Abstract
The invention discloses a device for adjusting a rolling line level of a medium plate mill, which comprises a lower support roll, bearing blocks which are arranged at the two ends of the lower support roll, a frame which is provided with a lifting hydraulic cylinder, a fixed guide frame, a movable guide frame and a horizontal push-pull mechanism. A roll-exchange vacancy is reserved in the adjusting device of the invention and an integrated step pad is divided into a plurality of blocks; during the exchange of the roll, the support roll is moved to the roll-exchange vacancy so as to avoid frequency exchange of the step pad, which means the step pad is not required to be moved outside along with the support roll when the support roll is exchanged; and thus, the roll exchange efficiency is improved and the vertical adjustment of the rolling line level can be realized quickly at each pass. The device has the advantages of simple and compact structure, wide adjustment range and high working efficiency and is capable of compensating for the rolling line height after the roll is worn.
Description
Technical field
