立形ルツボ溶融炉。In a vertical crucible melting furnace, a cylindrical graphite heater formed into a spiral shape is held in a vertical direction, and a crucible inserted into a hollow part of the heater is heated to a predetermined temperature by energizing the heater. In the above-mentioned cylindrical graphite heater, two cylindrical graphite heaters are arranged vertically so as to be coaxial with each other, while the heater located on the lower side has its lower end supported from below, and is also located on the upper side. The heater has a step formed at its upper end and is suspended by a holder that engages with the step, and the energizing terminals of the lower heater and the upper heater are made independent of each other, and each is connected to a heating power source. A vertical crucible melting furnace characterized by being connected to.
