Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to float glass kiln technical field relates to a kind of melting furnace pressure measuring devices. BACKGROUND
[0002] The glass melting furnace pressure is a crucial process parameter in the glass production process, which directly affects the melting and refining effect of glass liquid, and further affects the quality of final glass product. Therefore, accurate and reliable detection and control of the kiln pressure are of great significance to glass production.
[0003] The kiln pressure, as an important process parameter of the glass melting furnace, directly affects the safety, efficiency and product quality of glass production. Too high or too low kiln pressure will adversely affect the glass melting process.
[0004] Too high kiln pressure will increase the erosion of the refractory material of the melting furnace, reducing the service life of the melting furnace. At the same time, too high kiln pressure will also affect the refining of glass liquid, causing heat loss outside the melting furnace, resulting in a decrease in melting furnace temperature and an increase in energy consumption.
[0005] Too low kiln pressure will increase the surface viscosity of glass liquid, making it difficult to remove bubbles during the melting process, which is not conducive to melting and refining, resulting in an increase in bubble defects. In addition, too low kiln pressure will also allow cold air to enter the kiln, causing the melting furnace temperature to decrease and energy consumption to increase. INVENTION CONTENTS
