Description
Technical field
The invention belongs to electrolytic aluminum anodic steel claw and its manufacturing technology fields, are especially a kind of new structural anode steel
Pawl.
Background technology
The making of electrolytic aluminum anodic steel claw component requires dense structure, without casting flaw, and chemical composition is uniformly accurate, traditional
Casting method making anode steel claw processing step is cumbersome, easily causes the secondary oxidation of molten steel, and degree of purity cannot be guaranteed, and
The controllability of scaling loss elemental composition is poor.It is extremely difficult to the making requirement that electrolytic aluminum anodic steel claw resistivity is low, conducts electricity very well.
Invention content
The technical problem to be solved by the present invention is to provide a kind of special electroslag metallurgy welding process method and prepare Novel anode
The method of steel claw component can improve the compactness of novel anode steel claw melting welding, obtain high quality, the production of high performance anode steel claw
Product.
The purpose of the present invention is what is be accomplished by the following way：
A kind of novel energy-conserving anode steel claw, including transverse arm 1 and pawl head 2, it is characterized in that;Transverse arm 1 and pawl head 2 are molten by electroslag
Weldering 3 is fixed together；
A kind of preparation method of above-mentioned novel energy-conserving anode steel claw is as follows：
（1）Previously prepared cuboid pawl head and cylinder metal transverse arm parent blank, blank material Q235, this 2 kinds
Metal carrier body stock is placed in the corresponding water cooling model cavity of anode steel claw structure, is assembled positioning connection；
（2）The fluxing agent melted is poured into water cooling model cavity, startup power supply, the melting welding fluxing agent is by CeO2、
CaF2、CaCO3、AL2O3, composition, wherein each ingredient is by mass percentage：CeO2 5-18%、CaF2 43-58%、CaCO3 5-
15%、AL2O3 18-25%；
（3）Cosolvent is being exported two between the cuboid pawl head of fusion welding and cylinder metal transverse arm parent by transformer
Secondary low-voltage and electric current cooperation, are formed into a loop in the slag bath that cosolvent is formed, and the electric energy of circuit input generates height in slag bath
The heat of resistance, high activity, cosolvent slag bath temperature are 1600--18500C leads to the identical parent of chemical composition material and oneself
It consumes consumable electrode and forms melting refinement and metallurgical binding welding；
（4）Chemical reduction reaction is carried out to the active rare-earth Elements C e in cosolvent, reducing agent is Si-Ca alloys, wherein
Si：Ca is 30 by mass percentage：70, so that rare earth element ce is entered fusion welding metal region alloying, purifies material.On the other hand
Liquid metal is comprehensive in melting welding volumetric region to be gradually risen and solidifies, to avoid shrinkage cavity, the generation of stomata casting flaw.
The present invention has the following advantages compared with the anode steel claw work that existing conventional preparation techniques technology makes：
1, traditional handicraft or existing welding procedure are avoided there are " pollution " of metallurgical quality in metallic object, is avoided due to system
Uneven the influences welding quality of series of temperature in standby technique, the deficiency of obdurability and bring anode steel claw in Aluminum Electrolysis Production fortune
Security risk during row.
During anode steel claw entirety electroslag molten welding 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 are high, and electric conductivity is superior.
Compared with tradition prepares anode steel claw technique and existing welding procedure, hence it is evident that be that electroslag molten welding rare earth slag pond body is accumulated
Loop process method is simple, scientific and reasonable, effective.Fully phase out existing unreasonable metallurgical method conventional cast, human weld
Technique.Electroslag molten welding new process more meets the progress of melting welding product, has more, fast, good, province, scientific and reasonable.Because welding melting zone domain
Reaction interface is increased, is the complete metallurgical fusion process of authenticity.
Apparatus and process is easy to operate, applied widely, can be flexible and changeable to the type of anode steel claw product, molten by changing
Mounted welder just reaches the technology requirement of the steel pawl diameter and height that meet different size.
The novel technique melting welding activity duration is short, and producing cost is lower than traditional handicraft, cost-effective to avoid wasting.It produces simultaneously
Product are more notable using rear energy-saving economic benefit.
