The trolley tempering furnace is mainly used for heat treatment of general large and medium-sized metal or alloy parts at rated temperature.
The tempering furnace shell of the trolley is welded by steel plate and section steel. The trolley is welded by steel and steel plate. The trolley passes the soft contact with the lining and the sand sealing mechanism to reduce heat radiation and convection loss, and effectively ensure the sealing of the furnace body.
The ventilator consists of a blower and an air deflector. The blast motor is electrically interlocked with the heating element. The heating element can only be energized when the blower is turned on. This ensures that the heating element can operate under ventilation.
The trolley is equipped with a cast steel furnace bottom plate with pressure and high temperature resistance to carry the workpiece. In order to prevent the oxide scale generated after the heating of the workpiece from falling into the periphery of the heating element through the gap between the furnace bottom plates, the heating element is damaged, so that the furnace bottom plate and the furnace body are in a plug-in contact.
The lifting and lowering of the furnace door is realized by rolling the roller on the guide rail and rolling up and down, and is sealed by an advanced spring pressing device, which ensures the sealing and sealing between the door door fiber and the furnace body fiber when closing, and ensures the sealing. The fibers are not rubbed during the opening and closing process. The power of the furnace door and the trolley is provided by the electric motor and has a controllable function.
The movable mechanism of the electric furnace adopts interlocking control, that is, the power supply of the heating element is automatically cut off after the furnace door is opened, and the power supply when the trolley is walking is resumed; the power supply of the trolley traveling motor is automatically cut off after the furnace door is closed, and the power supply of the heating element is restored to prevent the power supply of the heating element from being prevented. An accident occurred due to a misoperation.
The heating element is made of high-temperature resistance alloy wire and wound into a strip shape and a spiral shape, which are respectively hung on the furnace side and placed on the trolley wire brick of the trolley, and fixed by high-aluminum porcelain nails and wire-bringing bricks to prevent the escape.
The trolley tempering furnace is controlled by multiple zones. The furnace temperature control system uses advanced intelligent temperature controller to realize the heating and furnace temperature control in the furnace. The system has advanced intelligent PID control algorithm, five large LCD display, perfect Self-tuning, adaptive function, temperature control and furnace temperature display at the same time, and can be programmed and controlled according to the process requirements of the workpiece, automatically adjust and control the heating power in the furnace, easy to operate, and the supporting control system also has sound and light over-temperature Alarm and other functions. The power control of the furnace temperature control system adopts a three-phase three-wire non-contact output module supporting two-way thyristor, and the temperature control is precise and stable. The system is equipped with a temperature recorder to record the temperature of each furnace in time for accurate inspection.
All-fiber trolley tempering furnace products can be professionally designed and manufactured according to customer requirements.
