CaCO
3Be marmorean chief component composition, the marble that uses in the welding rod resolves into CaO and CO under the effect of arc heat
2Gas plays the effect of slag making and gas making, and CaO is basic anhydride, can improve slag basicity, and stable arc increases interfacial tension and the surface tension of slag and metal surface, improves deslag performance, and has and take off preferably S ability, CO
2Can reduce the hydrogen dividing potential drop in the arc atmosphere, reduce weld hydrogen content.But CaCO
3Too many meeting alligatoring molten drop is so be controlled at 28～40% with marble among the present invention.
CaF
2Being the Main Ingredients and Appearance of fluorite, is a kind of polygene mineral matter, belongs to alkaline fluoride, is that a kind of slag former, diluent also can play dehydrogenation effect, CaF in welding rod
2Under the welding arc effect, ionize out F
-, can reduce the dividing potential drop of hydrogen in the arc atmosphere, have and carbonate facics with effect.CaF
2Resolution reduce the content of oxygen in the deposited metal, be conducive to improve the low-temperature impact toughness of weld metal, CaF
2Fusing point is lower, can effectively reduce cinder high-temperature viscosity, improves slag fluidity, and improves electric conductivity, improves appearance of weld, and to improving welding procedure, improving the deposited metal mechanical performance has very large effect, reasonably CaF
2Content can play the effect of stable arc, if CaF
2Too high then arc stability variation, the slag hardening.In this invention, evidence CaF
2Better effects is arranged when 18-28%.
Rutile is purer titanium dioxide, TiO
2Be acidic oxide, can improve the physical property of slag, long slag is become short slag, make the slag variation with temperature fast, make appearance of weld good, improve the removability of slag, adding fashionable overall control 5～10%.
Cr makes on the one hand that to contain Cr amount in the steel higher, easily forms Cr
2O
3Oxide-film so that material has good anti-normal temperature, high temperature oxidation resistance, improves decay resistance; Can form M on the other hand
23C
6The type carbide, in matrix, play preferably carbide reinforced effect, play solution strengthening effect, increasing Cr content can make creep fracture time lengthen, but delta ferrite is easy to residual, suitably controls the content of Cr, makes Creq≤10(Creq=Cr+6Si+4Mo+1.5W+11V+5Nb+9Ti+12Al-40C-30N-4Ni-2Mn-1Cu), then δ-Fe can not occur, be conducive to obtain single martensitic structure.In order to be complementary with the T/P91 mother metal and to obtain good mechanical performance, among the present invention deposited metal Cr content is controlled at 8.50～10.50%.
The adding of Ni is conducive to improve the impact flexibility of weld seam, mainly is the Ac that Ni can reduce material
1Temperature improves tissue to the extent of reaction of tempering, reduces simultaneously the sensitiveness that delta ferrite forms.According to the data introduction: in Fe-Cr-Nb-Ni system, have a γ-α to change, because the matrix that contains the Ni alloy is to change the granular ferrite that forms by γ-α, raise until 600 ℃ the time in temperature, the intensity of alloy depends on the subgrain structure of ferrite matrix strongly, in the identical situation of Nb content, contain the Ni alloy ratio and do not contain Ni and present higher intensity.Yet having surpassed the mother metal set upper limit, nickel element and manganese element content can improve significantly its toughness, because they are to Ac
1The impact of temperature must consider to limit its content again.Among the present invention Ni is controlled at 1～1.8%.
Present two aspects of the acting body of N: play on the one hand solution strengthening effect, but the solubility of nitrogen in steel is very little under the normal temperature; On the other hand, in the heat treatment process, V (C, N) is appearred in priority separate out and play dispersion-strengtherning, greatly improved the creep rupture strength value, but can reduce its plasticity and toughness.Among the present invention nitrided ferro-chromium is controlled at 0.6～1.5%.
Mo is mainly solution strengthening, also participate in to form precipitation strength, can significantly improve creep limit and the stress-rupture strength limit of steel, and Mo can also make recrystallization temperature significantly raise, and so that the recovery temperature after distortion significantly improve; And the temperature range at 450 ℃-650 ℃ can suppress the gathering of cementite effectively, and promotes the alloy carbide of disperse to separate out, but adding Mo is too much, the brittle failure that can strengthen steel.Among the present invention deposited metal Mo content is controlled at 0.30～0.70%.
Nb is carbide, can form stable carbide NbC, this carbide is very stable, it can improve creep limit and the creep rupture strength of steel, particularly effect is more obvious when V and the compound adding of Nb, and to improve the heat resistance of steel be owing to form stable carbide NbC and Laves (NbFe to Nb in addition
2), dispersion-strengtherning is better.But along with the increase of Nb content can cause the reduction of percentage elongation, this is because NbFe
2Volume ratio increase and cause, too high Nb content significantly reduces the toughness of weld metal.Take into account creep rupture strength and impact flexibility.Among the present invention Nb-Fe is controlled at 0.4～0.8%.
Even the carbide that V forms in heat resisting steel under higher operating temperature, also relatively is difficult to assemble, this has just improved the heat resistance of steel, and the adding of V can obviously reduce creep speed.Compound adding V, Nb easily form the stable MX carbide of very thin disperse and produce precipitation strength (the most effective with the 0.25%V-0.05%Nb combination), very large on the creep rupture strength impact, and welding performance (fire check) and toughness are had adverse effect, so their content must be controlled in the low scope of standard permission.Among the present invention V-Fe is controlled at 1～1.8%.
Mn, Si add as deoxidier, and for avoiding again forming austenite under the highest post weld heat treatment temperature, Mn+Si should be controlled at 1.5% the scope that is limited in the weld metal.When Si and Cr exist simultaneously, can carry heavy alloyed high-temperature oxidation resistance, but the too high toughness that is unfavorable for weld metal of Si.Among the present invention Si-Fe is controlled at 2～5%, electrolytic manganese is controlled at 1.5～3%.
C a kind ofly can effectively control the delta ferrite forming element, adds C and can make the intensity of steel improve Plasticity Decreasing in steel.For guaranteeing welding processing, carbon content remains on a lower level.Among the present invention amorphous graphite is controlled at 0.2～0.6%.
In addition, for the removability of slag, deoxidation, appearance of weld and the good requirements such as mechanical performance of satisfying weld seam, the present invention has selected Si, Mn combined deoxidation, and the adding of manganese can improve intensity and toughness, it also is a kind of good desulfurizing agent, the adding of Ca also has good effect to dephosphorization, and each composition Proper Match in the welding rod has played good effect to the mechanical performance of weld structure and weld seam.
Beneficial effect of the present invention is: the supporting welding rod of the external corresponding ultra supercritical heat resisting steel of introducing adopts core wire different, exists in various degree arc stability poor during welding, and blow force of arc is little, spatter is large, the disadvantages such as welding bead is narrow, and appearance of weld is relatively poor, and deslag performance is bad.And be difficult to make welding technological properties and mechanical performance to reach simultaneously best.Welding rod of the present invention has solved above difficult point, not only has good processing performance, and has good 100,000 hours creep rupture strengths and high temperature creep property.
The present invention obtains full martensitic structure (containing hardly delta ferrite) to each composition Proper Match in the welding rod after being quenched in the weld(ing) deposit, through quenching-temper, microscopic structure is the tempered sorbite of Mo solution strengthening, and matrix contains the M that tempering is separated out
23C
6The V that metalloid carbide (Fe, the carbide of Cr or Mo) and MX form exist and carbon/nitride of Nb, M
2X and Laves mutually, each composition Proper Match has played good action to the mechanical performance of improving weld structure and weld seam in the welding rod, obtains the weld metal of good high temperature creep property and 100,000 hours creep rupture strengths.For the production of its Weld Performance of heat resisting steel be: welding point tensile strength 650～730Mpa, yield strength 550～630Mpa, percentage elongation 19～25%, 20 ℃ of Impact energy Ak v 〉=67J, and the rear weld porosity of welding, slag inclusion, crackle, diffusible hydrogen and outward appearance edge etc. all satisfy the requirement of ultra supercritical heat resisting steel properties of weld fully.
