    Abstract: A bottom electrode for a metallurgical vessel operated with direct current, consisting of an outer part made of a first material arrangeable substantially outside a bottom of the vessel so as to face the vessel, and an inner part made of a second material and connected to the outer part so as to face an interior of the vessel. The inner part is configured to wear when in contact with molten metal in the vessel, and includes a metallic first structural part that consists substantially of a material comparable to the molten metal. The first structural part has an end adjacent the outer part with a cross-section adapted to that of the outer part. The first structural part is configured to prevent a flow of melted electrode material as well as the molten metal. The inner part further includes a high temperature resistant second structural part configured to compliment the first structural part, the first and second structural parts being coaxial to one another.

    Abstract: An inert gas flow is introduced into a molten metal bath at a location in a vessel. The absolute pressure of the gas flow through the molten metal other than zero flow is determined. The pressure acting on the surface of the bath is measured and the difference between the surface pressure and the absolute pressure is determined. The difference in converted into a distance measurement that reflects the actual distance between the surface of the bath and the location of introduction of the gas flow into the bath. The distance measurement is compared with a predetermined desired distance value and a resultant measurement is formed therefrom. The level of the bath is regulated as a function of the resultant measurement. The resultant measurement is converted into an electric setting signal and sent to a setting member for regulating the level of the bath and/or the amount flowing out of or withdrawn from the vessel.

    Abstract: A supporting arrangement for the transport belt in thin strip casting plants. The liquid steel is cast onto the circulating transport belt. On its underside, the transport belt has devices for generating a negative pressure and for supporting the belt as well as for cooling. In the past, rollers were used for supporting the belt. Between the supporting points of the belt on the rollers, upward curvatures of the belt may occur. This is avoided by the use of supports of which the spacings measured transversely to the transporting direction are greater than the lengths of the supports in this direction.

    Abstract: Metal strip close to its final dimensions is cast using a strip-casting apparatus provided with a melt-holding vessel and a conveyor belt, in which a metal melt, in particular steel, flows out of a casting nozzle of a closable pouring chamber which can be put under vacuum and is connected via a siphon to a main chamber which can be put under pressure. The casting nozzle is inclined by about 45.degree. and is of trumpet-like configuration in the region of the orifice on the inside of the nozzle wall remote from the main chamber. Additionally, a shut-off element which can be opened in a slit-shaped manner is provided near the orifice of the casting nozzle.

    Abstract: A metallurgical vessel (10) includes at least one metallic electrode (20) fastened thereto having a chamber within the vessel (10) for holding a melt (19) and having a bottom surface, a shell (14) abutting the bottom surface, and a flanged tube (31) arranged on the shell (14) with the flanged tube (31) having a flanged surface (32). The electrode (20) is disposed coaxially with respect to the flanged tube (31) and is formed by first and second bars (21, 22) connectable to one another. The first bar (21) has the top face positioned proximate to the bottom surface of the chamber and penetrates the vessel (10) for contact with the melt. The second bar (22) is positioned against the bottom face of the first bar (21) and extends out from the vessel (10), the first bar having a should region (23) positioned annularly thereabout adapted to contact and lean against the flanged surface (32) of the flanged tube (31). A coolant provision and discharge device provide coolant to the second bar (22) through a coolant feed line (51) and a discharge line (53) and a current feed device provides current to the electrode. A hold-down mechanism (33) attaches the current feed device, the coolant feed line (51) and the discharge line (53) to the flanged tube (31).

    Abstract: This invention relates to an electrode positioning mechanism of an electric, electric arc or reduction furnace, in particular for smelting steel, with a guide column, having a mast arm to hold the electrode and guided in a guide frame by front and lateral guide rollers, which are located in a nest, and which can be moved vertically, whereby there are mechanical damping elements to damp mechanical vibrations. To create an electrode positioning mechanism which uses simple means to achieve a vibrational isolation of the individual components of the electrode positioning mechanism, and which reduces the breakage of electrodes in comparison to the devices of the prior art which use complex damping means, the invention proposes that the damping elements 14 be located between the front and lateral guide rollers 6 and the guide frame 7.
