Изобретение относитс к области .металлу1ргии и может быть использовано дл улучшени .качества металла при обработке его в ковше.The invention relates to the field of metal and can be used to improve the quality of the metal when it is processed in a ladle.
Известен синтетический шлак дл рафинировани металла, имеющий следующий состав , вес. %:Synthetic slag for metal refining, having the following composition, is known. %:
SiOa42,7SiOa42,7
АЬОз10,3ABOS 10.3
СаО19,22CaO19.22
МпО8,85MpO8,85
МазО+КзО9,52Mazo + KzO9,52
ВгОз5,52.Br0.52.
Предлагаемый синтетический шлак дл рафинировани и модифицировани металла отличаетс от известного тем, что дл обеспечени высокой рафинирующей способности и жидкоподвижности шлака, а также улучшени структуры и механических свойств металла компоненты вз ты в следуюшем соотношении , вес. %:The proposed synthetic slag for refining and modifying the metal differs from the well-known one in that in order to ensure high refining ability and liquid mobility of the slag, as well as improving the structure and mechanical properties of the metal, the components are taken in the following ratio, weight. %:
Известь40-50Lime40-50
Глинозем30-40Alumina 30-40
Кремнезем5-15Silica 5-15
Борный ангидрид5-15.Boric anhydride 5-15.
Приготовление шлака производитс путем переплавлепи в электропечи шихты, состо щей из известн ка (мела), глинозема, маршалита и борной кислоты.Slag preparation is carried out by remelting in a charge electric furnace consisting of limestone (chalk), alumina, marshalite and boric acid.
