Tubular furnace, as the name suggests, is a type of heating equipment with a tubular structure in the hearth. It usually consists of furnace tubes, heating elements, control systems, and auxiliary equipment. The furnace tube is the main part of the tube furnace and is usually made of materials that are resistant to high temperatures and corrosion, such as quartz, ceramics or metals. The heating element is responsible for providing the heat to bring the material inside the furnace tube to the desired heating temperature. The control system is used to precisely control the temperature in the furnace and ensure the stability and safety of the heating process.
