Introduction to Industrial Tunnel Furnace Parameters

Introduction to Industrial Tunnel Furnace Parameters

The working principle of tunnel furnace (drying line, standard equipment tunnel drying line) is generally to use far-infrared to heat the furnace, and then the interior is made of ceramic and stainless steel, so that infrared light can shine on every corner of the furnace, and then evenly heat up to transfer energy to objects.

The tunnel furnace is designed and manufactured using advanced foreign technology, with advanced structure, easy disassembly and assembly, and beautiful appearance. High tech insulation materials have good insulation performance and strong insulation properties. The heating technology adopts far-infrared heating technology, with reasonable arrangement of heating elements and low energy consumption. The internal hot air circulation makes the temperature inside the oven more uniform and leak free, ensuring the quality of the oven products.

The energy-saving tunnel furnace adopts an accurate temperature control system and is controlled by a PID microcomputer. There are three internal heating zones for indirect drying. The products heated and dried by the tunnel furnace have low moisture content and are designed for reflow soldering of SMT components, drying, curing, and dispensing of printed circuits, electronic products, and powder materials. The furnace adopts an independent temperature zone isolation structure, heated by far-infrared ceramic heating plates or ceramic black crystal tubes, with a wide infrared irradiation surface and no dead corners. The system can be equipped with an enhanced exhaust mechanism to further improve the temperature uniformity and cleanliness of the product environment. The control adopts a single loop intelligent adjustment method, which has the characteristics of stable temperature control and convenient adjustment. Very suitable for mass production in factories and enterprises.
