The deviation of operating slide clearance will lead to the instability of rolling, will influence the quality ofshapeofstrip, and will cause the damage to the equipments.
滑板间隙偏差将导致轧制不稳定，影响板形质量，并使设备受损。

When leveled by bend the strip is applied by a tension, under the influence of the tension and repeated leveling by bending strip is permanently elongation deformed, improving shapeofstrip.
The emulation experiment indicated that the controlling effect was well, namely little transfinite regulation and good robustness, the shapeofstrip could be controlled on-line and intelligently.
