METHOD OF PRODUCING (110)001 GRAIN ORIENTED ELECTRICAL STEEL USING STRIP CASTING

摘要

In a method of producing a strip suitable for further processing to yield a(110)[001] grain oriented electrical steel from a thin strip such as acontinuously cast thin strip the thin cast strip is processed to promoterecrystallization from the surface layer of the strip (S=0) into the quarterthickness of the strip (S=0.2 to 0.3). The process parameters are selected sothat the strain/recrystallization parameter (K*)-1, =about 6500 and wherein,Formula (I), THBA is the annealing temperature of the strip (in ~Kelvin), THRis the hot rolling temperature of the strip (in ~Kelvin), .epsilon. is thestrain rate of hot rolling, ti is the initial thickness of the strip beforehot rolling, and tf is the final thickness of the strip after hot rolling.
