Tin bath flow gate baking furnace

Abstract

The invention relates to equipment for production of float glass and provides a tin bath flow gate baking furnace. According to the tin bath flow gate baking furnace, a furnace body shell is of a furnace steel structure (3); a furnace lining (8) is arranged on a bottom substrate of the furnace steel structure (3); an inner wall body (2) and a furnace partition wall (10) are paved on the upper part of the furnace lining (8); the inner wall body (2) is arranged at two sides of two ends of the furnace lining (8); the furnace partition wall (10) is arranged between the two inner wall bodies (2); the outer side of the periphery of the inner wall bodies (2) and the top of the baking furnace are provided with outer wall bodies (1); and a gate baking inner cavity and a combustion chamber (14) which are vertically arranged are formed in a cavity between the furnace partition wall (10) and the inner wall bodies (2). The quick heat impact of open fire flame on the gate is avoided, and the phenomenon that the gate is contacted with the high-temperature molten glass and is blasted or has too long bubble removal time because the preheating temperature is extremely low or the temperature difference of the upper and lower parts is high is avoided.

Description

technical field [0001] The invention relates to equipment for producing float glass, and mainly relates to a tin tank flow gate baking furnace. Background technique [0002] Float glass production technology is the most advanced flat glass production technology today. It is famous for its natural glass surface polishing quality, high output, and easy large-scale industrial automation production. The flow channel is the throat part of float forming, and generally needs to be equipped with a heat-resistant steel safety cut-off gate (manually controlled opening) and one or two ceramic quartz flow control gates (electrically controlled). The safety ram is used for the float glass leader and handling accidents. It is pulled to the side of the flow channel for standby during normal production, and the flow ram is an essential tool for adjusting and controlling the pulling amount and output of the float glass during normal production. The lifting adjustment Frequently, it is s...

AI Technical Summary

Problems solved by technology

In some factories, due to improper material selection or (and) improper preheating and baking operations, the problem of bursting and scrapping after contacting high-temperature glass liquid or excessively long defoaming time (over 24 hours) occurs from time to time.
