Abstract The texture and microstructure gradient in hot rolled grain oriented silicon steel strip was one of the essential factors to achieve a perfect secondary recrystallization. The texture and microstructure of grain oriented silicon steel strip as-rolled with two different hot rolling parameters was investigated. The results show that with big reduction at the end rolling process, the intensity of {100}〈011〉 and {100}〈001〉 orientation reduces with ({111}-{113})〈110〉 orientation intensity enhanced in hot band, meanwhile the average grain size and the thickness of recrystallization zone are increased, after high temperature annealing, the second grain size and the Goss grains orientation deviation angle is smaller, and the magnetic permeability is better.
