In the field of industrial production, tunnel furnaces are playing an increasingly important role as efficient and continuous heating equipment. The working principle of a tunnel furnace is to use heat transfer methods such as heat conduction, convection, and radiation to evenly heat materials during transportation, achieving processes such as drying, baking, and solidification.
Structurally, tunnel furnaces are usually composed of furnace body, conveying system, heating system, temperature control system, and ventilation system. The furnace body is generally welded with high-quality steel, which has good insulation performance and can effectively reduce heat loss. The conveying system can choose chain conveying, mesh belt conveying, or roller conveyor according to the characteristics of the materials and production needs, to ensure that the materials pass through the furnace stably and continuously. The common heating systems include electric heating, gas heating, and steam heating, which can be selected according to the actual situation. The temperature control system can accurately control the temperature inside the furnace through high-precision temperature sensors and intelligent controllers, ensuring the consistency of product quality. The ventilation system is responsible for discharging exhaust gas and moisture from the furnace, maintaining a good working environment inside the furnace.
Tunnel furnaces have the advantages of high production efficiency, uniform heating, and high degree of automation, and are widely used in multiple industries such as electronics, food, chemical, ceramics, etc. With the continuous improvement of industrial automation, the market demand for tunnel furnaces will also continue to grow, providing strong support for the efficient development of industrial production.
