Изобретение оТ НО1ситс  ,к обласги металлургии Ц вет1ных металло;в и касаетс  электролита дл  получени  алюмокремниввых сплаво1В электролизом ион«ых расплаеоВ.The invention of HOCS, in the field of metallurgy of wind metals, relates to the electrolyte for the production of aluminum-silicon alloys, by electrolysis of ion melts.

Известен электрол-ит дл  получени  алюмо1кремииевы ,х :спла:во1в электролизо-м ионных расплавов, содержащий 30-60 вес. % кремнефторида натри  и 20-50 вес. % хлорида натри . KpOiMe того, ои содержит хлорид кали  IB количестве 10-20 вес. % и малолетучие комплексные фториды в количест1ве 3- 13 вес. %.The known electrolyte for the production of aluminum, x: al: in electrolysis of ionic melts, containing 30-60 weight. % sodium silicofluoride and 20-50 wt. % sodium chloride. KpOiMe addition, it contains potassium chloride IB amount of 10-20 weight. % and low volatile complex fluorides in the amount of 3-13 weight. %

Недо€тат1ком из ве1стного электролита Я1вл етс  Высока  температура процесса (950- 1000°С), при которой составные части электролита претерпевают тер.мичеокую диссоциацию с выделением газообразных продуктов , содержащих фтор и кремиий.Low temperature of electrolyte electrolyte H1 High process temperature (950–1000 ° C) at which constituents of electrolyte undergo thermal dissociation, releasing gaseous products containing fluorine and cremia.

Целью изобретени   вл етс  снижение температуры процесса электролитического получени  алюмо1крем,ние1вых сплавов.The aim of the invention is to reduce the temperature of the electrolytic production process of aluminum silicon, alloying.

Подставленна  цель достигаетс  тем, что в cocTaiB предлагаемого электролита введены криолит и фторнд натри  при следующе-м СООТНОшеи-ИИ компонентов, вес. %:The substituted goal is achieved by the fact that cryolite and sodium fluoride are introduced into cocTaiB of the proposed electrolyte at the following components, AI weight. %:
