Пример, В завалку с шихтой давали 2ОО кг известч и ЗОО кг техиического глинозема. Расплавление шихты н окислительное рафинирование проводили в соответствии с действующей инструкцией.. Шлак окислительного периоца, скачивали иачисто, и на зеркало металла присаживали метал- лодобавки. Затем наводили шлак из извести и плавикового шпата и проводили раскисление .Example, In the filling with the charge was given 2OO kg lime and ZOO kg technical alumina. The charge was melted down by oxidative refining in accordance with the current instruction. The oxidative perox slag was downloaded, clean, and metal additives were placed on the metal mirror. Then, slag was made from lime and fluorspar and deoxidation was carried out.

Продолжительность рафиннровки составл ла около 1 часа, Металл вьшускали в ковшThe duration of the refining was about 1 hour. The metal was released into the ladle.

Вьшлавленный металл удовлетвор ет требовани м технических условий и сдан потребителю, а по уровню свойств, содержанию газов в неме- J таллических включений не уступает металлу вакуумно-дугового переплава.with slag and purged with argon. The alloy metal satisfies the requirements of the technical conditions and is handed over to the consumer, and in terms of properties, the content of gases in non-metallic inclusions is not inferior to the metal of vacuum-arc remelting.
