RHF-1500L Roller Table Atmosphere Furnace with 1500°C Max Temperature and 112L Capacity for Battery Material Sintering
The RHF-1500L furnace is engineered to replicate the conditions of large continuous kilns on a pilot scale, enabling researchers to determine optimal sintering parameters for battery materials at reduced cost and complexity. Its design supports the production of cathode materials and hard carbon precursors, essential for battery development and testing.
This furnace incorporates a ceramic roller table positioned between two independently controlled heating zones, each equipped with silicon carbide (SiC) rod heating elements capable of reaching a maximum temperature of 1500°C. The heating module is housed within a stainless steel vacuum chamber, allowing precise atmosphere control from oxygen-rich to inert gas environments, critical for material quality and process reproducibility.
Key Features
- Two heating zones with SiC rod elements providing rapid and uniform heating up to 1500°C.
- Ceramic roller table facilitates continuous sample movement simulating industrial kiln processes.
- Stainless steel vacuum chamber with KF 40 port, vacuum gauge, and gas inlet/outlet for controlled atmosphere processing.
- Dual programmable temperature controllers with ±1°C accuracy and PID control for precise thermal profiles.
- Integrated oxygen analyzer and three flowmeters for real-time gas composition and flow regulation.
- Maximum heating rate of 10°C per minute with a constant temperature zone of 660 mm.
