[0002] Electric kilns are equipment made of refractory materials for firing products. Their main feature is that they use electricity as a heat source and convert it into heat through electric heating elements. The outer wall of the electric kiln is made of metal, and inside it are refractory bricks and refractory asbestos. Electric kilns generally have an oxidizing firing atmosphere and can be used for bisque firing of (ceramic) works and firing of medium and low temperature glazes, as well as baking overglaze colors. Electric kilns are generally fired under computer control throughout the process, and different firing temperatures and curves can be set according to needs. The operation is convenient and safe. Simply put, electric kilns are used to print exquisite patterns on ceramics. The characteristics of electric kilns are: high thermal efficiency, precise temperature control, no need for combustion chambers, pipes, chimneys or smoke exhaust fans, fuel and slag piles, fast cooling, simple operation, and easy cleaning.
