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.
摘要翻译：提供了一种将熔融材料铸成所需形状的锭料的多股加工方法。该方法使用两个电感器来接收熔融材料并施加第一和第二电磁场以将熔融材料形成到锭中。电感器彼此相邻地定位，使得第一和第二力场彼此相互作用。第一装置与用于将第一所需频率的第一交流电应用于相关联的电感器的一个电感器相关联，以产生第一磁力场。第二装置与用于以第二所需频率施加第二交流电的另一个电感器相关联，以产生第二磁力场。相对于第一频率将第二频率设定为期望值，以便控制在熔融材料中循环的第一和第二产生的容纳电流。容纳电流是由于第一和第二力场以及它们彼此的相互作用。容纳电流各自具有高于较低建立极限的频率，以便防止在第一或第二电感器中的任一个中形成实质的熔融搅拌和容纳不稳定性。

摘要： A multi-strand apparatus and process is provided for casting molten materials into ingots of desired shape. The apparatus comprises a plurality of devices for receiving and electromagnetically forming the molten material into desired shape. Each of the receiving and forming devices includes an inductor for applying a magnetic force field to the molten material. The inductor in operation is spaced from the molten material by a gap extending from the surface of the molten material to the opposing surface of the inductor. An alternating current applying device sends current to its associated inductor to generate the magnetic force field. Circuitry associated with each of the inductors senses variations in their respective gaps. The improvement comprises a pulse width modulating circuit associated with said gap variation sensing circuitry being connected to the alternating current applying device for controlling the application of alternating current to the inductor. A device is connected to the pulse width modulating circuit for synchronizing turn-on of all of the current applying devices whereby beat frequencies due to interaction between the plurality of inductors are substantially eliminated.
