Intelligent roller preheating device and preheating method thereof

Abstract

The invention discloses an intelligent roller preheating device. The intelligent roller preheating device comprises a box body and a box cover hinged to one side of an opening in the top end of the box body, wherein a bottom groove is formed in the center of the bottom wall of an inner cavity of the box body, supporting plates are fixed to the two sides of the bottom groove, semicircular through grooves are symmetrically formed in the top ends of the two supporting plates, and semicircular bearings are installed in the through grooves; sliding plates and supports are fixed to the opposite sidefaces of the two sets of supporting plates correspondingly, a lifting supporting mechanism is installed between the two sets of supporting plates, telescopic rods are fixed to the positions, horizontally corresponding to the through grooves, of the top ends of the side faces, facing the supporting plates, of the sliding plates correspondingly, and the sliding plates are connected with clamping plates for clamping a roller through the telescopic rods; and reciprocating mechanisms for driving the sliding plates to reciprocate are further arranged at the two ends of the sliding plates. Accordingto the intelligent roller preheating device and the preheating method thereof, intelligent treatment of the roller is achieved, manual operation steps are reduced, the preheating efficiency is improved, and the roller is convenient to take out and place.

Description

technical field [0001] The invention belongs to the technical field of rolling mill equipment, and in particular relates to an intelligent roll preheating device and a preheating method thereof. Background technique [0002] During the cold rolling process of metal materials, due to the thin thickness and large deformation of the rolled strip, and the temperature of the rolled strip can reach 120-150°C, the temperature of the roll has a great influence on the stability and stability of the rolling process. Quality control is very critical. In the production process of general cold tandem mills, it is inevitable to change rolls. Since the new rolls are directly loaded into the frame at normal temperature, there is an obvious temperature difference (about 50-60°C) between the new rolls and the old rolls. When the temperature of the working rolls is too low, direct rolling is likely to cause roll explosion. Therefore It is necessary to preheat the rolls when the rolls are rep...

AI Technical Summary

Problems solved by technology

[0003] At present, the common operation of the device for preheating the rolls is to preheat the rolls with steam manually, resulting in low efficiency during the preheating process, and most of them can only process one set of rolls at a time. As a result, the overall work efficiency is low. In addition, the corresponding processing equipment can only preheat rolls of a specific size, and the scope of adaptation is narrow.
