Features
The move-asleep sealing joint is made of graphite ring with spherical surface, with good sealing performance.
The heating elements hanged on three sides of the hearth ensure temperature uniformity.
The refractory lining is made up of fiber blankets with good heat isolation performance.
Atmosphere: H2, N2 or Air. Pressure can be auto-controlled within ±10KPa.
Continuous Loaded by a dosing screw feeder, automatically continuous unload using an air-lock rotary valve.
The rotating speed of the drum and the screw feeder can be stepless-changed.
