Abstract

The invention relates to a soldering flux and discloses a soldering flux for submerged arc horizontal position welding of a steel containment. The soldering flux for submerged arc horizontal position welding of the steel containment comprises the following components of, by mass, 6-18% of SiO2, 22-40% of MgO, 12-28% of Al2O3, 15-30% of sigma CaO, 0.5-4% of MnO, 0.5-2% of Na2O, 0.2-2% of K2O, 0<TiO2<=3%, 0<Fe2O3<=3.0%, 0<S<=0.030%, and 0<P<=0.030%. Compared with soldering fluxes in prior art, the submerged arc soldering flux for submerged arc horizontal position welding of the steel containment is special for welding the steel containment for nuclear power and has the advantages of good welding manufacturability, slag removal effects and mechanical properties and attractive shaping.

Description

Technical field [0001] The invention relates to a flux, in particular to a flux for submerged arc transverse welding of steel containment, a preparation method and a welding method using the flux in conjunction with a welding wire CHW-S62HRF. Background technique [0002] Under the current situation of large-scale application of clean energy such as nuclear power in my country, nuclear power projects will be the focus of my country’s future clean energy development. The development of submerged arc welding materials for nuclear power steel containment SA738Gr.B steel and other materials will be very large. In the current nuclear power products, the existing flux has high cost and poor performance after welding. Summary of the invention [0003] One of the objectives of the present invention is to provide a flux for submerged arc transverse welding of steel containment. The flux used for submerged arc transverse welding of steel containment is specially used for steel containment SA...
