Description

Изобретение охносито  в процессам плавни магни  и его сплавов с применением флюсов.The invention is in the process of flux magnesium and its alloys using fluxes.

Дл  плавки магни  и его сплавов примен ютс  хлористые флюсы, например ВИ2, ФЛ5-3, ФЛЮ, основой которых  вл ютс  хлористые соли магни , вали  бари .Chloride fluxes, for example VI2, FL5-3, FLU, which are based on magnesium chloride salts, were used to melt magnesium and its alloys.

Недостатком хлористых флюсов  вл етс  возможность их попадани  в отливки из магниевых сплавов, что вызывает флюсовую коррозию и делает издели  непригодными дл  эксплуатации.A disadvantage of chloride fluxes is the possibility of their falling into magnesium alloy castings, which causes flux corrosion and makes the products unsuitable for use.

Известны бесхлоридные флюсы дл  обработки расплавленного магни  и его оп авов, содерхащие фтористый алюминий и фтористый кальций. Например , один из извеотных флюсов оодермт 20-27% 55 ористого алюмини , до S фтористого кальци , 25-40 криолита и 30-6С борного ангидрида. I Однако флюс указанного состава не позвол ет получить отливки без флюсовых включений и с достаточно высокой коррозионной стойкостью.Chloride-free fluxes are known for treating molten magnesium and its opums containing aluminum fluoride and calcium fluoride. For example, one of the known fluxes of oodermt is 20-27% 55 of anoxide aluminum, up to S calcium fluoride, 25-40 cryolite and 30-6C boric anhydride. I However, the flux of the specified composition does not allow to obtain castings without flux inclusions and with sufficiently high corrosion resistance.

Предложенный флюс отличаетс  тем, что в него введен .фтористый цинк при следующем соотношении компонентов, вес.:The proposed flux is characterized in that zinc fluoride is added to it in the following ratio of components, weight:

Фтористый алюминий 30-70 Фтористый цинк 5-25 Фтористый кальций Остальное Данный флюс обеспечивает получение отливок без флюсовых включений и с более высокой коррозионной стойкостью за счет того, что флюс указанного состава имеет более высокую в зкость, плотность и малую поверхностную активность по сравнению с известными хлорис тыми и бесхлоридными флюсами. .Aluminum fluoride 30-70 Zinc fluoride 5-25 Calcium fluoride Else This flux provides castings without flux inclusions and with higher corrosion resistance due to the fact that the flux of this composition has a higher viscosity, density and low surface activity compared with the known chlorine and chloride free fluxes. .
