摘要：
A PROCESS FOR PRODUCING A SINGLE ORIENTED SILICON STEEL PLATE OR PARTICULARLY A SINGLE ORIENTED SILICON STEEL PLATE HAVING A HIGH MAGNETIC INDUCTION PRODUCED BY ADDING A SMALL AMOUNT OF AL IN THE MOLTEN STEEL CHARACTERIZED BY THAT IN HEATING STEEL PLATE IT IS PAINTED WITH AN ANNEALING SEPARATING AGENT, TO WHICH BORON OR BORON COMPOUND IS ADDED IN A PRESCRIBED AMOUNT, AND THEN FINALLY ANNEALED, WHEREBY THE IRON LOSS CAN BE REMARKABLY REDUCED.
