    • A method is proposed for the solidification of a non-metal melt (130) which is located in a crucible (120) arranged in the device (100), wherein the device (100) has a multiplicity of inductors (100) for the creation of magnetic fields. By feeding in a first set of phase-displaced alternating currents (I1a, I2b, I3c, I4d) having a first frequency (f1), a first travelling field (W1) is created in the melt (130). By feeding in at least one second set of phase-displaced alternating currents (I2a, I2b, I3c, I4d) having a second frequency (f2), a second travelling field (W2) is created in the melt (130) which is directed against the first travelling field (W1), wherein the inductors (100) are arranged on the crucible (120) in a vertically extending arrangement, so that the alternating fields created (W1, W2) pass through the melt (130) in vertical direction (Y) and have a flow force minimum on the crucible or vessel wall.
    • 提出了一种用于凝固位于装置(100)中的坩埚(120)中的非金属熔体(130)的方法,其中装置(100)具有多个用于产生的电感器(100) 的磁场。 通过馈送具有第一频率(f1)的第一组相移的交流电流(I1a,I2b,I3c,I4d),在熔体(130)中产生第一行进场(W1)。 通过馈送具有第二频率(f2)的至少一组第二组相移的交流电流(I2a,I2b,I3c,I4d),在熔体(130)中产生第二行进区(W2),第二行 所述第一行进区域(W1),其中所述电感器(100)以垂直延伸的布置布置在所述坩埚(120)上,使得产生的交变场(W1,W2)在垂直方向上穿过所述熔体(130) Y)并且在坩埚或容器壁上具有最小的流动力。
