Abstract
930,497. Making sheets; altering physical properties; cold rolling. YAWATA IRON & STEEL CO. Ltd. Oct. 2, 1959 [Oct. 8, 1958], No. 33570/59. Classes 83 (2) and 83 (4). A method of producing a doubly-oriented silicon steel sheet or strip comprises subjecting a silicon steel sheet containing 2-4% Si; 0.01-0.05% A1 and the rest iron to two steps of cold rolling in two crossing directions, then to an intermediate anneal at a temperature between 850 and 1200 C., then to a final cold rolling in either of the above-mentioned two cold rolling directions with a reduction in thickness of 50-84% and finally box-annealing at a maximum holding temperature of 1000 to 1300 C. for a period of 5 to 40 hours. In an embodiment a hot rolled silicon steel sheet is pickled, cold rolled with a reduction in thickness of 30-60% in one direction, again cold rolled with a reduction 20-50 % in another direction displaced 90 20 degrees with respect to the direction of the first cold rolling then box annealed at a maximum holding temperature of 850 to 1200 C., then finally cold rolled with a reduction of 50-84% in either of the abovementioned two cold rolling directions and box annealed. In another embodiment for producing a doubly-oriented silicon steel strip, the hot rolled silicon steel sheet 3.0 mm. thick is cold rolled with a reduction of 40% in the same direction as that of the hot rolling to produce a cold rolled silicon steel strip 1.8 mm. thick, the strip is cut into sheets of predetermined length and the sheets are welded end to end into a new steel strip whose longitudinal direction is approximately at a right angle to the direction of the cold rolling. The new strip is cold rolled with a reduction of 40% to an intermediate gauge of 1.08 mm., annealed at 800 C. for three minutes in wet hydrogen to effect carbonization followed by a second annealing at the maximum holding temperature of 1100 C. for 10 hours and then cold rolling the strip longitudinally with a reduction of 72% to final gauge and box annealing at 1200 C. for 20 hours. Specification 917,282 is referred to.
