Detailed :

The function of aluminum alloy annealing furnace is as follows

The function of annealing furnace is to heat the workpiece to a predetermined temperature cool it slowly after holding time. The details are as follows:

1. Eliminate all kinds of structural defects residual stresses caused by casting, forging, rolling welding of iron steel, prevent deformation cracking of workpieces.

2. Soften the workpiece for cutting.

3. Refine the grain structure to improve the mechanical properties of the workpiece.

4. Prepare for heat treatment (quenching tempering).

Aluminum plate annealing furnace is mainly composed of holding furnace body, furnace door device, heating system, hot air circulation system, trolley device electrical control system. The heat preservation furnace body is an all metal box structure welded by two layers of steel plates inside outside. The middle of the furnace is filled with acid aluminum fire-resistant fire-resistant fiber cotton, which can reduce the temperature rise of furnace wall. The furnace door device adopts manual push-pull split door pneumatic lifting furnace door, manual spinning pneumatic connecting rod type four point balance pressing mechanism is adopted for furnace door pressing. The heating system can be suitable for diesel oil, LNG / natural gas, LPG / LPG as fuel heating resistance heating. In order to ensure the uniformity of furnace temperature, axial-flow centrifugal hot-air circulating fan with large air volume is set at the top side of furnace, the hot-air circulation diversion system in furnace is reasonably configured to make the air distribution in the furnace uniform, the temperature difference in the furnace is small (± 5 ℃), the heating speed heating quality are guaranteed. The type of trolley self-propelled trolley can be used. The temperature control system uses PID zero crossing trigger thyristor intelligent meter to control temperature. In addition, it is equipped with multi-point paperless recorder to record the temperature alarm of over temperature to ensure that the workpiece is over temperature. The mechanical transmission part adopts interlock control, that is, after the furnace door is opened, the power supply of ventilator heating element will be cut off automatically. Only after the furnace door is closed in place can the power supply of fan device heating element be connected to prevent malfunction accident caused by misoperation.
