Improved ERS and Envisat Precise Orbit Determination

An induction heating furnace includes a furnace body having a side wall extending so obliquely as to increase in radius from the bottom to the top edge portion and formed by a plurality of longitudinally split, conductive segments arrayed circumferentially and insulated from each other, a first induction heating coil arranged at an outer periphery of the side wall for subjecting a to-be-heated material accommodated in the furnace body to induction heating and a melt-use power source for supplying AC power to the first induction heating coil.
