Technical field
The invention belongs to the flux of anode steel claw electroslag molten welding process.
Background technology
The overall spare part of anode steel claw makes and requires that matrix is fine and close, without casting flaw, and metallurgical high purity.Current technology technology adopts manual electric arc welding to connect global formation anode steel claw, and institute's welded structure area is little, does not reach gross area welding.Therefore spare part poor electric conductivity in production run use procedure, it is short to increase power consumption, life-span.
Summary of the invention:
The technical problem to be solved in the present invention is to provide a kind of rare earth slag combination flux manufactured for overall anode steel claw melting welding, can purify material, improve degree of purity, guarantee that melting welding region portion does not produce casting flaw.
Be in order to achieve the above object, technical scheme of the present invention realizes by with under type:
A rare earth slag flux for anode steel claw melting welding, is characterized in that: described rare earth slag flux is by CeO 2, CaF 2, CaCO 3, AL 2o 3, composition, wherein each composition by mass percentage is: CeO 2: 5-18%, CaF 2: 43-58%, CaCO 3: 5-15%, AL 2o 3: 18-23%.
A rare earth slag flux for anode steel claw melting welding, is characterized in that: described rare earth slag flux is by CeO 2, CaF 2, CaCO 3, AL 2o 3, composition, wherein each composition by mass percentage is: CeO 2: 7-16%, CaF 2: 43-58%, CaCO 35-12%, AL 2o 3: 18-23%.
Described rare earth slag combination flux is applied in the auxiliary material used in melting welding anode steel claw process, and flux, by being broken into 1 ~ 5mm granular mixture, uses after drying.
Adopt rare earth slag of the present invention to combine flux compared with prior art, have the following advantages: fusion process rare earth slag flux resistance value is high, fusing point is low, good fluidity, forms slag bath soon.Be separated by with air and effectively avoid the air secondary oxidation stain of melting welding body, improve metal molten speed simultaneously, energy-saving and cost-reducing.Rare earth slag flux chemical reactivity is strong, in the effective absorb inclusion harmful substance of fusion welded zone slag bath, makes it to build up and floats.Rare earth element ce plays purification, rotten melting welding matrix, makes matrix grain refinement, even, compactness raising; Finally cause the electric conductivity obviously improving anode steel claw.
