The Steel Belt Furnace is a high-efficiency, continuous thermal processing system designed for calcining, reducing, and sintering of various metal powders, including iron powder, copper powder, cobalt powder, molybdenum powder, and tungsten powder. By conveying metal powder directly on a high-grade 310S stainless steel belt and heating it under a controlled atmosphere, this furnace provides consistent temperature control and uniform product quality, making it ideal for demanding powder metallurgy applications.
Metal powder is uniformly distributed on the moving steel belt, which passes through several controlled heating zones. The system supports precise regulation of temperature, belt speed, and process atmosphere, allowing it to meet the exact requirements of sintering and reduction processes.
The complete Steel Belt Furnace system consists of the following sections:
Includes a loading table and entrance muffle.
Equipped with a mobile feeder car that moves laterally with the belt to ensure uniform distribution of powder across the belt surface.
Furnace Lining: Built with ultra energy-saving structure:
The base insulation uses high-density insulating bricks (0.8 bulk density).
Sidewalls are lined with aluminum silicate fiber.
The furnace shell is reinforced with asbestos board to minimize thermal conductivity at lower temperatures.
The furnace lid is constructed with fiber blanket modules, anchored using a suspended ceiling structure, providing outstanding thermal insulation, low heat storage, and easy maintenance.
Heating Chamber (Furnace Tank):
Made from 8mm thick 310S stainless steel, bent and welded with circular reinforcing ribs.
The bottom is supported with silicon carbide plates, ensuring flat and uniform heat distribution at high temperatures and preventing deformation.
Sealing System:
The inlet and outlet use roller sealing, gas curtain, or fiber curtain systems to maintain a tight seal and reduce protective gas consumption.
Enables gradual cooling before product exit to prevent thermal shock.
Collects the treated metal powders for downstream processing.
Includes motor, frequency converter, reducer, drive rollers, and tensioning unit.
Belt material: 310S stainless steel, 340 mm wide, approx. 35.6 meters long.
Belt drive is powered by a cycloidal gear reducer combined with a worm gear reducer, supporting variable speed control up to 150 mm/min.
Rollers are drum-shaped for automatic belt centering, while a gravity-based tensioning system ensures consistent tensioning during operation.
Temperature Control: Managed via PLC + Touch Screen interface with SHIMADEN (Japan) intelligent temperature controllers for accurate process regulation.
Heating Elements: Made of high-temperature OCr21A6Nb resistance wire (imported).
Power Adjustment: Heating tubes are controlled by Taiwan YANGMING SCR regulators.
Thermocouples: Insert-type thermocouples with reserved measuring ports provide real-time monitoring.
