With rich market knowledge as well as experience, we have been able to emerge as a trusted manufacturer and supplier of Annealing Furnace. It is used to alter the chemical or physical properties of a metal to make it more ductile and reduce its hardness. Our diligent manpower manufactures this machine using optimum grade materials. The internal temperature of furnace is uniform due to force circulation of the hot air. Thus the effect of annealing is excellent and the quality of products is guaranteed. We offer Annealing Furnace at cost effective prices to clients.
- Uniform heating
- Easy operation
- Equipped with a single driving motor
Application and operating principle
YR03B annealing oven is supporting equipment for aluminum collapsible tube production line.
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 oven uses gas and heating circle to provide clean and energy-efficient heating power. Conveying basket 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.
- SIEMENS PLC controls the temperature automatically. SICO burn-up device can regulate the fire according to the internal temperature of the oven.
- The machine adopts hot air recycling system(heating box, fan and air channel). The box employs convective mixing technology which can ensure uniform heating. The internal temperature of oven is uniform due to the circle of the hot air. Thus the effect of annealing is excellent and the products are of high quality.
- The machine is safe, convenient and energy-efficient. It can not only use natural gas, but also liquefied petroleum gas. Using gas for heating is both effective and economical.
- 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.
- 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.
