（ホ）作用
二珪化モリブデンヒーターはヒーター表面温度が１３０
０℃程度で軟質化し脆さがなくなるのを利用し、その温
度以上で炉を傾動させる。(E) Function The molybdenum disilicide heater has a heater surface temperature of 130°C.
Taking advantage of the fact that the material becomes soft and less brittle at about 0°C, the furnace is tilted above that temperature.

になる。When the molybdenum disilicide heater (3) of the electric furnace (F) configured as described above is energized and the temperature inside the furnace reaches the melting temperature, glass raw materials are put into the crucible (9) and melted after a certain period of time. Then, it becomes molten glass. The temperature inside the furnace is maintained at 1300℃ or above, the gas burner (7) is ignited to heat the gutter (11), the molten metal is kept from solidifying in the runners, the two hydraulic cylinders (8) are operated, and the electric By tilting the furnace (F), the molten metal inside can be automatically taken out of the furnace through the gutter (11). At this time, the molybdenum disilicide heater (3) is softened, so it bends vertically near the bottom of the terminal.
When the electric furnace (F) is returned to its original vertical position, it becomes straight again.
