Флюс изготавливают следующим образом .Flux is made as follows.
Обезвоженные и взвешенные компоненты ишхты флюса тщательно перемешивают и засыпают в графитовый тигель (графит марки ГМЗ), который устанавливают с равномерным зазором в кольцевой индуктор высокочастотной плавильной установки. После выведени установки в режим производ т плавку флюса. Готовность расплава определ ют визуально и отбором пробы на вольфрамовый пруток. Полна прозрачность расплаваThe dehydrated and weighted components of the Ishkhta flux are thoroughly mixed and poured into a graphite crucible (graphite grade GMZ), which is installed with a uniform gap in the ring inductor of a high-frequency smelter. After removing the unit to the mode, the flux is melted. The melt readiness is determined visually and a sample is taken for a tungsten rod. Full melt transparency
: л ёШай отделймость от вольфрамового прутка однородной затвердевшей шлаковой корки свидетельствуют о готрвности фхпоса. Расплавленный флюс выливают в горизонтальную изложницу с зеркалом из нержав оощей стали Х18 Н9 и: L ySHY separability from the tungsten rod of a homogeneous hardened slag crust testify to the readiness of the phpos. The molten flux is poured into a horizontal mold with a stainless steel mirror H18 H9 and
после его остывани производ т дробление до требуемой гранул ции.after it has cooled, crushing is performed to the desired granulation.
Примеры выполнени изобретени представлены в табл.1Examples of the invention are presented in table 1.
