Abstract
Fe alloy containing Si more than 4.0 wt % is produced by a thin plate casting process. The producing condition depends upon rapid solidification of Fe alloy from a molten condition at cooling rate of more than 1.degree. C./sen to less than 10.sup.5 .degree. C./sec. The obtained thin cast plates are subjected to a hot rolling of more than 30% at the temperature range of 600.degree. to 800.degree. C., and to the cold rolling to a determined thickness, followed pickling. By the above mentioned conditions, operations of the industrial scale may be practiced without cracks on the surface in the cold rolling excellent magnetic characteristics may be provided by passing the annealing after the cold rolling.
