Abstract
Описан способ непрерывного литья, при котором расплав (4) подается в рамочный кристаллизатор через верхнее отверстие кристаллизатора при помощи сопла (5), имеющего по меньшей мере два противолежащих выхода (9), до тех пор, пока уровень поверхности (10) расплава (4) не достигнет устойчивого положения над выходами (9), и при котором в устойчивом состоянии, по меньшей мере, поверхностно затвердевшая отливка (13) извлекается через донное отверстие кристаллизатора, противоположное верхнему отверстию, со скоростью, соответствующей скорости подачи расплава (4), таким образом, по существу, поддерживая уровень поверхности (10) в устойчивом положении. Для того чтобы уменьшить разбрызгивание и связанные с ним недостатки в ходе процесса пуска, изобретение предлагает устанавливать брызговик (16) на сопло (5), который предотвращает ударение брызг расплава (4), выходящего из выходов (9), о кристаллизатор, при этом брызговик (16) растворяется окружающим расплавом (4) по меньшей мере в устойчивом состоянии.A continuous casting method is described in which the melt (4) is supplied to the frame mold through the upper mold opening using a nozzle (5) having at least two opposite outlets (9), until the surface level (10) of the melt (4) ) does not reach a stable position above the outlets (9), and in which, in a stable state, at least the surface hardened casting (13) is removed through the bottom hole of the mold, opposite the top hole, at a speed corresponding to the feed rate Av (4), thereby substantially maintaining a surface level (10) in a stable position. In order to reduce spatter and related drawbacks during the start-up process, the invention proposes to install a splash guard (16) on the nozzle (5), which prevents the molten splash (4) coming out of the outlets (9) from impacting on the mold, while the splash guard (16) is dissolved in the surrounding melt (4) at least in a stable state.
