LEVITATION MELTING METHOD USING AN ANNULAR ELEMENT
Publication/Patent Number: WO2020016062A1 Publication Date: 2020-01-23 Application Number: 2019068431 Filing Date: 2019-07-09 Inventor: Franz, Henrik   Spitans, Sergejs   Sehring, Björn   Assignee: Ald Vacuum Technologies GmbH   IPC: H05B6/44 Abstract: The invention relates to a levitation melting method and a device for producing cast bodies using an annular element made of a conductive material for introducing the casting of a molten batch into a casting mold. In the method, the annular element is introduced into the region of the electromagnetic alternating field between the induction coils in order to cast the molten batch, and the molten metal thus drains into the casting mold in a controlled manner by influencing the induced magnetic field.

LEVITATION MELTING METHOD USING MOVABLE INDUCTION UNITS
Publication/Patent Number: WO2020016061A1 Publication Date: 2020-01-23 Application Number: 2019068430 Filing Date: 2019-07-09 Inventor: Franz, Henrik   Bauer, Egon   Krieger, Andreas   Spitans, Sergejs   Sehring, Björn   Assignee: Ald Vacuum Technologies GmbH   IPC: H05B6/26 Abstract: The invention relates to a levitation melting method and to a device for producing cast bodies using movable induction units. In the method, induction units are used in which the respective opposing ferrite poles are designed to be movable together with the induction coils and can move in opposite directions. Thus, the induction units are arranged closely together in order to melt the batches so as to achieve an increased efficiency of the induced magnetic field. Upon casting the molten batch, the induced magnetic field is reduced by increasing the distance of the ferrite poles together with the induction coils, thus preventing the molten metal from coming into contact with the ferrite poles or the induction coils.

DEVICE AND METHOD FOR LEVITATION MELTING USING INDUCTION UNITS WHICH ARE ARRANGED IN A TILTED MANNER
Publication/Patent Number: WO2020016063A1 Publication Date: 2020-01-23 Application Number: 2019068432 Filing Date: 2019-07-09 Inventor: Franz, Henrik   Holz, Markus   Krieger, Andreas   Spitans, Sergejs   Sehring, Björn   Assignee: Ald Vacuum Technologies GmbH   IPC: H05B6/44 Abstract: The invention relates to a levitation melting method and to a device for producing cast bodies using induction units which are arranged in a tilted manner. In the method, induction units are used in which the respective opposing ferrite poles are not designed to lie on one plane with the induction coils but rather are tilted at a specified angle relative to the levitation plane. Thus, the efficiency of the induced magnetic field for melting the batches can be increased with the induction units. By virtue of the tilted assembly, the component of the induced magnetic field which effectively accounts for the holding force of the field for levitating the molten metal is increased.

Vorrichtung und Verfahren zum Schwebeschmelzen mit gekippt angeordneten Induktionseinheiten
Publication/Patent Number: DE102018117304A1 Publication Date: 2020-01-23 Application Number: 102018117304 Filing Date: 2018-07-17 Inventor: Franz, Henrik   Holz, Markus   Krieger, Andreas   Spitans, Sergejs   Sehring, Björn   Assignee: Ald Vacuum Technologies GmbH   IPC: H05B6/32 Abstract: Die Erfindung betrifft ein Schwebeschmelzverfahren und eine Vorrichtung zur Herstellung von Gusskörpern mit gekippt angeordneten Induktionseinheiten. Bei dem Verfahren werden Induktionseinheiten eingesetzt, bei denen die jeweils gegenüberliegenden Ferritpole mit den Induktionsspulen nicht in einer Ebene liegend ausgestaltet sind, sondern in einem bestimmten Winkel gekippt zur Levitationsebene. So kann bei den Induktionseinheiten eine Effizienzsteigerung des induzierten Magnetfelds zum Aufschmelzen der Chargen erzielt werden. Durch die gekippte Anordnung wird der Anteil des induzierten Magnetfelds, der effektiv zur Haltekraft des Felds für die Levitation der Schmelze beiträgt, vergrößert.
