Description

Technical Field

[0001] The present invention relates to the technical field of high-temperature metallurgical equipment, in particular to a baking furnace and a baking method for zircon and soda ash. Background Art

[0002] Zircon is a natural mineral used in refractory materials (called zirconate fire bricks, such as zirconium corundum bricks), casting sand (precision sand for precision castings), ceramics and enamelware. It is also used in metals (sponge zirconium), alloys, glass and compounds (zirconium dioxide, zirconium oxychloride, sodium zirconate, potassium fluozirconate, zirconium sulfate, etc.).

[0003] During the zircon processing process, a baking furnace is required to heat the zircon. However, when the zircon and soda ash are roasted and heated for reaction, in order to prevent heat loss and the escape of gaseous substances produced by decomposition into the air, thereby reducing the amount of alkali participating in the reaction and affecting the reaction efficiency, the furnace needs to be sealed during baking. However, during sealing, the large amount of CO2 produced by the reaction of zircon and soda ash can easily lead to excessive pressure in the furnace, causing damage to the furnace body. At the same time, the sodium silicate produced by the reaction is in a molten state at high temperature and easily adheres to the refractory material of the furnace wall to form rings or crusts, which hinder material flow and heat transfer. Therefore, existing baking furnaces are not suitable for the roasting reaction operation of zircon and soda ash. Summary of the Invention
