Problems solved by technology

In this repair method, there is a cavity in the center between the steel claw leg and the steel rod that is not welded but is surrounded and sealed by the weld. The huge tension of the disengagement trend may cause the artificially repaired steel claw legs to "break" at the weld seam, and the energy consumption is also high

Abstract

The invention relates to a fusing agent, particularly a fusing agent used at the fusion welding stage in the process of the electrolytic aluminium anodic steel claws repairing. which aims at providing a fusing agent capable of producing no air holes on the welding portion, increasing melting speed and reducing energy consumption. The following technical scheme is adopted: the fusing agent applied to electrolytic aluminium anodic steel claws repairing is composed of A12O3, CaF2and CaO. Compared with the prior technology, the fusing agent for electrolytic aluminium anodic steel claws repairing has the advantages in that: (1), the fusing agent floats in a metal pool and isolates outside air so as to avoid producing defects such as shrinkages, air holes and the like (2), the fusing point is decreased, fusing speed is increased and the energy consumption is reduced.

Description

technical field [0001] The invention relates to a flux, in particular to a flux used in the fusion welding stage in the repair process of electrolytic aluminum anode steel claws. Background technique [0002] At present, the domestic electrolytic aluminum production enterprises all use manual electric welding to repair the steel claws, remove the severely corroded parts of the steel claw legs, and weld them with new steel rods by electric welding. In this repair method, there is a cavity in the center between the steel claw leg and the steel rod that is not welded but is surrounded and sealed by the weld. The huge tension of the disengagement trend may cause the artificially repaired steel claw legs to "break" at the weld seam, and the energy consumption is also high. Contents of the invention [0003] The purpose of the present invention is to provide a flux that can ensure that the welding part does not produce pores, increase the melting speed and reduce energy consump...
