Description
реплава. Шлак нагреваетс графитовыми электродами, оиущеннымп в шлаковую ванну. Удельна приведенна мощность, т. е. отношение электрической мош.ности к объему шлаковой ванны, составл ет 0,8- 1,0 ВА/см-1 Слиток непрерывно врашают вокруг его оси со скоростью 1 оборот в минуту. Оплавление слитка на глубину 30 мм в данных услови х составл ет 9- 12 мин. После оплавлени всей поверхности слиток удал ют и начинают обрабатывать новый. После заполнени сливают и после затвердевани удал ют металл. При применении тигл емкостью 5 м п объеме шлака 2 м можно обработать до 40 слитков вакуумного дугового переплава.the float. The slag is heated by graphite electrodes impregnated into the slag bath. The specific reduced power, i.e., the ratio of electric mosh.nost to the volume of the slag bath, is 0.8-1.0 VA / cm-1. The ingot continuously turns around its axis at a speed of 1 revolution per minute. The melting of the ingot to a depth of 30 mm in these conditions is 9 to 12 minutes. After the entire surface has been melted, the ingot is removed and a new one is started to be processed. After filling, the metal is drained and after solidification the metal is removed. When using a crucible with a capacity of 5 m p of a slag volume of 2 m, up to 40 ingots of vacuum arc remelting can be processed.
Использование изобретени дл очистки поверхности слитков вакуумного дугового переплава позвол ет получать поверхность с высокой степенью чистоты. Значительно снижаютс затраты на обработку слитков вследствие многократного использовани шлака и использовани всех отходов металла .Using the invention to clean the surface of ingots of vacuum arc remelting allows to obtain a surface with a high degree of purity. The cost of processing ingots is significantly reduced due to the repeated use of slag and the use of all metal waste.
