Description

Technical Field

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

[0002] Zircon sand is a natural mineral used in refractory materials (such as zirconate firebricks, like zircon corundum bricks), sand for casting molds (precision sand for casting molds), ceramics and enamelware. In addition, it is also used in metals (sponge zircon), alloys, glass, and compounds (zirconium dioxide, zirconyl chloride, sodium zirconate, potassium fluorozirconate, zirconium sulfate, etc.).

[0003] During the processing of zircon sand, a baking furnace is required to heat the zircon sand. However, when roasting and heating zircon sand and soda ash, in order to prevent heat loss and the escape of gaseous substances generated by decomposition into the air, which reduces the amount of alkali participating in the reaction and affects the reaction efficiency, etc., it is necessary to seal during baking. However, a large amount of CO2 generated by the reaction of zircon sand and soda ash during sealing easily causes the pressure in the furnace to be too high, resulting in problems such as furnace body damage. At the same time, the sodium silicate generated by the reaction is in a molten state at high temperatures and is easily bonded to the refractory material on the furnace wall, forming a ring or crust, hindering the flow of materials and heat transfer. Therefore, the existing baking furnaces are not suitable for the roasting reaction operation of zircon sand and soda ash. Summary of the Invention
