摘要： A multi-strand process is provided for casting molten materials into ingots of desired shape. The process uses two inductors for receiving the molten material and applying the first and second electromagnetic force fields to form the molten material into the ingots. The inductors are located adjacent each other so that the first and second force fields interact with each other. A first device is associated with one of the inductors for applying a first alternating current at a first desired frequency to an associated inductor to generate the first magnetic force field. A second device is associated with the other of the inductors for applying a second alternating current at a second desired frequency to generate the second magnetic force field. The second frequency is set to a desired value in relation to the first frequency in order to control the first and second resulting containment currents circulating in the molten material. The containment currents are due to the first and second force fields and their interaction with each other. The containment currents each have a frequency above a lower established limit so as to prevent formation of substantial melt stirring and containment instabilities in either of the first or second inductors.

摘要： A process and apparatus for determining the value of parameters which affect emissivity of radiation from a metal load in an electromagnetic casting system. Infrared radiation being emitted from the surface of the load is sensed by an array of fiber optic filaments secured within elements of the electromagnetic casting system. Radiation signals are transmitted by the filaments to a signal processor which enables readout display of electromagnetic casting parameters such as liquid temperature, maximum load temperature, position of the liquid/solid interface, and head position.

摘要： An apparatus and process for operating a rolling mill having at least two rolls rotating at different speeds to produce a continuous strip material having a substantially constant final thickness comprises a mechanism for controlling the magnitude of the compressive force between the rolls in response to the ratio of the incoming strip speed to the outgoing strip speed. A mechanism is provided for comparing the ratio of the strip speeds to a ratio of the roll speeds and for adjusting the compressive force magnitude until the two speed ratios are substantially equal. In this manner, the amount of off-stage strip material produced during mill start-up is reduced and process stability and gage control during steady state operation is enhanced.
