Product advantages
Continuous Aluminum Radiator Brazing Furnace
1). Driving system of mesh belt: Driving the stainless steel roller with high-temperature resistance through the chain wheel to circulatory drag mesh belt move into the chamber, which can expand the service life of the mesh belt and Reduce furnace heat loss while improving higher thermal efficiency.
2). The furnace is equipped with a fan to ensure uniform temperature and protect the evenly dispersed (carburizing) atmosphere, which can improve the carburizing speed and workpiece quality.
3). On the rear of the furnace, equipped with an exhaust fan for timely discharge of waste gas, improved the workpiece surface gloss.
4). The bottom of the furnace body is equipped with a slag removal mouth, which is convenient for cleaning up the slag.
5). The new sealing design of the furnace door can save 55-65% of atmosphere consumption, deep permeation, and 30-40% higher efficiency than before under pressure at ≥10-100Pa.
