Abstract: The test of grooved roll pass rolling process to simulate steel works mill with roll diameter 1 200 mm, length of roll body 2 200 mm, maximum rolling force 25 000 kN and mill power 1 000 kW by laboratory mill with roll diameter 130 mm, length of roll body 265 mm, maximum rolling force 150 kN and mill power 5. 5 kW is carried out by using geometric similarity 1： 10 roller and lead stock to study the effect of reduction 0. 1 ~ 0. 5 mm, roll diameter 97.72 ~ 107. 65 mm and rolling lubrication coefficient 0. 21 ~ 0.45 on variation of rolling stock width. Results show that with increasing width of rolling stock and fabrication coefficient the spread of shape steel increases ； it is available to study on spread of shape steel with complex section by combined effect model of divided complex non-symmetry face studied results ； the obtained cutting pass spread calculated model is qualified by laboratory rolling deformation measuring.
