Flux recycling device for overlaying welding on roller

Abstract

The invention discloses a flux recycling device for overlaying welding on a roller. The flux recycling device comprises a roller driving device and a flux conveying device, wherein the roller drivingdevice comprises two supports, the roller can be installed between the two supports, the flux conveying device is arranged on the side faces of the supports and comprises a tower, and a flux bucket loaded with a flux is arranged at the top of the tower; supporting plates are installed on the two side faces of the supports respectively, at least two spring supporting devices are installed on each supporting plate, and a vibratory screening mechanism which is fixedly connected with the tops of the spring supporting devices is installed at the portion, below the roller, between the two supports,and comprises a framework; a screening net is installed in the middle of the framework, a vibration motor is installed at the periphery of the framework, a flux recycling box is arranged below the vibratory screening mechanism, a discharging port is formed in the bottom of the flux recycling box, a conveying pipeline is installed between the discharging port and the flux bucket, and an induced draft fan is installed on the conveying pipeline. By means of the flux recycling device, the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of roll overlay welding repair, in particular to a flux recovery and reuse device for roll overlay welding. Background technique [0002] Steel plate production usually adopts roll rolling, and the roll rolls cylindrical billets or rectangular billets into thin steel plates. As the rolls are used for a long time, the surface of the rolls will be greatly worn. In the end, the production quality cannot be guaranteed, and the cost of replacing the rolls is too high. , in order to save costs, the worn rolls are usually removed for surfacing repair; [0003] A large amount of flux is required in the surfacing process, and most of the excess flux falls off the surface of the roll. Usually, a box is placed under the roll to recover the excess flux and slag generated by surfacing, and then the flux is sieved out again through a sieve. However, at present, the box is taken out for screening after the machine is shut...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the existing roll surfacing repair process, the box is taken out for screening after shutdown, and then transported to the flux barrel separately after screening, which obviously affects the production efficiency. The flux recovery and reuse device for roll surfacing can recycle and reuse excess flux without shutting down
