auto screw steel nails austemper carburizing heat treatment furnace

1). Driving system of mesh belt: Driving the stailess steel roller with high temperature resistant through the chain wheel to circulatory drag mesh belt move into the chamber, which can expanding the service life of mesh belt and Reducing furnace heat loss, meanwhile improving more high thermal efficiency.
2). Equipped the fan inside of furnace to ensure temperature uniform and protect (carburizing) atmosphere evenly dispersed, which can improve the carburizing speed and workpiece quality.
3). On the rear of furnace equipped with an exhaust fan for timely discharge waste gas and improve gloss of workpiece surface.
4). On the bottom of the furnace body is equipped with slag removal mouth, which can convenient and clean up the slag.
5). New sealing design of furnace door can save 55-65% atmospher consumption, and also deep permeation, 30-40% higer efficiency than before under the pressure at ≥10-100Pa.
