The each component design principle of three submerged-arc welding Special pad solder flux of FCB method in the present invention:
MgO main function is slag making, improves the fusing point of slag, so as to improve appearance of weld, reduces the reinforcement of weld seam.This hair
In bright embodiment, MgO is added in the form of fused magnesite.The amount ranges of fused magnesite are 26~30 parts, and dosage is less than
At 26 parts, solder flux fusing point is lower, and welding slag is diluter, and weld seam is easy leakage and falls into；When its dosage is greater than 30 parts, flux basicity is excessive, weld seam
De- slag is difficult, and slag fusing point is too high, and weld seam protection is bad.
Al2O3Main function is basicity, setting temperature and the viscosity for adjusting slag, to preferably protect weld seam, and is improved
Slag detachability.In the present invention, Al2O3Amount ranges be 10~15 parts, when dosage is less than 10 parts, slag is diluter, and molten iron can be from
Sealing run evolution causes sealing run molding bad；When its dosage is greater than 15 parts, slag is relatively viscous, and weld seam easy to form is ventilative
The defects of bad and generation slag inclusion.
BaO mainly plays slag making, its presence can improve the removability of slag of weld seam.In the present invention, the dosage of BaO
Range is 5~10 parts, when dosage is less than 5 parts, and the de- slag of slag is bad, and processing performance is poor；When its dosage is greater than 10 parts, slag alkali
Degree is big, and welding technological properties is poor.
Li2O mainly plays a part of to reduce solder flux moisture absorption, its presence can make solder flux moisture absorption low, weld
When reduce weld seam in diffusible hydrogen, to reduce crack sensitivity.In the present invention, Li2The amount ranges of O are 4~5 parts,
When dosage is less than 4 parts, solder flux moisture absorption is high, and bead crack is sensitive；When its dosage is greater than 5 parts, processing performance is poor.
High-temperature resin, which mainly passes through resin heating process, makes it generate solidification, prevents molten iron from leaking, and guarantees weld seam
Molding.In the present invention, the amount ranges of high-temperature resin are 0.5~1.0 part, when dosage is less than 0.5 part, in the welding process
Molten iron is easy leakage, causes appearance of weld poor；When its dosage is greater than 1.0 parts, weld porosity is more.High temperature resin of the present invention is heat
Solidity phenolic resin, 150 degree of solidification temperature or more.
Compared with prior art, beneficial effects of the present invention:
(1) three submerged-arc welding Special pad solder flux of this FCB method provided by the invention are suitable by being added into solder flux
MgO and Al2O3It improves the fusing point of welding slag, and uses TiO2Substitute part SiO2The basicity of solder flux and the viscosity of slag are adjusted, is made
Weld seam has good appearance of weld and weld reinforcement, and weld reinforcement is no more than 3mm, and reduces the Si content in weld seam；And
Due to SiO in solder flux2Content is less, to improve the toughness and crack resistance of weld seam.
(2) it joined appropriate high-temperature resin in three submerged-arc welding Special pad solder flux of this FCB method provided by the invention, lead to
Crossing high-temperature resin heating process makes it generate solidification, prevents molten iron from leaking, ensure that appearance of weld.
