[0002] Annealing is a metal heat treatment process, which means slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate rate. In a broad sense, annealing is a heat treatment process for materials, including metal materials and non-metallic materials. The purpose of annealing new materials is also different from that of traditional metal annealing. Annealing can soften materials and improve mechanical properties, increase the toughness of materials, and stabilize the organizational structure.

[0003] When a traditional annealing device is annealing, due to the differences in size and shape of the objects inside, uneven heating may easily cause certain deformation of the material, affecting its appearance and even its performance. At the same time, after heating, the overall temperature is high, making it difficult to take out, and it is easy to get burned if the operation is wrong. In order to solve the above problems, an annealing device for zirconia ceramic blanks is urgently needed to solve the above problems. Utility Model Content
