Description
Известен флюс дл сварки сталей и сплавов , содержащий криолит, окись кремни , плавиковый шпат, окись марганца, причем марганец и кремний могут вводитьс во флюс в виде силикомарганца.Known flux for welding steels and alloys containing cryolite, silica, fluorspar, manganese oxide, and manganese and silicon can be introduced into the flux as silicomanganese.
Чтобы повысить качество сварных соединений и снизить температуру плавлени флюса, предлагают следующий его состав, %: криолит28To improve the quality of welded joints and reduce the melting point of the flux, its following composition is proposed,%: cryolite28
кремнеземдо 8silica 8
фтористый кальций 60-65calcium fluoride 60-65
Предложенный флюс имеет более низкую температуру плавлени , что позвол ет использовать его дл сварки относительно легкоплавких металлов, например чугуна.The proposed flux has a lower melting point, which allows it to be used for welding relatively low-melting metals such as cast iron.
В жидком состо нии флюс способствует наилучшему удалению шлаковых включений в процессе кристаллизации сварочной ванны.In the liquid state, the flux promotes the best removal of slag inclusions in the process of crystallization of the weld pool.
Пред мет изобретени Present Invention
Флюс дл сварки, содержащий криолит, фтористый кальций, кремнезем, отличающийс тем, что, с целью повышени качества сварных соединений и снижени температуры плавлени флюса, его состав вз т в следующем соотношении (в о/о):Flux for welding, containing cryolite, calcium fluoride, silica, characterized in that, in order to improve the quality of welded joints and reduce the melting temperature of the flux, its composition is taken in the following ratio (o / o):
криолит28cryolite28
