Document Type and Number:
Japanese Patent JP2832539
Kind Code:
B2
Abstract:
The invention relates to a thermal treatment installation for molten metal having a metallurgical vessel for receiving the molten metal and a direct-current arc heating device, which is separate or operates as an integrated component and has at least one electrode arranged above the molten metal and at least one counter-electrode in contact with the molten metal. In order to provide a maintenance-free, easily exchangeable installation which permits an automatic, reliable connection of the counter-electrode to the current lead to the energy source, it is proposed that at least one element (30) for transferring the electrical energy to the counter-electrode (22) is provided on the outer casing (11) of the metallurgical vessel (10), and has a surface (31) which supports itself during the heating operation on a surface (41) of a counter-element (40) which is in connection with the electrical energy source (20) and can be positioned by mechanical means (45).
