After extrusion, aluminum slugs are shaped into germ tubes. The change of metal molecular structure generates stress and makes the tubes lose flexibility. To remove the stress and meet the requirements of tubes, it is necessary to carry out stress annealing treatment on germ tubes. After the annealing process, the tubes get soft. And meanwhile, the release agent on the surface of tubes volatilizes completely, which ensures the adhesion of internal coating and base coating.
The annealing oven adopts the form of electric heating, which is safe and clean. Conveying chain puts germ tubes into the "C" basket respectively. The tubes are then driven to the oven where they are heated for 3-5mins. After that, the tubes are sent to the cooling section and then to the next procedure.
A. Tube range: φ16-φ25mm or φ25-φ35mm
B. Tube length: ≤180mm
C. Production speed: 120 tubes/min
D. Electric heating power: 52KW
E. Working temperature: 200℃-450℃
F. Dimensions: 3600*1400*2500mm
G. Weight: about 3500KG
A. The electric heating components adopt stainless steel thermal resistance and have features of uniform heating and easy operation. Heating components are easy to detach and replace.
B. The internal temperature of oven is uniform due to force circulation of the hot air. Thus the effect of annealing is excellent and the quality of products is guaranteed. FUJI temperature controller ensures the temperature within plus or minus 2 ℃ of setting temperature.
C. The tube conveying chain adopts continuous viable, which can make the equipment and the last device have the same production speed. The sprayer machine provides main driving force for the chain.
D. The oven chamber adopts suspended structure which is convenient for maintenance and makes the conveying basket more stable during the operation of the furnace cavity, reducing the incidents of dropping and crushing tubes, so as to improve the qualified rate of products.
E. The machine is equipped with a single driving motor. It can operate synchronously with the equipment in front and behind, or operate separately.
