This apparatus is composed of a vertical rolling mill with the rolls 31 and two pairs of horizontal drive-free rolls 33 and 34 disposed on the entry and delivery sides of the vertical rolling mill respectively. These drive-free rolls 33 and 34 can put some rolling load on the billet 10 owing to the propulsive force of the vertical rolling mill, though the drive-free rolls are defined as rolls which are not electrically driven.

2015-8-28 The rolling mill is one of the nonlinear systems which include many fields, such as network control [1, 2], feedback control [3, 4] and so on. Considering the dynamic changes of vibration displacement of cold rolling mill roller in vertical direction, Hou et al. established a dynamic rolling force model. They found that with the change of the external disturbance force, the rolling mill would make

Rolling mill stands are historically made as a steel casting but today many are fabricated from cast slabs or rolled plate. The cross section of the post is measured in square inches (mm 2) which determines the housings separating force. Rolling mill stands can be designed as 2 high, 3 high, 4 high, 6 high or 20 high roll configurations.

Friction-induced vibration is a typical self-excited phenomenon in the rolling process. Since its important industrial relevance, a rolling mill vertical-torsional-horizontal coupled vibration model with the consideration of the nonlinear friction has been established by coupling the dynamic rolling process model and the rolling mill structural model. Based on this model, the system stability ...
