发明名称 METHOD AND DEVICE FOR CONTROLLING SPEED OF DRIVE OF ELECTRODE IN CONSUMABLE ELECTRODE FURNACE
摘要 <p>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 or ingot, such as changes in weight, as the melt proceeds. The base speed also takes into consideration the known geometry of the electrode, the furnace mold or crucible, the density of the ingot material, 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 and the top surface of the ingot.</p>
