>In the production of grain oriented electrical steel sheet, the control of condition of thin slab continuous casting allows to obtain advantageous solidification structures and precipitates. The steel has an initial content of carbon less than 300 ppm and initial content of acid-soluble aluminium higher than that normally used for said type of steel. During the final steps of said process, the annealed sheet is nitrided through a limited amount of nitrogen. This, in turn, allows to decritize the process for controlling the grain dimensions and to realise a constant-quality product.</p> |
