Abstract
Beim Vergießen flüssiger Metalle stellt sich in moder nen Verfahren die Aufgabe, den Spalt zwischen ruhenden und bewegten Systemen abzudichten, damit keine Schmel ze über den Spalt ausfließt. When pouring liquid metals turns into moder NEN procedure the task of bridging the gap between resting and moving systems to seal, so that no melt ze flows out through the gap.
Bei Schmelzen mit hohen Temperaturen und der Nei gung, Legierungen zu bilden, fehlt es an Materialien, mit deren Hilfe die Schlitze dauerhaft abgedichtet werden kön nen. When melting with high temperatures and Nei to form alloys, there is a lack of materials with whose help the slots can be sealed permanently nen.
Durch den kombinierten Einsatz pneumatischer und elektromagnetischer Kräfte läßt sich ein Spalt besonders vorteilhaft abdichten, wenn die elektromagnetischen Kräfte dazu benutzt werden, den Flüssigkeitsdruck zu homoge nisieren, d.h. den Oberflächendruck auf einen konstanten Wert abzusenken. Der abgesenkte Druck kann pneumatisch kompensiert werden. Nach dem erfindungsgemäßen Ver fahren wird ein den minimalen Flüssigkeitsdruck am Spalt querschnitt nicht überschreitender Teil des Flüssigkeits druckes pneumatisch (3) und der Rest des Flüssigkeitsdruk kes durch elektromagnetische Kräfte (6, 14) kompensiert. Die elektromagnetischen Kräfte resultieren aus der Wech selwirkung einer magnetischen Induktion (6) mit Strömen in der Flüssigkeit (14). Through the combined use of pneumatic and A gap is particularly sensitive to electromagnetic forces seal advantageously when the electromagnetic forces be used to homogenize the fluid pressure nize, i.e. the surface pressure to a constant Lower value. The reduced pressure can be pneumatic be compensated. According to the Ver will drive the minimum fluid pressure at the gap cross-section not exceeding part of the liquid pneumatic pressure (3) and the rest of the liquid pressure kes compensated by electromagnetic forces (6, 14). The electromagnetic forces result from the change interaction of a magnetic induction (6) with currents in the liquid (14).
