Description
The present invention relates to a kind of used for submerged arc welding high-basicity sintered flux.
At present, in the domestic solder flux kind, no matter be smelting type or sintered flux, all do not have a kind ofly can be applicable to σ
bThe universal solder flux of welding of 〉=490～784MPa Hi-Stren steel and the welding of 2 1/4 Cr1Mo steel.External " universal " sintered flux must cooperate their welding wire welding just can reach good welding performance, and cooperate homemade welding wire welding, and then welding seam toughness is on the low side, welding procedure variation, removability of slag variation when particularly narrow gap welding connects.It is in addition, external that " universal solder flux price all, costs an arm and a leg more than 10,000 yuans per ton.
For the processing performance of improving low-alloy high-strength steel submerged-arc welding and the mechanical performance of weld seam, save foreign exchange and also reduce cost, developed this high-basicity sintered flux.
This solder flux adopts domestic amount to be easy to get greatly, and cheap ore powder is a primary raw material.It is characterized in that chemical composition (with reference to the GB5292-85 analytical method) contains 7.0～17.0%SiO by weight
2, 15.0～25.0%Al
2O
3, 5.0～17.0%CaO, 15.0～40.0%MgO, 10.0～35.0%CaF2,0.5～5.0%TiO
2, FeO+MnO＜6%, K
2O+Na
2O＜6%, RexOy＜3%, this flux basicity are 3.0～3.7.
When adopting high basicity solder flux of the present invention to weld (cooperating homemade submerged-arc welding wire commonly used), arc voltage is stable, and weld fumes is minimum, and figuration of bead is good, and postwelding all can take off slag automatically when welding in flat board or the groove, is particularly suitable for narrow gap, the welding of narrow groove.Still can take off slag automatically when welding in 60V type groove, toe of weld does not have dry slag.Flux particle intensity height, moisture resistance is good, weld metal diffusible hydrogen＜1.0 milliliter/100 grams (glycerine method).This solder flux cooperates homemade H08Mn2MoA welding wire, during by Unite States Standard ANSI/AWS A5.2380-welding, and σ s 〉=550MPa, σ
b〉=650MPa δ 5 〉=22.0%, ψ 〉=65.0%, ballistic work (60 ℃) 〉=34J.When cooperating homemade HO8Cr2.25-Mo1A welding wire to weld on 2 1/4 CrlMoA steel plates, every index all satisfies the regulation requirement.
The solder flux of the same type of this solder flux import substitution, the RMB of saving per ton is more than 1/2～3/4.
Most preferred embodiment: aluminium oxide 21%, fluorite 24%, magnesia 26%, marble 15%, silica flour 5.5%, feldspar 2.5%, manganese ore 2.5%, titanium dioxide 2%, rare earth III 1.5%.
As bonding agent, addition accounts for 20% with the commercial water glass, flux basicity Bi=3.3.
