Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal glass production, in particular to a molding furnace heater replacement tool. Background Art

[0002] In the overflow method of substrate glass production, the glass liquid flows downward along the two overflow surfaces of the overflow brick and finally meets at the bottom of the overflow brick to form substrate glass with high surface quality.

[0003] Since the viscosity of molten glass varies with temperature, a corresponding heater needs to be installed in the glass forming furnace area, and by adjusting the power of the heater, a corresponding temperature distribution field of the substrate glass is provided to obtain substrate glass that meets product quality.

[0004] Existing heaters are installed in designated positions before the glass production furnace is heated. After a period of use, the heaters may be damaged prematurely before their designed life due to some reasons within the heaters themselves or externally. At this time, in order to ensure the production process quality of the substrate glass, the damaged heaters need to be replaced. Since the operating environment temperature of the heaters is around 900°C, in such a high-temperature environment, there is a great risk of fire and burns when operators replace the heaters. At the same time, when replacing the heaters, part of the furnace cavity will be completely exposed to the air, which has a great impact on the temperature field in the furnace.
