摘要： A method and apparatus for controlling electrode drive speed in a consumable electrode furnace. The electrode drive speed is regulated at a base speed computed from measured changes in physical characteristics of the electrode (18) or ingot (34), such as changes in weight, as the melt proceeds. The base speed also takes into consideration the known geometry of the electrode (18), the furnace mould or crucible (12), the density of the ingot material (34), and the speed of movement of the bottom of the ingot if any. This base speed is increased or decreased by a trim speed determined from measurement of an electrical phenomenon associated with the consumable electrode process, which electrical phenomenon has a relatively long term value related to the distance between the bottom surface of the electrode (18) and the top surface of the ingot (34).

摘要： An ohmic heater for heating a conductive fluid has a plurality of electrodes mounted to a structure with spaces between the electrodes. The electrodes (14) are selectively connect to poles (38, 40) of a power supply, so that some electrodes are connected to the poles and others remain isolated from the poles. Shunting switches are provided for connecting two or more of the isolated electrodes to one another. The shunting switches allow formation of a large number of different connection schemes having a variety of different electrical conduction paths through fluid in the spaces and a variety of resistances between the poles with relatively few electrodes and spaces.

摘要： The invention relates to a method for electrical pre-drying of a moist blank made from a ceramic raw mixture, wherein the blank is connected to a power circuit and an alternating current is passed through the blank. In so doing, the alternating current is passed through the blank at a frequency higher than the mains frequency. Significantly less electrical power is required to achieve a uniform drying result.
