摘要： In an arc furnace or melted furnace employing concentric graphite inner and outer electrodes (30, 20), the accumulations of tolerances, distortion and mechanical forces can cause a loss of concentricity leading to reduced performance and eventually to electrode degradation. To avoid that condition, a plurality of insulating spherical or cylindrical spacers (42, 44, 46, 48) are disposed in the annular gap (40) between the inner and outer electrodes (30, 20). The spacers (42, 44, 46, 48) are held in position by arcuate recesses (43, 45, 47, 49) in the outer surface of the inner electrode or in the inner surface of the outer electrode (20). The electrode may be constructed in segments (22, 24, 26 and 32, 34, 36) that are assembled by threading one segment into another segment.
摘要翻译：在使用同心石墨内外电极（30,20）的电弧炉或熔化炉中，公差，变形和机械力的积累可导致同心度的损失，导致性能降低并最终导致电极劣化。为了避免这种情况，在内外电极（30,20）之间的环形间隙（40）中设置多个绝缘球形或圆柱形间隔件（42,44,46,48）。间隔件（42,44,46,48）通过在内部电极的外表面或外部电极（20）的内表面中的弓形凹部（43,45,47,49）保持就位。电极可以被构造成段（22,24,26和32,34,36），其通过将一个段穿过另一个段来组装。

摘要： The present invention relates to a machine for three-dimensional measurement of graphite electrodes and a method for performing a very precise three-dimensional measurement of the huge cylindrical or nearly cylindrical parts that make up graphite electrodes, enabling calculations to be performed that allow optimal machining of said parts, which is to be performed after measuring, since they have imperfections on the surface thereof that cause the cylinders to not be perfect or have acceptable tolerances for the use of the electrode. After measuring, the electrode can be machined to give it a perfect, standardised cylindrical shape, necessary to be used as an electrode in electric arc furnaces, avoiding the minimum loss of material given the high economic cost thereof.

摘要： An electrode assembly is secured against loosening/unscrewing and cracking of carbon and/or graphite electrodes. The electrodes are connected in columns with threaded connection elements, i.e., carbon nipples. The nipples have at their equator 80 to 110% of the diameter of the electrodes. Although the electrodes are connected by the nipples, they are not in direct contact with each other. This joint design is a "hybrid" between the widespread conventional nipple joint design and the rarely used male/ female joint design. Further, the male/ female joint design geometrical design is improved by precluding end-face contact of the electrodes and thus all electrical current must pass through the fully engaged threads of the male and female surfaces and not through the end- faces of the electrodes.
摘要翻译：固定电极组件以抵抗碳和/或石墨电极的松动/松动和破裂。电极连接成具有螺纹连接元件的列，即碳芯。乳头在其赤道处具有电极直径的80至110％。虽然电极通过接头连接，但是它们不是彼此直接接触。这种联合设计是广泛的常规乳头关节设计和很少使用的男/女联合设计之间的“混合”。此外，通过排除电极的端面接触来改善阳/阴接头设计几何设计，因此所有电流必须通过阳表面和阴表面的完全接合的螺纹，而不是通过电极的端面。

摘要： Graphite electrodes for the production of aluminum by carbothermic reduction of alumina are either submerged in the molten bath in the low temperature compartment or they are horizontally arranged in the side walls of the high temperature compartment. The electrodes are manufactured by using a mixture of coke particles covering the complete particle size range between 25 pm to 3 mm and by using an intensive mixer to effectively wet all coke particles with pitch. The electrodes have a flexural strength of at least 20 N/ mm 2 . By using a complete range (continuum) of particle sizes in conjunction with an intensive mixer, the geometric packing of the particles is significantly improved, hence the material density is increased and thus a higher mechanical strength as well as improved electrical conductivity in comparison to conventional graphite electrodes is achieved.
摘要翻译：通过碳氧化还原氧化铝生产铝的石墨电极被浸没在低温隔室中的熔池中，或者水平地布置在高温隔室的侧壁中。电极通过使用覆盖25μm至3mm之间的完整粒度范围的焦炭颗粒的混合物并通过使用强化混合器来有效地润湿所有具有沥青的焦炭颗粒来制造。电极的弯曲强度至少为20N / mm 2。通过与浓缩混合器结合使用粒度的完整范围（连续体），颗粒的几何填料显着提高，因此与常规的相比，材料密度增加，因此具有更高的机械强度以及改善的导电性实现石墨电极。
