Abstract: The relationship between strip shape and strip deviation was obtained by analyzing the force of rolled hard strip steel running on the roll surface of the annealing line and combining with the actual silicon steel sheet shape cold rolled on the six-high reversible rolling mill of Masteel. And then according to the actual situation of silicon steel production line in a steel mill and the correlation analysis between the sheet shape and the deviation, effective measures to reduce the deviation of the annealing line were formulated. These measures were playing a key role in deviation control combined with the roll system reform of the annealing line and the improvement of the deviation correction ability.

Key words: silicon steel, annealing line, sheet shape, deviation
