Description

Technical Field

[0002] A kiln or furnace is a furnace used to fire ceramics and sculptures or to fuse enamel to the surface of metal objects. It is usually made of bricks and stones. It can be made into various sizes according to needs and can be operated by combustible gas, oil or electricity. According to the type of calcined materials, it can be divided into: ceramic kiln, cement kiln, glass kiln, enamel kiln, lime kiln, etc.

[0003] The control of kiln temperature is crucial for ceramic firing. The temperature range that needs to be reached is usually between 800 degrees Celsius and 1400 degrees Celsius. Depending on the material of the object being fired and the desired firing effect, the required temperature in the furnace cavity is also different. For example, the firing temperature of porcelain is generally between 1250℃-1350℃, while the firing temperature of pottery is between 1000℃-1200℃. Traditional kilns generally have only one zone in the furnace cavity, and only one constant temperature in the kiln. Ceramic objects can only be fired at one temperature, which affects the applicability of the kiln and cannot achieve multi-temperature heating. In addition, traditional kilns can only fire a batch of ceramic objects at a time, and the processing efficiency is low. Summary of the invention
