摘要： PROBLEM TO BE SOLVED: To solve problems that an amount of oxidation of heat resistant steel used in a kiln under an indirect heating is increased, the steel cannot be used due to the increase of thermal distortion at high temperature exceeding 1100 deg.C, and a large product cannot be manufactured by using ceramics. SOLUTION: A hard fireproof material is formed in a cylindrical steel plate provided with a charging wall and an exhaust wall at the front and rear parts thereof to have a furnace body. On both the walls, a plurality of through holes are opened at positions near the center so as not to come into contact with inner powder to be treated even upon rotation and a rod type silicon carbide heater is mounted. At the central part of the charging wall, a hole is opened and used as an inlet port. At the end of the exhaust wall, the side wall of the cylinder is extended and a hole is opened to be used as an exhaust port. On the outer surface of the furnace body, two tires and sprockets are provided and assembled with four support rollers and two stopper rollers and a rotating speed reducer similarly to a well-known rotary kiln.

摘要： PURPOSE:To improve the safety in the molten glass tapping operation by holding the above electric furnace at a temp. higher than the softening temp. of a molybdenum disilicide heater, and making the furnace tiltable. CONSTITUTION:A rack 4 is formed by a shape steel 29 and a steel sheet 1, and the electric furnace F is placed on the rack through a shaft 16 and a bearing 17 and made tiltable by a hydraulic cylinder 8. The molybdenum disilicide heater 3 of the furnace F is energized. When the furnace temp. reaches the melting temp., glass material is charged in a crucible 9 and melted. The furnace temp. is then held at a temp. higher than the melting temp. of 1300 deg.C of the heater 3, a trough 11 is heated by a burner 7, and then the furnace F is tilted by the cylinder 8. Since the brittleness of the heater 3 vanishes at >=1300 deg.C, the heater 3 is only bent when the furnace is tilted, and not damaged. Since the molten glass is automatically tapped by this method, manpower is not needed for the operation, and safety is improved.
