Preparation method for novel energy-saving anode steel claw

Abstract

The invention discloses a novel energy-saving anode steel claw. The novel energy-saving anode steel claw comprises a cross arm and claw heads, and is characterized in that the cross arm and the claw heads are bonded and fixed together through electroslag fusion-welding. A preparation method comprises the following steps: arranging pre-prepared claw head and cross arm matrix blanks Q235 in a water-cooling model cavity corresponding to an anode steel claw structure, and assembling, locating and connecting the blanks; pouring a flux which is already melted into the water-cooling model cavity, starting a power supply, and carrying out the processes of melting refining and metallurgical bonding welding between the cuboid claw head matrixes and the cylindrical metal cross arm matrix which are subjected to fusion-welding through the flux. Rare-earth active element Ce in the flux is subjected to a chemical reduction reaction, and enters a metal fusion-welding area to be alloyed, thus the material is purified. On the other hand, liquid metals are omni-directionally gradually ascended and solidified in a volume fusion-welding area, thus the generation of casting defects of shrinkage cavities and air holes is avoided. According to the preparation method disclosed by the invention, the overall electroslag fusion-welding is adopted, a fusion-welding temperature field is uniform, the fusion-welding quality is optimized, the performance, strength and toughness of the product are high, and the conductive performance is excellent.

Description

Technical field [0001] The invention belongs to the technical field of electrolytic aluminum anode steel claw and its manufacturing technology, and is specifically an anode steel claw with a novel structure. Background technique [0002] The production of electrolytic aluminum anode steel claw components requires dense structure, no casting defects, uniform and accurate chemical composition. The traditional casting method produces anode steel claws with complicated process steps, which can easily cause secondary oxidation of molten steel, and the purity cannot be guaranteed, and burning The controllability of the loss element composition is poor. It is difficult to meet the production requirements of electrolytic aluminum anode steel claws with low resistivity and good electrical conductivity. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a special electroslag metallurgical fusion welding process method to prepare a...
