Sealed box furnace

Sealed box furnace description:
Sealed box is used for professional heat treatment furnaces industrial furnaces, heat treatment effect. Sealed box furnace are mainly the following
Positive stove sealed box:
Sealed box is a dual chamber structure furnace, muffle heating chamber is no structure, using advanced refractory brick, door cylinder individually designed using advanced compression seal structure, good sealing, no leakage atmosphere. Box is using electric heating furnace, radiant tube evenly distributed on both sides and at the bottom of the furnace, heat-resistant steel roof with a stirring fan to ensure temperature uniformity. Fengdong Box normalizing furnace heating process pass into the protective atmosphere, the workpiece without oxidation. Sealed box is out of the stove automatic and manual feeding mode (optional), box-type furnace cooling chamber is equipped with a large flow variable speed cooling fan, cooling speed.
Sealed box annealing furnace:
Sealed box annealing furnace for the single-chamber structure, the heating chamber with advanced refractory brick, sealed box annealing furnace door are individually designed cylinder compression seal structure, good sealing, no leakage atmosphere. Box is using electric heating furnace, radiant tube evenly distributed on both sides and at the bottom of the furnace, heat-resistant steel roof with a stirring fan to ensure temperature uniformity. Fengdong box annealing furnace heating process pass into the protective atmosphere, the workpiece without oxidation.
