Abstract: Structure  and  texture  orientation  of  50W600  cold  rolled  non-orientation  electrical  steel(0.003～0.008C,0.3Si)during  annealing  at  700～760  ℃  for  3～360  s,water  cooling  have  been  studied  by  metallography  and  electron  back-scattering  spectrum  difraction  analysis.Results  showed  that  incrensing  annealing  temperature  the  rate  of recrystaliza-tion and grain size increased; during annealing at 740 ℃,as annealing time increased from  10 s to 360 s,the rate of recrys-tallization increased from 22.5% to  100% and average grain size increased from 3.08  μm to  17.17 μm,and the density of  recrystallization texture at α- fibre decreased,as annealing for  15 s the density of {001}〈110〉,{112}〈110〉,{111}〈110〉 and ｛110｝〈110〉was abot 1.5 and the density of ｛111｝〈011〉 and ｛111｝〈112〉at γ-fibre was steadily about 0.25.
