Working roller storage device for finishing mill

Abstract

The invention discloses a working roller storage device for a finishing mill. The working roller storage device comprises a plurality of storage units, wherein each storage unit comprises four stand columns, two longitudinal beams, two cross beams and two supporting frames matched with end shafts of working rollers, the four corresponding stand columns are located in the left front direction, the left rear direction, the right front direction and the right rear direction of the stored working roller respectively, the lower ends of the two stand columns on the left side of each working roller are connected through one longitudinal beam, the lower ends of the two stand columns on the right side of each working roller are connected through another longitudinal beam, the lower ends of the two stand columns in front of each working roller are connected through one cross beam, the lower ends of the two stand columns in the rear of each working roller are connected through another cross beam, the two corresponding supporting frames are fixed to the middles of the two corresponding cross beams, and butt joint positioning mechanisms are arranged at the two ends of each stand column. According to the working roller storage device, the plurality of storage units stacked together are used for storing the working rollers, the lower-layer working rollers do not bear the pressure of the upper-layer working rollers, and mutual friction and extrusion do not exist between the working rollers so that the number of stacking layers can be increased, the occupied area can be reduced, the falling risk does not exist, and the safety of the working rollers can be guaranteed.

Description

technical field [0001] The invention relates to a device for accommodating and storing work rolls of a finishing mill, which can save storage space and prevent the surface of the work rolls from being damaged due to mutual friction and extrusion, and belongs to the technical field of storage. Background technique [0002] Rolling mills need to store a large number of work rolls of hot-rolled coil finishing mills. The common storage method is to stack the work rolls on the ground. In order to prevent the bottom layer of work rolls from being damaged due to excessive pressure, the number of stacked layers should not be too large Many, so this storage method occupies a large area. In addition, the existing storage method not only has the risk of falling, but also the friction and extrusion between the work rolls will cause the surface damage, which will affect the surface quality of the rolled slab and reduce the qualified rate of the product. Another disadvantage of the exist...

Problems solved by technology

[0002] Rolling mills need to store a large number of work rolls of hot-rolled coil finishing mills. The common storage method is to stack the work rolls on the ground. In order to prevent the bottom layer of work rolls from being damaged due to excessive pressure, the number of stacked layers should not be too large Many, so this storage method occupies a large area

In addition, the existing storage method not only has the risk of falling, but also causes damage to the surface of the work rolls due to mutual friction and extrusion, which in turn affects the surface quality of the rolled slab and reduces the qualified rate of the product

Another disadvantage of the existing storage method is that the space between the work rolls is small, the specific location is inconvenient to count, and the assembly of the bearing seats on both sides is also relatively difficult, which must be hoisted to the designated platform by the crane before assembly
