The invention relates to a remelting plant comprising a furnace chamber (), which can be positioned over a crucible () of a melting station, an electrode rod (), which by way of a lead-through () can be inserted or is inserted in the furnace chamber (), in order to contact a consumable electrode (), and a guide column (), on which an electrode rod carriage () that is fixed-ly connected to the electrode rod () is guided in an axially movable manner, in order to move the electrode rod () in relation to the furnace chamber (), and on which a chamber carriage (), which is connected or can be connected to the furnace chamber (), is guided in an axially movable manner, in order to move the furnace chamber (). The guide column () is articulatedly connected at a first end to a rotary column () such that the guide column () can be inclined in re-lation to the rotary column () and can be rotated together with the rotary column () about the axis of rotation () of the rotary column (). The guide column () has in the region of the first end a weighing device (), which is preferably attached to the rotary column ().

Remelting plant and method for operating a remelting plant

A melting vessel for performing an electro-slag melting method and such a method are presented. Measuring devices measuring a temperature at different heights allow conclusions about position and height of a slag zone in the melting vessel during the method.

Electroslag remelting process and melting vessel

A method and a device for remelting metal in an electric furnace includes forming a slag bath to form molten material electrodes. The molten metal of the material electrodes solidifies in block form in a crucible apparatus as a result of cooling in such a way that a block growth forms from a block base using a progressing solidification process, wherein the block base is heated by applying energy directly to the block base to influence the cooling process.

Method and device for remelting metal in an electric furnace

In an electroslag remelting point with a mold ( ) for forming an ingot from the remelted material of at least one consumable electrode ( ), with a body ( ) having at least one vertically driven electrode rod ( ) for advancing a respective consumable electrode ( ), and with a hood ( ) which is disposed above the mold ( ) and has at least one opening ( ) which is concentric with the respective electrode axis (A), a pot-shaped boiler ( ) is provided which accommodates the mould ( ) and can be joined to the hood ( ) to form a chamber ( ) which is closed all round, completely encompasses the mould ( ) and can be connected via pipelines ( ) to a vacuum pump and/or a gas source, so that the chamber ( ) can be evacuated or filled with an inert gas.
