  • Patent number: 6749693
    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, ( K * ) - 1 = ( T HBA ) ⁢ ln ⁡ [ e . 0.
