Embodiment Construction

[0032] figure 1 A crucible arrangement 10 , which is not shown in detail here, is shown as an electric furnace in the form of a stationary crucible system for use in the electroslag remelting method. such as especially image 3 As shown, the crucible arrangement 10 has a crucible container 11 of beaker-like design, which has a housing wall 12 and a crucible bottom 13 . The housing wall 12 is double-walled with a container inner wall 14 and a container outer wall 15 , between which a housing chamber 16 is formed for receiving a tempering medium, such as water or oil.

[0033] The crucible bottom 13 has a base plate 17 which is provided with a depression 18 in its middle. The heating device 20 is located below the bottom plate 17, and in image 3 Oriented coaxially to the central longitudinal axis 19 of the crucible container 11 in the heating arrangement shown in the figure, said heating device has a heating device 20 configured as a combustion device arranged on a transform...

Abstract

The invention relates to a method and a device for remelting metal in an electric furnace, wherein material electrodes are melted on by forming a slag bath, and the melted-on metal of the material electrodes solidifies in block form in a crucible apparatus (10) as a result of cooling in such a way that a block growth forms from a block base by means of a progressing solidification process, wherein the block base is heated to influence the cooling process, wherein the block base is heated by applying energy directly to the block base.

Description

technical field [0001] The invention relates to a method for remelting metals in an electric furnace, in which a material electrode is melted by forming a slag pool, and the molten metal of the material electrode solidifies in a crucible device as a result of cooling. The ingot shape is such that an ingot growth is formed from the ingot base by a preceding solidification process, the ingot base being heated to influence the cooling process. Furthermore, the invention relates to a device for heating the base of an ingot when remelting metal in an electric furnace. Background technique [0002] In the electroslag remelting method, material electrodes are remelted in order to produce material ingots, wherein the material ingots serve as semi-finished products for the production of components of high raw material quality, e.g. for use in power plants which must ensure the highest Forgings for component reliability. In view of the systems and methods used here, a distinction is...
