Method of producing (110)[001] grain oriented electrical steel using strip casting

Abstract

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 a continuously cast thin strip the thin cast strip is processed to promote recrystallization from the surface layer of the strip (S=0) into the quarter thickness of the strip (S=0.2 to 0.3). The process parameters are selected so that the strain/recrystallization parameter(K*)−1, ≧about 6500 and wherein, 1 ( K * ) - 1 = ( T HBA ) ⁢ ln ⁡ [ e . 015 ⁢ exp ⁡ ( 7616 T HR ) ⁢ ln ⁡ ( t c t f ) ] THBA is the annealing temperature of the strip (in ° Kelvin), THR is the hot rolling temperature of the strip (in ° Kelvin), {dot over (ε)} is the strain rate of hot rolling, ti is the initial thickness of the strip before hot rolling, and tf is the final thickness of the strip after hot rolling.
