Hot zone refers to the central region of a tube furnace or rotary kiln where the temperature reaches its maximum. This area contains the most intense heating elements and is designed to deliver consistent, uniform heat to materials under treatment. With carefully engineered insulation and heating control, the hot zone ensures precise thermal conditions are maintained—making it essential for processes such as sintering, calcination, pyrolysis, or other thermal treatments in both laboratory-scale and pilot-scale furnaces.
