The Atmosphere Furnace is a specialized industrial thermal processing equipment designed for the continuous sintering of powder materials under precisely controlled atmospheres, such as nitrogen. As a high-performance Controlled Atmosphere Furnace, it effectively prevents oxidation during high-temperature treatment, ensuring high density, excellent mechanical strength, and dimensional stability of sintered products.
Compared to traditional batch kilns, this Atmosphere Roller Conveyor Furnace offers superior production efficiency, precise temperature control, and stringent atmosphere management, making it an indispensable part of modern automated manufacturing lines.
The kiln body of this Atmosphere Furnace is divided into transition, heating, cooling, and water-cooling zones. The internal roller conveyor system utilizes silicon carbide ceramic rollers, with metal-axle ceramic rollers positioned at both the inlet and outlet sections.
To ensure excellent insulation and airtightness, the kiln is constructed using lightweight mullite refractory bricks and externally lined with ceramic fiber. This design ensures oxygen levels remain below 10 ppm, meeting the stringent requirements of Nitrogen Atmosphere Furnaces.
This Protective Atmosphere Furnace uses a positive pressure nitrogen atmosphere design, effectively preventing oxygen infiltration during sintering. The nitrogen gas is preheated to improve thermal efficiency and further stabilize the controlled atmosphere conditions.
The cooling zone features multi-point nitrogen gas injection, efficiently cooling the workpieces while preventing oxidation. A serpentine water jacket combined with airflow-assisted cooling further accelerates temperature reduction, meeting the fast-paced demands of continuous atmosphere sintering furnaces.
Heating is achieved through quartz tubes embedded with iron-chromium-aluminum alloy (FeCrAl) heating wires, ensuring uniform heating across the work zone. The system uses multi-zone proportional control for accurate temperature management, essential for high temperature atmosphere furnace operations.
Equipped with PLC automation, touchscreen interface, and advanced temperature control modules, this Industrial Atmosphere Furnace uses K-type thermocouples for real-time temperature feedback. Additional safety features include over-temperature protection and continuous data recording via a paperless recorder, ensuring process traceability.
The ceramic roller chain transmission system provides adjustable speed control from 0 to 300 mm/min, ensuring stable and reliable product transfer through each temperature and atmosphere zone.
