Известен способ выплавки слитка вакуумнодуговым переплавом расходуемого электрода, в который ввод т при его выплавке алюмиппй в количестве 1,2-2 кг/т.There is a known method for smelting an ingot by vacuum-arc remelting of a consumable electrode, into which aluminum is introduced in the amount of 1.2-2 kg / ton during its smelting.
Цель изобретени - получение высококачественного слитка с минимальным количеством неметаллических включений и газов.The purpose of the invention is to obtain high-quality ingot with a minimum amount of non-metallic inclusions and gases.
Дл этого по предлагаемому способу металл расходуемого электрода выплавл ют без применени сильных раскислителей, а во врем переплава в вакуумной дуговой печи в жидкую ванну металла в кристаллизаторе ввод т активный раскислитель (злюмитш, титан, цирконий и др.).For this, according to the proposed method, the metal of the consumable electrode is smelted without the use of strong deoxidizing agents, and during melting in a vacuum arc furnace, the active deoxidizing agent (Zlumitsh, titanium, zirconium, etc.) is introduced into the liquid metal bath.
Добавки ввод т порциопно или непрерывно.Additives are administered portionally or continuously.
Пред.чагаемьи способ позвол ет получить слиток плотной структуры с остаточным содержапнем кислорода 6,001-0,002%.The previous method allows to obtain an ingot of a dense structure with a residual oxygen content of 6.001-0.002%.
Предмет пзобретени Subject matter
Способ выплавки слитка вакуумпо-дуговым переплавом расходуемого электрода с прпмеиепием высокоактивного раскислител , отлич а ю HI и и с тем, что, с целью повышени качества слигка, раскислитель ввод т в нроцессе нереплава пепосредствен110 в жндкую ванну в кристаллизаторе.The method of smelting an ingot by a vacuum-arc remelting of a consumable electrode with the use of a highly active deoxidizing agent, is different from HI, and in order to improve the quality of the ingot, the deoxidizing agent is introduced into the solid bath in the crystallizer in the process of non-rafting.
