[0002] A rotary kiln is a thermal equipment for calcining, roasting or drying granular and powdered materials. The rotary kiln is mainly used for the primary rough processing of powder or mineral materials, such as in the firing and calcination of cement clinker; the preparation of titanium dioxide from kaolin, the processing of the rare earth industry, etc. Although the output is large, there are disadvantages such as large temperature difference, low temperature control accuracy, inability to seal and achieve precise atmosphere control. Temperature-controlled rotary kiln technology is a technology that uses advanced control systems to ensure that the rotary kiln operates stably within a specific temperature range. It mainly includes control systems, heating systems and transmission systems. Temperature-controlled rotary kilns are widely used in ceramics, metallurgy, electronics, glass, chemicals, machinery, refractory materials, new material development and other fields. They are used for heat treatment, drying, calcination and other processes of materials. Through these technical characteristics, the temperature-controlled rotary kiln can provide efficient, stable and reliable heat treatment solutions for industrial production.

[0003] In most existing temperature-controlled rotary furnaces, during the metal melting process, after the molten metal liquid is discharged from the temperature-controlled rotary furnace, part of the metal liquid will adhere to the inner wall of the temperature-controlled rotary furnace.
