Roller hot welding strip submerged arc automatic surfacing device

Abstract

The invention discloses a roller hot welding strip submerged arc automatic surfacing device. The roller hot welding strip submerged arc automatic surfacing device comprises a roller rotation driving device used for driving a roller which is about to be subjected to surfacing to rotate, and a welding assembly used for surfacing of the roller which is about to be subjected to surfacing on the rollerrotation driving device. The welding assembly is arranged on a guide rail in a sliding manner, wherein the guide rail extends in the axial direction of the roller which is about to be subjected to surfacing. One end of the guide rail is provided with a sliding driving device capable of driving the welding assembly to slide along the guide rail. The welding assembly comprises a sliding base capable of sliding along the guide rail. The sliding base is provided with a welding mechanism capable of heating and welding a welding strip. The positions, located on the two sides of the welding mechanism, on the sliding base are each provided with a welding flux conveying pipeline for guiding welding flux into a molten pool. According to the roller hot welding strip submerged arc automatic surfacingdevice, welding strip heating through a special welding strip heating device is not needed, the integral structure is simple, automatic roller surfacing can be achieved, the surfacing quality is improved, and the surfacing efficiency is improved as well.

Description

technical field [0001] The invention relates to the technical field of roll surfacing welding, in particular to an automatic submerged arc surfacing device for roll thermal welding strips. Background technique [0002] The surfacing roll refers to manufacturing or repairing the roll with various surfacing methods on the roll core with good toughness. It is one of the production methods of the composite roll. A powerful measure to improve the operating rate of the rolling mill and the quality of rolled products. [0003] In order to improve the efficiency of surfacing welding, hot wire is generally used for surfacing welding of rolls. At present, the device used for surfacing welding of rolls needs to use a special welding wire heating device to heat the welding wire, and then guide the welding wire heated by the welding wire heating device to the Welding in the molten pool, using this kind of hot wire surfacing device, the structure is relatively complicated; in addition, t...
