Description
Technical Field

[0002] Alumina ceramic is a ceramic product made from alumina as the main raw material through processes such as high-temperature sintering and forming. It has characteristics such as high hardness, high wear resistance, excellent insulation performance, high heat stability, and good chemical stability, and is widely used in fields such as electronics, metallurgy, chemical engineering, and environmental protection.
[0003] Before the sintering and forming of alumina ceramic products, auxiliary drying is often required to remove the moisture remaining in the ceramic body to prevent sintering bubbles and ceramic cracking. The drying before the sintering and forming of alumina ceramic products generally requires a preheating process with gradually increasing temperature. Usually, the initial temperature should not be too high, generally 50 - 60 °C, to avoid surface cracking and cracking of the products. After the auxiliary drying is completed, the temperature in the oven needs to be gradually decreased to prevent damage to the ceramic products caused by rapid temperature changes. However, in the current drying technology before the sintering and forming of alumina ceramics, there is no relevant technology that can gradually increase the temperature and gradually decrease the temperature in the oven after the auxiliary drying is completed to ensure slow and uniform heating and uniform cooling.

During specific operation, when drying operation is carried out, the first heat dissipation groove 41, the second heat dissipation groove 42, and the first heat dissipation groove 41 are sealed by the blocking unit 44 to prevent heat loss from affecting the drying efficiency. After the drying is completed, the first heat dissipation groove 41, the second heat dissipation groove 42, and the first heat dissipation groove 41 are opened by the blocking unit 44 to achieve the effect of temperature reduction.
