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 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 . 0.15 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 (&egr;)} 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.
