摘要： An electrode joining apparatus for joining a free electrode to a fixed electrode. The electrode joining apparatus includes an electrode holder configured to selectively hold the fixed electrode and a torque device positioned above the electrode holder, the torque device configured to grip and spin the free electrode to join the electrodes. The electrode joining apparatus can include an axial passage defined through the electrode holder and the torque device. A retractable spacer can be movably connected to the electrode joining apparatus, the retractable spacer configured to selectively move into the axial passage. The retractable spacer can be used to form a gap between the free electrode and the fixed electrode before the joining process is initiated. Electrode joining apparatus can also include a spacer drive mechanism coupled to the retractable spacer, the spacer drive mechanism configured to selectively move the retractable spacer into the axial passage.

摘要： An electrode column and a method of determining the length of the electrode in it in an active furnace. The column is a Söderberg column including a mantel in which the electrode is movable in an axial direction by lower and upper slipping clamps which are movable relatively to each other by slipping cylinders. The method includes the steps of moving, with the slip clamps, the electrode in a downslip relatively to the mantel with the slipping cylinders and gravity and measuring the force required to move the electrode with only the upper slipping clamp against predetermined reaction forces acting against movement of the electrode and computing these parameters to determine the mass and so the length of the electrode relatively to the theoretical mass of the undamaged electrode at the time of movement.

摘要： A method of and apparatus for controlling an electroslag remelting furnace by driving the electrode at a nominal speed based upon melting rate and geometry while making minor proportional adjustments based on a measured metric of the electrode immersion depth. Electrode drive speed is increased if a measured metric of electrode immersion depth differs from a set point by a predetermined amount, indicating that the tip is too close to the surface of a slag pool. Impedance spikes are monitored to adjust the set point for the metric of electrode immersion depth based upon one or more properties of the impedance spikes.

摘要： The present invention relates to a method for determination of the electrode tip position for consumable electrodes in electric smelting furnaces, which electrodes being submerged in the furnace charge. The voltage between two geometrically displaced points on the outside of the steel wall of the furnace pot is measured during operation of the furnace, points being situated as close as possible to the electrode for which the electrode tip position is to be determined, and as far away as possible from the other electrodes in the furnace. The electrode current for the electrode for which the electrode tip position is to be determined, is recorded at the same time as the voltage between the two points are measured, whereafter the difference between measured voltage between the two points and measured electrode current is calculated, and where the absolute value of difference increases when the electrode tip position increases and decreases when the absolute value of difference decreases.

摘要： A compensation device for the influence of the weight of a power feed line on a weight measurement device determining the weight of an electrode and/or the melting rate in an electro-slag remelting process, in a vacuum arc furnace or the like. When an x-y device is adjusted, a weight jump occurs due to the forces of the power cable or the forces of the bellows, which has a disturbing effect on the rate definition. This weight jump can be prevented by means of mechanical devices, or can be made so small that it no longer constitutes a disturbance. However, the expenditure for this is disproportionately high. The invention is more cost efficient, since hardware or software means suffice. The weight function G=f(t) is extrapolated and compared with the actually measured weight G'=f(t). The magnitude of the difference between the two is stored and later added as a correction value.
摘要翻译：在真空电弧炉等中，用于影响供电线的重量对确定电极重量的重量测量装置和/或电渣重熔过程中的熔化速率的影响的补偿装置。当x-y装置被调整时，由于电力电缆的力或波纹管的力而产生重量跳跃，这对速率定义具有不利影响。这种重量跳跃可以通过机械装置来防止，或者可以使其小到不再构成干扰。但是，这方面的支出却不成比例。本发明更具成本效益，因为硬件或软件装置就足够了。权重函数G = f（t）被外推，并与实际测量的权重G'= f（t）进行比较。两者之间的差值的大小被存储并且随后被添加为校正值。

摘要： An electric arc furnace control system is provided for positioning the furnace electrodes in accordance with the resistance of the arc. This is accomplished by balancing the arc current signal against a voltage signal multiplied by a signal representing the arc circuit power factor to provide an error signal. An analog command signal is then derived from the error signal to control the direction and speed of the electrode hoist drive motor.
