Subject to the meaning stated.
Details are as follows for the effect of stainless steel filament submerged-arc welding low temperature of the present invention sintered flux each component:
In general, main ingredient CaF2The main function of fluorite be slag making, conduction and dehydrogenation, while being also electroslag mistake
The key that journey is gone on smoothly.With fluorite/CaF2The conductivity of the increase of adding proportion, slag is gradually increased, when conductivity increases
When greatly to a certain extent, the resistance heat of generation just can guarantee the quick foundation and the stabilization in electroslag molten bath of Electroslag Process, thus
Guarantee the stabilization of entire electroslag welding process.But excessive fluorite/CaF2It can make that conductivity is excessively high, viscosity coefficient of dross reduces, influence electricity
The stability and welding bead Forming Quality of slag weldering.
In general, main ingredient Al2O3The addition of white fused alumina can adjust the physical property of solder flux slag, adjust welding
Electric arc and Electroslag Process in the process, and improve skull and appearance of weld to a certain extent.
In general, main ingredient includes CaO, SiO2The major function of wollastonite be that balance and is made solder flux pH value
The effect of slag.The basicity of welding slag can be improved in CaO, improves the mechanical performance of overlay cladding deposited metal.SiO2Reduce slag
Basicity, but have the function of adjusting slag fluidity, refinement molten drop and improve appearance of weld.
In general, the magnesia of main ingredient MgO is added mainly as slag former, it can improve the basicity of slag, increase
The gas permeability and surface tension of slag, improve the removability of slag of solder flux.
In the present invention, the addition of alloyed powder (for example, nichrome powder, is also known as nickel chromium triangle iron powder in the present invention)
Have the function of the effective alloying element dilution of supplement and scaling loss.
It in the present invention, is the quality for guaranteeing solder flux, binder uses potassium sodium than for the waterglass of 1~2:1, at room temperature
Baume degrees is about 40~43, and dry powder is granulated by wet mixing, then drying, by high temperature sintering after screening, then through cooling, promotion,
Screening is packed and is made, and flux particle size controls within the scope of 20~80 mesh.
The stainless steel filament submerged-arc welding low temperature sintered flux that the present invention designs, the dry grinding fluorite main component used are
CaF2；Magnesite clinker main component is MgO；The main component of white fused alumina is Al2O3；The predominantly CaO and SiO of wollastonite2Composition
Complex chemical compound.
Sintered flux according to the present invention is granulated, dries by stirring evenly the ingredient component with waterglass
It is dry then manufactured through sintering.Sintered flux according to the present invention is equal by stirring the ingredient component and waterglass
It is even, it is granulated, dries, screening, then it is manufactured through 700-800 DEG C of sintering (such as being sintered 0.5-2 hours, for example, about 1 hour).
Nickel of the present invention hereafter in alloyed powder used in each embodiment is added in the form of metallic nickel, these embodiments exist
It is to be carried out with 12~15m/h of speed of welding when " d) Performance ", if welding bead formability can be generated significantly not by improving speed
The influence of benefit.For the present inventor referring to the test of 1~embodiment of Examples below 6, different is only by the nickel in wherein alloyed powder
It is changed to addition and the constant rate of nickel in the alloy in the form of nitrogenizing metallic nickel, it has been unexpectedly discovered that result is aobvious
Show that properties still are able to reach the finger of each solder flux of 1~embodiment of embodiment 6 under conditions of 25~28m/h of speed of welding
Mark, after the nitridation metal nickel powder for the nickel amount such as the nickel in embodiment 1 but alloyed powder is changed to, tensile strength 615Rm/
Mpa, elongation (A/%) are 41, -196 DEG C of impact value (AKv/ J) it is 67.For this purpose, in one embodiment of the invention, it is described
Nickel in alloyed powder is added in the form of nitrogenizing metal nickel powder.
To improve weld metal welding usability, -196 DEG C of low-temperature flexibilities, the main means that the present invention uses are:
1, the main means of -196 DEG C of low-temperature flexibilities of weld metal are improved: adding alloying element, into solder flux to guarantee to weld
The reasonable alloying element of transition, preferably controls ferrite content, the mainly preferred iron of the addition of the above alloying element in seam
Alloy ferrochrome is as interim form, because it is not decomposed during sintering, shifts carbon, nickel in a predictive manner containing ferrochrome
Element transition as metallic particles；Raw material quality is improved, bring objectionable impurities in raw material is reduced, improves the pure of weld seam
Cleanliness；Inventive formulation can effectively inhibit the harmful elements such as H, O to weld seam transition, effectively enhance de- S, P effect of weld seam
Fruit.
2, improve the main means of welding technological properties: with MgO, Al2O3As the main slag former of adjustment basicity, control
The alkalinity ranges 1.8-2.1 of solder flux makes it have the good welds processing performance advantage of low alkalinity slag system.Inventive formulation can
Viscosity, surface tension, the mobility etc. of slag are effectively improved, so as to improve the surface flatness of weld seam and the removability of slag of skull
Can, it ensure that the surface quality of weld seam.
Technical solution of the present invention provides some clear advantages compared with prior art and effect, such as, but not limited to
Lower at least one aspect:
1, the rational allocation of the present invention ratio of solder flux each component, using a kind of sintered flux system that basicity is moderate,
Viscosity, surface tension and the mobility for preferably having adjusted slag stablize arc burning during solder flux welding, and postwelding takes off slag
It is easy, welding bead edge transition is smooth, and welding technological properties is also excellent under the harsh conditions such as groove, narrow gap.
2, inventive formulation, which can effectively inhibit, inhibits the harmful elements such as H, O to weld seam transition, and S, P increment are low, protect
It is few etc. the degree of purity of weld metal, austenite former scaling loss are demonstrate,proved, -196 DEG C of low-temperature impacts for improving weld metal are tough
Property.
3, the present invention is matched with ER308L welding wire, and since its weld seam has lower ferrite content, weld metal has
Higher low-temperature impact toughness, charp impact value AKv(- 196 DEG C) mean value reaches 63J, and impact value is relatively stable.
