[0002] In industrial production, especially in the chemical and metallurgical industries, equipment that can withstand ultra-high temperatures is often needed. As a widely used heat treatment equipment, the performance of the rotary kiln directly affects production efficiency and product quality. Traditional rotary kiln tubes are mostly made of metal materials, which cannot withstand ultra-high temperature environments for a long time and are prone to deformation at high temperatures, affecting service life and safety.

[0003] The rotary kilns in the existing technology are mostly made of metal furnace tubes. When the furnace tubes are long, the connection between the furnace tubes is mostly made by welding. The furnace tubes connected by welding cannot withstand ultra-high temperatures. Therefore, it is necessary to develop a furnace tube for an ultra-high temperature rotary kiln to solve the above technical problems. Utility Model Content
