[0002] The cement kiln preheater is a raw material preheating device in a cement production line, and the preheater is provided with a hanging piece. In the service process, the hanging piece needs to withstand high temperature, corrosion and abrasion, so the material of the hanging piece needs to be high; compared with the heat-resistant alloy steel hanging piece, the ceramic hanging piece has a longer service life, higher safety and stability and lower weight, and is more advantageous in the service scene; the existing ceramic hanging piece is mostly made of reaction sintered silicon carbide material by extrusion molding. This molding method is beneficial to the production of straight cylinder and thin-walled products. These characteristics cause the reaction sintered silicon carbide hanging piece to be easily broken in the cement kiln preheater, and long-term safe production cannot be guaranteed.
