Title: Method for producing cube-on-edge oriented silicon steel
Inventor: MILLER ROBERT F
IPC: C21D8/12
Filed: 1983-03-04
Granted: 1989-03-08
Abstract: Process includes hot-rolling, cold-rolling with intermediate annealing, and final texture annealing.  The improvement comprises surface coating the steel with a Mn containing material, so that secondary grain growth is inhibited during subsequent texture annealing.  The Mn-containing material is pref. Mn(NO3)2.  The steel is suitable for transformer core manufacture.

Abstract: This is for method that maintains effect of crystallization for long by elevating crystallization speed without adding other materials after melting. The treating condition is as follows; melting point +10 < shearing temp. < melting point +100, and 10 < shearing speed (1/sec) < 10,000, and 0.1 < treating time (sec) < 1,000. The temp. of shearing is higher 20-50 deg.C than melting temp., and speed of shearing is 500-5,000/sec.
