Abstract:
In a method of producing a strip suitable for further processing to yield a (110)null001null 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 (Snull0) into the quarter thickness of the strip (Snull0.2 to 0.3). The process parameters are selected so that the strain/recrystallization parameter(K*)null1, nullabout 6500 and wherein, 1 ( K * ) - 1 = ( T HBA ) null ln null [ e . 015 null exp null ( 7616 T HR ) null ln null ( t c t f ) ] THBA is the annealing temperature of the strip (in null Kelvin), THR is the hot rolling temperature of the strip (in null Kelvin), {dot over (null)} 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.
