If the car annealing furnace is not used well in the use process, it will lead to a series of failures. In order to use the car annealing furnace normally, daily maintenance and daily use precautions are what we must know. Reducing losses is also a way for enterprises to increase profits.

The platform of the trolley annealing furnace is equipped with a cast steel hearth plate resistant to pressure and high temperature to bear the workpiece. In order to prevent the oxide generated after the workpiece heating from falling into the heating element through the gap between the furnace bottom plate and causing damage to the heating element, the plug-in contact between the furnace bottom plate and the furnace body is adopted. In order to ensure normal use, it is necessary to often purge the oxide under the bottom plate of the annealing furnace, generally purge once a week. When purging, the furnace bottom plate is lifted, and the oxidized skin in the resistance wire groove is purged with compressed air, and attention is paid to preventing the oxidized pickup from causing short circuit in the furnace wire.

The furnace door device of the trolley annealing furnace is composed of the furnace door, the furnace door lifting mechanism and the furnace door pressing device. The shell of the furnace door of the trolley annealing furnace is a solid frame structure welded by the section steel and the plate, and the interior is stacked with the refractory fiber pressing module, which requires good thermal insulation performance and light weight. The lifting device of the furnace door adopts the electric device, which is mainly composed of the furnace door frame, the furnace door lifting beam, the reducer, the sprocket, the drive shaft and the bearing, etc. The furnace door lifting is driven by the positive and negative transmission on the reducer. The furnace door lifting reducer is also equipped with a brake device, which can effectively prevent the furnace door from displacing during the lifting process.

The pressing device of the furnace door of the trolley annealing furnace adopts the advanced spring pressing structure in China. When the furnace needs to be lifted, the dead weight of the furnace door will automatically loosen the furnace door through the lever, and then rise after moving horizontally for a certain distance. When the furnace door falls into place and the furnace door of the trolley annealing furnace is put down to the pulley on the trolley and needs to be pressed tight, The pressure device of this structure makes no friction between the fiber plane on the furnace door and the cotton of the furnace mouth. It has the characteristics of good safety performance and long operation mission. The trolley frame of the trolley annealing furnace is welded with section steel, and its rigidity ensures no deformation under full load. The interior is built with firebrick, the collactible part and the bearing part are built with heavy brick to enhance the strength of the furnace lining structure. The walking structure of the trolley is self-propelled, and the driving wheel is driven by the reducer sprocket to walk on the track.
