A tubular furnace is a versatile heating device widely used across various industries and research fields. It is designed to provide high-temperature environments for processes such as powder roasting, ceramic sintering, material treatment, and high-temperature experiments. The furnace's cylindrical heating chamber allows for uniform temperature distribution, making it ideal for applications in ceramics, metallurgy, electronics, and more. Its ability to handle different atmospheres (e.g., inert, oxidizing, or reducing) makes it suitable for specialized tasks like annealing, sintering, and flue gas treatment. This equipment is essential in universities, research institutes, and industrial settings for advancing material science and production processes.
