    • An electrode for a smelting furnace comprises an elongate casing including a plurality of spaced, inwardly projecting ribs extending radially from an inner surface of the casing towards the centre of the casing. A central core of a pre-baked electrode, typically a solid or hollow pre-baked graphite electrode, is disposed within the casing free of the projecting ribs and defines a space between the core and the inner surface of the casing. A heating zone is located intermediate the ends of the casing so that a carbonaceous electrode paste received or receivable within the space between the core and the inner surface of the casing is calcined into a baked, hard form upon entering the heating zone. The projecting ribs assist in baking the electrode paste and in anchoring or supporting the electrode to reduce the risk of nipple or joint fracture of adjacent pre-baked electrodes. The electrodes are particularly useful in the smelting of ferrochromium and in the reduction of ores such as ilmenite. They also have application in the smelting of scrap metal in steel furnaces.
    • 用于冶炼炉的电极包括细长壳体,其包括从壳体的内表面径向延伸到壳体中心的多个间隔开的向内突出的肋。 预制电极的中心芯,通常为固体或中空预焙石墨电极,设置在壳体内而不具有凸肋,并且在芯体和壳体的内表面之间形成空间。 加热区域位于壳体的端部之间,使得在进入加热区域之后,在芯部和壳体的内表面之间的空间内容纳或接收的碳质电极浆料被煅烧成烘烤的硬质形式。 突出的肋有助于烘烤电极浆料并且锚固或支撑电极以减少相邻预烘烤电极的乳头或关节破裂的风险。 电极特别适用于冶炼铬铁和还原矿石如钛铁矿。 它们也适用于炼钢炉中废金属的冶炼。

    • The invention relates to a method and an arrangement for measurement of electrode paste in an electrode column of an electric arc furnace. The electrode column (10) comprises a steel casing (11) surrounding the electrode paste and said electrode column (10) is provided with a contact shoe ring (12) to conduct electric current to the electrode. The electrode column (10) is filled with electrode paste by introducing said paste from above into the steel casing (11). The electrode paste evolves through different phases, from raw paste in the upper part of the steel casing (11) to melted paste and further to baked paste (18) in the lower part of the electrode column (10). In the invention a plurality of laser devices is provided on the top of the electrode column (10). The level of the raw paste (16) corresponding to the height of the paste cylinder in the steel casing (11) is determined with the laser beam transmitted by a first laser device. The level of the molten paste (17) in the steel casing (11)is determined with the laser beam transmitted by a second laser device. The data received from the laser devices is used for calculation of the distances of the levels of the raw paste (16) and molten paste (17) from the contact shoe ring(12).

    • In exactly the same manner as larger furnaces, electric reducing furnaces which can be used for test purposes during ferroalloy and nonferrous processes and in a simplified design as industrial submerged arc furnaces require complete engineering, and in this context the engineering costs turn out to be disproportionate since, instead of decreasing with the furnace size, they largely represent a type of fixed cost. Modifications to existing furnaces, be they large or small, are also very costly and complicated. Furnaces that have already been erected can be mechanically adapted and/or modified only with great difficulty. In order to develop a smaller, flexible reducing furnace which makes it possible to provide reducing furnaces which are inexpensive to design and nevertheless can be adapted in a process-specific manner for test operation and/or in a simplified design for corresponding industrial use, the invention proposes designing the electric reducing furnace (1) without a welded steel structure and from modules which can be exchanged as desired, in such a way that it can be completely disassembled, and proposes using individual modules and/or a plurality of modules having different dimensions and materials to make it possible to individually vary the dimensions and the structure of the electric reducing furnace (1) in terms of the furnace vessel (2), the side walls (3), the base (4), the cover (5) and the arrangement of the electrodes (6).
