Изобретение относитс к сварочному производству, в частности к флюcafji дл электрошлаковой сварки, преимущественно легких металлов в сильных внешних магнитных пол х, используемых в.различных отрасл х промышленности , например, в цветной металлургии дл электрошлаковой сварки алюминиевых шинопроводов электролизеров ..The invention relates to welding production, in particular, fluxesfes for electroslag welding, mainly light metals in strong external magnetic fields used in various industries, for example, in non-ferrous metallurgy for electroslag welding of aluminum busbars of electrolyzers.

Недостатком известных флюсов вл етс их мала температура кипени , что ведет к образованию в шлаковой ванне сильных турбулентных потоков при сварке во внешнем магнитном поле. Это, в свою очередь, значительно снижает стабильность процесса сварки за счет выплесков шлаковой ванны из зазора, а также предопредел ет по вление шлаковых включений в сварных швах. Кроме того, низка температура кипени вход щих в их состав компонентов не позвол ет доводить температуру шлаковой ванны до величины, необходимой дл полногоA disadvantage of the known fluxes is their low boiling point, which leads to the formation of strong turbulent flows in the slag bath during welding in an external magnetic field. This, in turn, significantly reduces the stability of the welding process due to splashes of the slag bath out of the gap, and also predetermines the appearance of slag inclusions in the welds. In addition, the low boiling point of its constituent components does not allow the temperature of the slag bath to be brought up to the value required for complete
проплавлени свариваемых кромок.Повышение же теплоемкости шлаковой ванны за счет увеличени ее объема недопустимо при сварке во внешнем магнитном поле, так как это приводит к увеличению взаимодействи внешнего магнитного пол с магнитным полем, создаваемым сварочным током, к нарушению стабильности процесса. penetration of welded edges. Increasing the heat capacity of the slag bath by increasing its volume is unacceptable when welding in an external magnetic field, since this leads to an increase in the interaction of the external magnetic field with the magnetic field created by the welding current, to a violation of process stability.
Целью изобретени вл етс создание флюса,обеспечивающего повышение стабильности процесса сварки во внешнем магнитном поле и улучшение пррплавлени свариваемых кромок .The aim of the invention is to create a flux, which ensures an increase in the stability of the welding process in an external magnetic field and an improvement in the welding of the edges being welded.
Поставленна цель достигаетс тем что флюс дополнительно содержит фтористый калий при следующем соотношеНИИ компонентов, весД:The goal is achieved by the fact that the flux additionally contains potassium fluoride at the following ratio of components, weight:
