Description

Smart ceramic kiln capable of dynamic heat control from information on the position and surface area of ceramic The present invention relates to a smart ceramic kiln capable of dynamic heat control based on the position and surface area information of the ceramic. Conventional pottery kilns generally use a method of heating the entire interior of the kiln uniformly according to a "fixed heating curve (temperature rise profile)." However, since ceramic works differ in size, material, glaze characteristics, shape, and surface area, applying the same heating conditions results in the following problems. In particular, large ceramics may experience glaze bleeding or incomplete melting due to uneven heating, while small ceramics may experience problems such as excessive color change or pore formation due to excessive heat treatment. Additionally, because there are differences in radiant or convective heat depending on the position of the ceramics, the firing quality may deteriorate in some areas. Therefore, there is a need for research and development on smart ceramic kilns capable of dynamically adjusting the heating amount for each zone of the kiln based on ceramic surface area and location data.
