Description

technical field

[0001] The invention belongs to the technical field of flexible glass manufacturing, in particular to a muffle furnace silicon carbide heating system and a muffle furnace for manufacturing flexible glass. Background technique

[0002] The muffle furnace silicon carbide heating system is an important equipment for the hot end production line of flexible glass. It is used to heat and control the temperature of the molten glass after entering the muffle furnace. It is used as the heating device for the muffle furnace brick cavity and silicon carbide box. Furnace key equipment.

[0003] In the production process of flexible glass, the production of the hot end is continuous and uninterrupted. During the production process, the SiC heating system of the muffle furnace and the temperature of the SiC box are unreasonable, which is not conducive to the temperature control of the glass liquid and affects the chamber of the muffle furnace. Temperature regulation, whic...
