Abstract
PURPOSE:To observe distribution state of constitutional element in the arbitrary cross section in a crucible in real time, by attaching a coil forming a magnetic field for convection control into tilted magnetic field to a magnet applying the magnetic field for convection control arranged around a crucible. CONSTITUTION:A superconducting magnet 7 consisting of one couple of saddle- shaped coils 7A and 7A applying horizontal magnetic field Ho for convection control is counter-arranged in the symmetrical position to the axis of the cru cible 1 around the crucible 1 storing a melt compound 3 therein and simultane ously plural sheets of coils 8a-8n for gradually changing flux density of horizon tal magnetic field Ho applied from the magnet 7 in the vertical direction and forming a proper tilted magnetic field is attached.
