Date:2019-04-03 Author: Click:

At present, the repairing surfacing of working rolls and conveyor roll track in blooming mill and steel pipe mill mainly uses traditional surfacing device, that is, submerged arc welder with manual rotating rollers.The following problems will occur for this: 1. Manual rotating rollers are relatively laborious and uneven in rotation, which may easily result in inconsistent structure at the joints of straight-line welding seams in SAW welders, bite and sand holes; 2. Because rollers can only be welded in straight lines, one end of the rollers can not be welded by the welder (about 50mm), only manual welding can be used, causing inconsistency in roll welding materials, welding, etc.Joining quality can not be guaranteed completely; 3. The welding speed of SAW welder is not adjustable, the rollers rotate unevenly, which easily causes too large welding thickness, wastes welding materials, increases cutting difficulty, and leads to low welding efficiency.


summary of the invention


The utility model overcomes the defects of the original surfacing device that the welding quality cannot be fully guaranteed, the waste of welding materials and the low welding efficiency, and provides a roll repair automatic surfacing device.The roll repair automatic surfacing device uses automatic surfacing machine with roll rotation device to make the welding speed adjustable, the roll rotation speed is even, the quality of roll welding is guaranteed, and the efficiency of roll welding is improved.
