THD01 Annealing Oven
Application and operating principle
THD01 aluminum collapsible tube annealing oven is a supporting equipment for aluminum collapsible tube production line.
The molecular structure of the extruded aluminum tubes generates stress and it lose flexibility. To de-stress it is annealed at a certain temperature, which makes it soft , burn off the dirt and lubricants from the tube to prepare dirt free surface to receive prints.
The annealing oven adopts the form of electric heating, which is safe and clean. Conveying basket chain puts germ tubes into the "C" basket one by one. The tubes are then driven to the oven where they are heated for 3-5minutes. After that, the tubes are sent to the cooling section and then to the next procedure.
Main features
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. FUJI temperature controller ensures the temperature within plus or minus 2 ℃ of setting temperature.
C. The tube conveying chain adopts continuously variable, which can make the equipment and the last device have the same production speed.
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 before and after, or operate separately.
