Product description

    The trolley type electric resistance furnace is a national standard energy-saving periodic working furnace, which has an ultra-energy-saving structure and adopts a fiber structure, and the power saving is as high as 60%. The production adopts composite high-aluminum porcelain nail set, trolley anti-collision sealing brick, automatic sealing trolley and furnace door, integrated rail, no basic installation, and can be used on horizontal ground. Mainly used for high chromium, high manganese steel castings, ductile iron, rolls, steel balls, 45 steel, stainless steel, etc. for quenching, annealing, aging and heat treatment of various mechanical parts

    The furnace door device is mainly composed of the furnace door frame, the furnace door lifting beam, the reducer, the sprocket, the transmission shaft and the bearing, etc. The furnace door is lifted and lowered by the forward and reverse transmission on the reducer to drive the lifting and lowering of the furnace door. The furnace door pressing device adopts the domestic advanced spring-type pressing structure. When the furnace needs to be lifted, the self-weight of the furnace door will automatically loosen the furnace door through the lever, and horizontally move out a certain distance and then rise, when the furnace door is lowered into position, the furnace door When it is put down on the pulley on the trolley to be pressed, the elastic force of the spring is used to move the furnace door horizontally into the compression seal state by the lever. The pressing device of this structure makes the fiber plane on the furnace door and the mouth cotton. There is no friction between them, and it has the characteristics of good safety performance and long mission.

    The frame of the trolley is welded by profile steel, and its rigidity ensures that it will not deform under full load. The interior is made of refractory bricks, and the easy-to-collision parts and load-bearing parts are built with heavy bricks to enhance the structural strength of the lining. The walking of the trolley adopts a self-propelled structure, and the transmission sprocket of the reducer drives the walking wheels to walk on the track. The trolley seal adopts automatic labyrinth structure and soft contact double seal. The trolley enters the furnace and acts through the cam and the roller slope, and automatically rises and seals. The trolley is opened and interlocked, that is, after the furnace door is slightly opened, the heating element is automatically cut off, and the power of the heating element is restored.

    In order to shorten the cooling process time, the top of the furnace may be provided with an exhausting device for accelerating cooling, and cooling to a certain temperature to open and close the opening operation is performed by the operator on the side of the furnace by manual mechanism or automatic control. And optional trolley tilting unloading mechanism. The electronic control part mainly includes two parts: temperature control and operation. The temperature control adopts the domestic digital display meter AC contactor to implement the common position control, and the recorder also records the complete process curve and can over-temperature alarm; the operation adopts the button and the light display to realize the entry and exit of the trolley and the heating element on and off. The operation of the door door lifting and the like is controlled, and an interlocking device is provided. When the furnace door is lifted or closed to a certain position, the trolley can be operated, which is safe and reliable.
