摘要： A process and a device for regulating the position of the tip of an electrode immersed in an electric furnace heated by electric arc or resistance heating. To precisely measure the position of the electrode tip and to position it in operation, a series of gas containers are introduced into the electrode in succession at certain intervals, with each gas container being given a serial number (n.sub.i). The position of the electrode tip is determined by computer from the data of the last gas container with the serial number (n.sub.j) and the current number of the melted-open gas container, determined by gas analysis, using the gas that rises in the furnace through the melting process. Control technology is then applied to the drive of the electrode bearing device.

摘要： There is disclosed an arc reactor for treating a material in powder form conductive at very high temperatures, the reactor comprising a vertical electrically insulated sleeve cylindrical in shape, an upper electrode coaxially mounted with the sleeve at its upper end, a bottom electrode cooperating with the upper electrode, injectors for injecting a gas tangentially into the sleeve in order to create a vortex inside the same, a feed mechanism for introducing the powder material inside the sleeve near its upper end, so as to form a uniform cylindrical curtain of particles falling down into the sleeve, the particles being centrifugally projected against the internal wall of the sleeve by the vortex and entirely covering the internal wall while they are being simultaneously treated by the arc column, a crucible positioned under the sleeve to collect the treated particles in molten form that drip down from the sleeve, the molten material in use being in conductive contact with the bottom electrode, and a drive system to adjust a vertical position of the upper electrode, the upper electrode being slideable through the upper end and being made of a consumable electrode material. The upper electrode does not require water cooling and lasts for longer operation.

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.

摘要： A plurality of measuring conductors leading from the bottom of a multi-phase electric furnace and symmetrically disposed with respect to one another and with respect to said furnace, and each connected to an associated impedance, each of said impedances having a common junction. In this fashion, cancellation of induced voltages in the measuring conductors is effected, thereby enabling generation of a potential at the common junction of the aforementioned impedances accurately representative of the potential at the bottom of the furnace. Volt meters connected from this common junction to the electrodes in the furnace can then give an accurate reading of the crater voltages.
