Изобретение относитс к черной металлургии .This invention relates to the steel industry.
Известен способ раскислени прецизионных сплавов, включающий обработку расплава кальцием. Однако предварительное раскисление металла алюминием или титаном приводит к резкому сннженню служебных характеристик магнито;м гких материалов .There is a known method for deoxidizing precision alloys, which includes melt processing with calcium. However, the preliminary deoxidation of metal with aluminum or titanium leads to a sharp decrease in the service characteristics of magnetically soft materials.
Дл повышени качества сплавов и выхода годного предлагаетс перед присадкой кальци за 2-25 мин до выпуска металла из печи вводить цирконий в количестве 0,05- 0,4% от веса садки.To improve the quality of alloys and yield, it is proposed to add zirconium in an amount of 0.05-0.4% by weight of the charge before the calcium additive is added 2-25 minutes before the metal is released from the furnace.
Пример. Сплав 50Н выплавл ют в основной индукционной печи на чистых материалах . За 5-7 мин до выпуска металла ввод т силикоцирконий из расчета 0,1 циркони , а за 3-5 мин до вЫпуска - металлический кальций из расчета 0,1% кальци . Разливку провод т в атмосфере оргона .Example. Alloy 50N is melted in the main induction furnace on pure materials. Silicone-zirconium at a rate of 0.1 zirconium is injected 5–7 minutes before the metal is released, and calcium metal is used at a rate of 0.1% calcium 3–5 minutes before the release. The casting is carried out in an orgone atmosphere.
Количество кислорода и неметаллических включений снижаетс в 1,5-2,5 раза; выход годного увеличиваетс на 5-6%.The amount of oxygen and non-metallic inclusions decreases 1.5-2.5 times; yield is increased by 5-6%.
