Qu Wenti.(2) stainless steel band pole sintering-flux for build-up welding (publication number: 102581518A).The solder flux that this patent proposes comprises electricity
Slag and submerged arc two kinds, be primarily upon joining EQ309L, EQ308L and EQ347L welding, be not directed to join EQ309LMo and EQ316L welding
Welding, be also not directed to post weld heat treatment and lateral thrust problem (side bend test of especially t=3mm).Above-mentioned patent is equal
It is not directed to join the welding of EQ309LMo and EQ316L, and post weld heat treatment and lateral thrust problem.
Summary of the invention
It is an object of the invention to provide a kind of stainless steel band pole submerged arc overlay welding solder flux carrying out post weld heat treatment, specially join
EQ309LMo and EQ316L welding uses, and can carry out post weld heat treatment, and bending (lateral thrust of especially t=3mm) and intergranular
Corrosive nature is excellent, it is possible to be applied to the welding of the high temperature container inner wall built-up welding such as hydrogenation reactor, coal gasifier.
The technical scheme that the present invention is used by realizing above-mentioned technical purpose is: a kind of carry out the stainless of post weld heat treatment
Steel band pole submerged arc overlay welding solder flux, according to percentage by weight, this solder flux is by the magnesia of 31-33%, the fluorite of 3-6%, the oxygen of 12-15%
Change aluminum, the crome metal of 2-3%, the metal molybdenum of 3-4%, the quartz of 10-14%, the cryolite of 3-5%, the calcium aluminate of 2-4%, 1-3%
Carboxymethyl cellulose and the pure sodium silicate of 21-24% mix.
In described magnesia, the content of magnesium oxide is not less than 93%, and the content of silicon oxide is less than 3.5%.
In described fluorite, the content of calcium fluoride is not less than 95%, and the content of silicon oxide is less than 1%.
In described quartz, the content of silicon oxide is not less than 97%.
In described pure sodium silicate, the content of sodium oxide is not less than 8.2%, and the content of silicon oxide is not less than 27%.
Patent of the present invention uses MgO-CaO-CaF2-Al2O3-SiO2Basic slag system, solder flux with basic anhydride, fluoride,
Neutral oxide, acidic oxide, binding agent and alloy are main, add a small amount of fluoaluminate, aluminate simultaneously and improve pressure
The material of painting property, the granularity of each raw material and composition are as shown in Figure 1.
In this solder flux, the Main Function of each composition is summarized as follows:
Magnesia: Main Function is slag former, fusing point, viscosity and the interfacial tension of appropriate additional proportion adjustable slag, to reach
Improve the purpose of appearance of weld, weld metal can also be purified simultaneously, reduce crack sensitivity.The addition of magnesia is less than 31%
Time, the spreadability of slag Resistance of Weld Metal is deteriorated, and appearance of weld is bad, and fire check sensitivity increases；The addition of magnesia is big
In 33% time, the viscosity of slag increases, and spreadability and the removability of slag of weld metal are all deteriorated；
Fluorite: Main Function is slag making, the fusing point of appropriate additional proportion adjustable slag and viscosity, increase its mobility, to reach
To activation molten bath, improve de-slag and the purpose of dehydrogenation.When fluorite addition is less than 3%, slag is more glutinous, the spreadability of weld metal
Poor, de-slag is more difficult, and impression easily occurs in face of weld；When addition is more than 6%, viscosity coefficient of dross is less than normal, and appearance of weld is deteriorated,
The defects such as undercut easily occur；
Aluminium oxide: Main Function is slag making, appropriate addition can improve the mobility of slag, make the protection of slag Resistance of Weld Metal more
Add fully.When the addition of aluminium oxide is less than 12%, the mobility of slag is deteriorated, and the covering of slag Resistance of Weld Metal is insufficient, weldering
It is seamed into deformation poor；When addition is more than 15%, the viscosity of slag increases, and formability and the removability of slag of weld metal are all deteriorated；
Calcium aluminate: Main Function slag making, appropriate fusing point and the interfacial tension that can reduce slag that add, raising weld seam paving formability
And the removability of slag.The addition of calcium aluminate is less than 2%, and the ripple of weld metal is relatively thick, and the removability of slag is more difficult；When addition is more than 4%,
The spreadability of slag Resistance of Weld Metal is deteriorated, and the defects such as undercut easily occurs；
Quartz: Main Function is slag making, the appropriate activity adding the viscosity that can adjust slag and increase slag.Quartz addition
During less than 10%, the spreadability of weld metal be deteriorated in, at the scrap (bridge) of weld metal, transition is poor；When addition is more than 14%, weldering
The removability of slag of seam metal is deteriorated；
Cryolite: Main Function is slag making, the appropriate fusing point that can reduce slag that adds, the activity of raising slag, improve weld seam
The shaping of metal and sprawling.When the addition of cryolite is less than 3%, the spreadability of weld metal is deteriorated；Addition is more than 5%
Time, weld metal shapes and is deteriorated, and easily occurs scraping slag phenomenon in welding process；
Carboxymethyl cellulose: Main Function is to reduce solder flux pine dress ratio, improves welding usability.The addition of CMC is less than 1%, weldering
The pine dress ratio of agent is bigger than normal, and welding usability is poor；When addition is higher than 3%, solder flux pelletize is poor；
Crome metal: Main Function is transition alloy elements.Crome metal addition is higher than 3%, and in weld metal, ferrite content is inclined
Height, easily causes σ phase to separate out, and deteriorates the bending resistance of weld metal；When addition is less than 2%, the anti intercrystalline corrosion of weld metal
Degradation；
Metal molybdenum: Main Function is transition alloy elements.When metal molybdenum addition is less than 3%, the bending property of weld metal becomes
Difference；When addition is higher than 4%, the bending property of weld metal is also deteriorated；
Pure sodium silicate: Main Function is bonding powder body.When waterglass addition is less than 21%, it is impossible to complete solder flux pelletize；Add
When amount is more than 24%, powder body becomes bulk or bulk, also cannot be carried out pelletize.
Beneficial effect: the present invention, compared with existing solder flux, has the advantage that
1) solder flux of the present invention is specially to join EQ309LMo, EQ316L welding to use, and is not existing general type solder flux:
2), after 690 DEG C × 22h heat treatment, anti-side is more excellent to bending property and corrosion among crystalline grains；
3) weld metal is sprawled wider, and overlap joint is smooth, and the removability of slag is good, and comprehensive welding usability is more excellent.
