Abstract
In an induction furnace including a crucible having a crucible center axis and a coil member wound around the crucible, the coil member has a coil center axis oblique to the crucible center axis at an acute angle between 3.degree. and 10.degree.. The coil member is consequently wound around the crucible so that each winding of the coil member is inclined to the crucible center axis at an angle except 90.degree. and has a highest position and a lowest position on a crucible side wall of the crucible. An inlet port and an outlet port of the crucible are located at positions adjacent to the highest and the lowest positions of the windings, respectively.
