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
The invention belongs to electrolytic aluminum anodic steel claw and manufacturing technology field thereof, be especially the anode steel claw of a kind of new structure.
Background technology
Electrolytic aluminum anodic steel claw structure manufacture require dense structure, without casting flaw, chemical composition is uniformly accurate, and it is cumbersome that traditional casting method makes anode steel claw processing step, it is easy to causes the secondary oxidation of molten steel, degree of purity can not be guaranteed, and the controllability of scaling loss elemental composition is poor.It is extremely difficult to electrolytic aluminum anodic steel claw resistivity low, the making requirement conducted electricity very well.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method that special electroslag metallurgy welding process method prepares Novel anode steel claw component, it is possible to increase the compactness of Novel anode steel claw melting welding, obtains high-quality, high performance anode steel claw product.
It is an object of the invention to be accomplished by:
A kind of novel energy-conserving anode steel claw, including transverse arm 1 and pawl head 2, is characterized in that;Transverse arm 1 and pawl head 2 are fixed together by electroslag molten welding 3；
The preparation method of above-mentioned a kind of novel energy-conserving anode steel claw is as follows:
(1) previously prepared cuboid pawl head and cylinder metal transverse arm parent blank, blank material is Q235, and these 2 kinds of metal carrier body stocks are placed in the water cooled mo(u)ld die cavity that anode steel claw structure is corresponding, is assembled location and couples；
(2) pouring in water cooled mo(u)ld die cavity by the flux melted, start power supply, described melting welding flux is by CeO2、CaF2、CaCO3、AL2O3, composition, wherein each composition by weight/mass percentage composition is: CeO25-18%、CaF243-58%、CaCO35-15%、AL2O318-25%；
(3) cosolvent is being exported from transformator with secondary low-voltage and electric current between cuboid pawl head and the cylinder metal transverse arm parent of fusion welding, the slag bath that cosolvent is formed is formed loop, the electric energy of loop input produces high resistance, highly active heat in slag bath, and cosolvent slag bath temperature is 1600--18500C, causes that parent that chemical composition material is identical and consumable consumable electrode form melting refinement and metallurgical binding welding；
(4) the active rare-earth Elements C e in cosolvent being carried out chemical reduction reaction, reducing agent is Si-Ca alloy, and wherein Si:Ca is 30:70 by mass percentage, makes rare earth element ce enter region, fusion welding metal alloying, purifies material.Liquid metal is comprehensive in melting welding volumetric region on the other hand gradually rises and solidifies, thus avoiding the generation of shrinkage cavity, pore casting flaw.
The present invention, compared with the anode steel claw work of existing conventional preparation techniques fabrication techniques, has the advantage that
1, avoid traditional handicraft or the existing welding procedure to there is " pollution " of metallurgical quality in metallic object, it is to avoid due in preparation technology series of temperature uneven affect welding quality, the deficiency of obdurability and bring anode steel claw potential safety hazard in Aluminum Electrolysis Production running.
In anode steel claw entirety electroslag molten welding process process, active rare-earth chemical reaction handling novel technique makes melting welding uniform temperature fields, fusion welding quality optimization, properties of product intensity and toughness high, and electric conductivity is superior.
Prepare with tradition compared with anode steel claw technique and existing welding procedure, hence it is evident that be in that the long-pending loop process method of electroslag molten welding rare earth slag cell body is simple, scientific and reasonable, effective.Fully phase out existing irrational metallurgical method conventional cast, human weld's technique.Electroslag molten welding new technology more meets the carrying out of melting welding product, has many, fast, good, province, scientific and reasonable.Because weldering territory, melting zone increases reaction interface, it it is the completely metallurgical fusion process of verity.
Apparatus and process is easy and simple to handle, applied widely, can the type of antianode steel pawl product flexible and changeable, just reach to meet the steel pawl diameter of different size and the technology requirement of height by changing melting welding frock.
The novel technique melting welding activity duration is short, and producing cost is lower than traditional handicraft, saves cost and avoids waste.The economic benefit that product is energy-saving and cost-reducing after using simultaneously is more notable.
