Description
The present invention relates to a kind of used for submerged arc welding high-basicity sintered flux.
Find a United States Patent (USP) by retrieval, the patent No. is 3078193, and its solder flux chemical composition is: SiO
244.20%, CaO 1.06%, MgO 0.18%, Al
2O
32.00%, MnO 42.90%, TiO
20.08%, FeO 1.5%, Na
2O 0.34%, K
2O 0.36%, CaF
26.9%, BaO 0.11%, and this solder flux is acid fysed flux, can not be used for the welding of important structure.
For the processing performance of improving low-alloy high-strength steel submerged-arc welding and the mechanical performance of weld seam, developed this high-basicity sintered flux.
This solder flux adopts that domestic amount is easy to get greatly, 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.
With the United States Patent (USP) ratio that retrieves following difference is arranged:
The first, what United States Patent (USP) was reported is a kind of smelting type welding flux.Because the production of fysed flux is use electric arc furnace smelting, solder flux power consumption per ton is the 1500-2000 degree, and a large amount of pernicious gas of generation when smelting.The production technology of sintered flux then is to add the waterglass granulation by powder--oven dry--sintering in the high temperature furnace, power consumptive province not only, and also pollution-free, be convenient to automated production.
The second, the solder flux of U.S. Patent Publication, the SiO in its main component
2With the content of MnO up to 87%, the basicity computing formula of recommending by International Institute of Welding:
Basicity=(CaO+MgO+BaO+CaF
2+ R
2O+1/2 (MnO+FeO))/(SiO
2+ 1/2 (Al
2O
3+ TiO
2))
Calculate, basicity is about 0.7, and it is to belong to acid flux, and solder flux of the present invention, basicity＞3 belong to high basicity solder flux, CaF in its composition
2With the total amount of basic anhydride MgO, CaO up to 60%.Because SiO in the acid flux
2Content height, oxidisability are too strong, and the alloying element scaling loss is serious during welding, and weld seam oxygen content height causes the weld seam cold impact value low.
The 3rd, solder flux of the present invention does not contain the BaO composition, and to have added rare earth oxide composition and percentage composition content that both are identical also inequality more.By improving CaF
2Content, increase the dehydrogenation ability, thereby reduced the diffusible hydrogen content of weld seam.By adding the abundant rare earth oxide of china natural resources, improved the form of field trash in the weld seam, further improved the low-temperature impact toughness of weld seam, make solder flux of the present invention have ultralow hydrogen, high tenacity, the good characteristics of welding technological properties.
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, in flat board or the groove during welding or postwelding all can take off slag automatically, be particularly suitable for narrow gap, the welding of narrow groove.60
0Still can take off slag automatically when welding in the double V-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 A5.23-80-welding, and σ s 〉=550MPa, σ b 〉=650MPa δ 5 〉=22.0%, ψ 〉=65.0%, ballistic work (60 ℃) 〉=34J.When 2 1/4 CrlMoA steel plates cooperated homemade H08Cr2.25-Mo1A welding wire to weld, every index all satisfied the regulation requirement.
Most preferred embodiment: aluminium oxide 21%, fluorite 24%, magnesia 26%, big physics and chemistry 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
