Description

Technical Field

[0001] The utility model relates to the technical field of tube bottles, in particular to a gas annealing furnace. Background Art

[0002] The production process of tube bottles mainly includes: raw material pre-processing, batch material preparation, melting, molding and heat treatment. Among them, heat treatment is to eliminate or generate stress, phase separation or crystallization inside the glass, and change the structural state of the glass through processes such as annealing and quenching. When performing annealing treatment, an annealing furnace is required.

[0003] Existing annealing furnaces often use tunnel heating, using heat-resistant rails and hot spray guns to slowly anneal the tube bottles in batches in a straight line.

[0004] There are some problems. The return operation of the controlled bottles often takes about fifty minutes. If this annealing method is used, there may be a rapid loss of heat. The track of the heat-resistant guide rail is exposed to the high temperature environment for a long time, which reduces the working life. For this reason, we propose a gas annealing furnace.
