Description
Изобретение относитс к области производства сталей и сплавов и может быть использовано при разливке их в изложницы.The invention relates to the production of steels and alloys and can be used for casting them into molds.
Известны экзотермические шлакообразующие смеси, в которых экзотермическими компонентами вл ютс алюминиевыр порошок, окислителем - натриева селитра, а шлакообразующими составл ющими - плавиковый шпат, силикатна глыба, доменных печей .Exothermic slag-forming mixtures are known, in which the exothermic components are alumina powder, the oxidizing agent is sodium nitrate, and the slag-forming components are fluorspar, silicate lump, blast furnaces.
Недостатком известных смесей вл етс наличие сцеплени шлака с чугуном изложниц. /Предлагаемый состав отличаетс от известного тем, что в качестве шлакообразующего компонента использован отработанный в электрошлаковых печах флюс типа АНФ-6 и АНФ-7, который имеет следуюш;ий химический состав:A disadvantage of the known mixtures is the presence of slag adhesion to cast iron of molds. The proposed composition differs from the well-known fact that the flux used in electroslag furnaces of the ANF-6 and ANF-7 types, which has the following chemical composition, is used as the slag-forming component;

Предлагаема смесь имеет следующий состав , вес. ч.:The proposed mixture has the following composition, weight. including:
Алюмомагниевый порошок 4-6 Алюминиевый порошок8-12Aluminum Magnesium Powder 4-6 Aluminum Powder8-12
Селитра натриева 10-15Sodium Nitrate 10-15
Силикатна глыба15-30Silicate clump15-30
Плавиковый шпат10-25Fluorspar10-25
Доменный шлак от передельных чугунов15-50 Смесь такого состава позвол ет значительно улучшить поверхность слитков и проката, а также уменьшает сцепление шлака с чугуном изложниц, что значительно облегчает чистку изложниц.Blast furnace slag from pig iron 15-50 A mixture of this composition can significantly improve the surface of the ingots and rolled products, as well as reduce the adhesion of the slag with the cast iron of the molds, which greatly facilitates cleaning the molds.
Кроме того, применение флюсов типа АНФ-6 и АНФ-7, которые вл ютс отходами производства, спижает стоимость экзотермической смеси.In addition, the use of fluxes of the ANF-6 and ANF-7 types, which are production wastes, decreases the cost of the exothermic mixture.
