Abstract：

The transverse rigidity of load-carrying roll gap represents the ability of the load-carrying roll gap convexity remaining constant while resisting fluctuation of rolling force. To analyze the strip shape control characteristics of the entire roll gap, the concept of transverse rigidity along entire roll gap was proposed. For four-roller strip mill, the finite element analysis model coupling the bearing boxes of back-up roll, bearings, rolls and rolled piece was established by the 3-D elastic-plastic finite element model, and influences of strip width, reduction rate, rolling resistance and tension on the transverse rigidity of each point in the roll gap of the four-roller strip mill were analyzed. The results show that the transverse rigidity of each point in the roll gap increase with the increase of strip width and tension, and decreases with the increase of reduction rate and rolling resistance.
