Problems solved by technology

[0003] The present invention solves the problem that when the aluminum plate is processed by the existing hot rough rolling mill, a slight depression occurs in the center of the aluminum plate due to the influence of gravity, which causes interference with the bearing seat of the rotating roller table, scratches the lower surface of the aluminum plate, and damages the bearing seat or gland screw. problem, and then propose a device and method for preventing scratches on the lower surface of the aluminum plate of the hot roughing mill

Abstract

The invention discloses a device and method for preventing the lower surface of an aluminum plate of a hot roughing mill from being scratched, and relates to the technical field of hot roughing machining. The problems that when an existing hot roughing mill is used for machining an aluminum plate, the middle of the aluminum plate is slightly sunken due to the gravity effect, the aluminum plate interferes with a bearing seat of a rotating roller way, the lower surface of the aluminum plate is scratched, and the bearing seat or a gland screw is cracked up are solved. The device comprises an anti-collision beam and a plurality of driven roller mechanisms, wherein a plurality of limiting grooves are evenly distributed in the upper end face of the anti-collision beam in the length direction, each driven roller mechanism is inserted into one limiting groove, and the axis direction of the driven roller mechanisms is arranged in the width direction of the anti-collision beam. The method comprises the steps of installing the driven roller mechanism; determining the position of an anti-collision beam; and mounting the anti-collision beam. The method is used for processing the aluminum plate by the hot roughing mill.

Description

technical field [0001] The invention relates to the technical field of hot rough rolling, in particular to a device and method for preventing scratches on the lower surface of an aluminum plate in a hot rough rolling mill. Background technique [0002] With the development of science and technology, the times continue to progress. More and more attention has been paid to the surface quality of aluminum sheets passing through hot roughing mills. In the current 3950mm hot roughing mill, there are five sets of rotating roller tables at the entrance of the rolling mill, which are used for the rotation of the ingot for the first few passes of horizontal widening rolling. The bearing housings of the roller tables are located on the center line of the rolling mill. When producing thin plates below 20mm, since the hot aluminum plate at around 400°C is relatively soft, a slight depression occurs in the middle of the aluminum plate under the influence of gravity, which interferes wit...
