The Powder Metallurgy Pusher Furnaces is a core continuous high-temperature thermal processing system used in the powder metallurgy industry for the sintering of pressed metal powders. The maximum operating temperature typically ranges from 1100–1400°C, and can exceed 1500°C for hard metal (cemented carbide) applications.
Along its length, the kiln is generally divided into the following zones:
Charging Zone → Preheating Zone → High-Temperature Sintering Zone → Soaking Zone → Cooling Zone → Discharging Zone
Common operating atmospheres include:
Nitrogen (N₂), Hydrogen (H₂), Dissociated Ammonia (N₂ + H₂), and Vacuum
Pusher Furnaces are widely used in industries such as:
Powder Metallurgy, Cemented Carbides, and New Energy Materials
Engineering Approach and Performance Assurance
To address the demanding operating conditions—including high temperatures, controlled atmospheres, mechanical loading, and frequent thermal cycling—we implement stringent standards across the entire process chain, from lining structure design and refractory material manufacturing to on-site installation.
This integrated approach ensures long-term stable operation of the kiln while enabling customers to achieve efficient, high-quality, and scalable production.
