摘要（英）：

The invention discloses a roll gap of a multi-roll straightener, and belongs to the technical field of steel plate straightening. The roll gap equation of a third straightening roll is: k = 1+p-p2/2; R=E.t.(1-p)/sigmas, wherein E represents the elasticity modulus of the strip steel, t represents the thickness of the strip steel; and sigmas represents the yield strength of the strip steel, and p represents the proportion of the plastically deforming area in the cross section of the strip steel in a thickness direction. The roll gap is applicable to development of on-line control models. The models developed by using the roll gap are simple and practical; and when the roll gap is used, the residual stress in the strip steel can be eliminated effectively, the quality of the strip profile of the strip steel can be improved, the bearing capacity of the equipment can be lowered, and economic benefits can be increased.
