[0002] A porcelain sintering furnace, also known as a dental furnace or zirconia sintering furnace, is a high-temperature furnace specifically designed for the fabrication and restoration of dental prostheses. It is primarily used to sinter and melt dental materials such as porcelain powder, ceramics, and alloys to create prostheses that fit the patient's oral cavity. These materials, after being treated at high temperatures in the furnace, achieve excellent strength and aesthetics, making them suitable for prosthetic restorations. The furnace's tray is equipped with a shelf to hold the prostheses.

[0003] The installation between the placement frame and the tray is achieved by fastening the placement frame to the tray with bolts. This installation method requires disassembly and assembly tools, which is quite troublesome.
