METHOD OF MIXING FLUX BED IN ELECTROSLAG REMELTING OF CONSUMABLE ELECTRODE

FIELD: metallurgy.SUBSTANCE: in compliance with this method, flushing is performed by the mix of nitrogen with oxygen at flow rate of 0.7-1.2 l per one kg of remelted consumable electrode at 1.43-2.45 l/min while amount of oxygen in said mix is kept equal to 0.5-10 vol. % of total amount of mix blow...

More Information
Summary:FIELD: metallurgy.SUBSTANCE: in compliance with this method, flushing is performed by the mix of nitrogen with oxygen at flow rate of 0.7-1.2 l per one kg of remelted consumable electrode at 1.43-2.45 l/min while amount of oxygen in said mix is kept equal to 0.5-10 vol. % of total amount of mix blown into slag bed.EFFECT: power savings, higher quality of cast ingot. Изобретение относится к спецэлектрометаллургии и может быть использовано при изготовлении слитка стали электрошлаковым переплавом расходуемого электрода. В способе продувку ведут смесью азота с кислородом с расходом 0,7-1,2 л на 1 кг переплавляемого расходуемого электрода при 1,43-2,45 л/мин, а количество кислорода в смеси поддерживают в пределах 0,5-10 об.% от общего количества вдуваемой в шлаковую ванну смеси. Изобретение позволяет снизить энергозатраты, повысить температурную стабильность шлаковой ванны, эффективность рафинирующего действия шлака и качества поверхности выплавляемого слитка.
