Abstract

The invention provides high-basicity and high-tenacity submerged-arc welding flux applicable to the technical field of welding materials. The high-basicity and high-tenacity submerged-arc welding flux comprises, by weight, 23-26 parts of MgO, 13.5-21 parts of CaF2, 14-20 parts of Al2O3, 15-22 parts of TiO2, 4-8 parts of SiO2, 11-18 parts of BaO, 3-5 parts of CaO, 0-3 parts of MnO, 0.1-0.5 part of B2O3. The lower limit of drying temperature before use of the submerged-arc welding flux is 300 DEG C. By the high-basicity and high-tenacity submerged-arc welding flux, low-temperature impact tenacity of welding seams is improved, and the welding seams have excellent technical welding performance; via reasonable selection and proportional matching of raw materials, the prepared welding flux is low in moisture absorption rate, drying temperature before use of the welding flux is reduced, and energy consumption is reduced as well.

Description

technical field

[0001] The invention belongs to the field of welding materials, in particular to a high-alkalinity and high-toughness submerged arc welding flux for marine engineering and a preparation method thereof. Background technique

[0002] With the gradual reduction of land resources, countries all over the world are actively developing resources in the ocean field. There are a large number of oil, gas and wind resources in my country's sea areas. They are marine energy necessary for the development of the national economy. Marine development has become an important part of the national development plan. During the "13th Five-Year Plan" period, my country invested 350 billion yuan to vigorously develop ocean transportation and High steel grade wide and thick steel plates for offshore oil industry, construction of drilling platforms and other offshore engineering. Structural steel for marine engineering (marine steel) has become a key research and development object f...
