Abstract

Описан сосуд прямого плавления для оперирования процессом прямого плавления на основе ванны расплава при наличии давления в сосуде. Сосуд имеет подогревательную камеру для непрерывного выпуска жидкого металла из сосуда. Подогревательная камера имеет соединительный канал, который проходит сквозь боковую стенку сосуда внутрь нее. Соединительный канал выполнен для ослабления влияния внезапных изменений давления в сосуде на поток жидкого металла в подогревательной камере, которые могут приводить к нежелательному выбросу жидкого металла с подогревательной камеры. Соединительный канал также выполнен так, что жидкий металл не затвердевает в нем в течение минимум 6 часов, когда он не выпускается из сосуда в подогревательную камеру сквозь соединительный канал.
