| titleOfInvention | Seamless flux-cored wire for all-position welding of austenite ultralow-temperature steel and preparation method thereof |
| abstract | The invention discloses a seamless flux-cored wire for all-position welding of austenitic ultralow-temperature steel, which consists of a low-alloy steel sheath and flux-cored powder, wherein the flux-cored powder accounts for 38% of the total weight of the seamless flux-cored wire, and the flux-cored powder comprises the following components in percentage by mass: 50-60% of electrolytic manganese metal, 16-20% of nickel powder, 6-10% of aluminum-magnesium alloy, 1-3% of silicon carbide, 3-5% of tungsten carbide, 5-10% of quartz and the balance of pretreated mixed powder, wherein the sum of the mass percentages of the components is 100%, and the pretreated mixed powder comprises the following pretreated components in percentage by mass: 50-70% of zirconium dioxide, 17-26% of potassium carbonate, 10-20% of crystalline flake graphite, 1-2% of sodium fluoride and 1-3% of rare earth fluoride. The seamless flux-cored wire is mainly used for building LNG ships and storage tanks made of high-manganese austenitic ultralow-temperature steel, and is good in all-position welding manufacturability and excellent in low-temperature toughness. |
