Product introduction of trolley tempering furnace
Trolley-type tempering furnace (hereinafter referred to as electric furnace), mainly used for general large and medium-sized metal or alloy parts for heat treatment at rated temperature

The shell of this series of electric furnace is welded by steel plate and section steel, and the trolley is welded by section steel and steel plate. The trolley reduces the heat radiation and convection loss through the soft contact with the furnace lining and the sand seal mechanism, and effectively guarantees the furnace body tightness.

The fan is composed of a blower and a wind deflector. The blower motor and the heating element are electrically interlocked. The heating element can be energized only after the blower is turned on. This ensures that the heating element can work in the ventilation cycle.

Furnace lining: The furnace body of the furnace is made of all fibers. The fibers are customized into modules according to the size of the furnace. The fibers are compressed into blocks for on-site cotton construction. The fixing method is fixed with piercing and hook nails. , And then hooked through the shawl with a hook and nail, and welded to the furnace after tightening. High-aluminum bricks are used for the pressure-resistant part of the trolley, and thermal insulation bricks are used for heat preservation in the lower part.

The furnace door is lifted by rollers on the guide rail. It is rolled up and down and sealed with an advanced spring pressing device. This not only ensures the tightness between the furnace door fibers and the furnace body fibers when it is closed, but also ensures that During the opening and closing process, the fiber will not be damaged by friction. The power of the furnace door and the trolley is provided by an electric motor, and it has a controllable function.

Each moving mechanism of the electric furnace adopts chain control, that is, the power of the heating element is automatically cut off when the furnace door is opened, and the power of the trolley is restored when the furnace door is closed. An accident occurred due to mishandling.

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 the shelving bricks of the shelving trolley, and fixed with high alumina porcelain nails and shelving bricks to prevent them from coming out.

The bottom of the trolley is equipped with a pressure-resistant and high-temperature-resistant cast steel furnace floor to carry the workpiece. In order to prevent the scale generated after the workpiece is heated from falling through the gap between the furnace floor and the heating element and causing damage to the heating element, the contact between the furnace floor and the furnace body is made by inserting contact.

The furnace is divided into multiple zones for temperature control. The furnace temperature control system uses an advanced intelligent temperature controller to achieve the heating and furnace temperature control in the furnace. The system has an advanced intelligent PID control algorithm and a five-digit large LCD display. Setting, self-adaptive function, temperature control and furnace temperature are displayed at the same time, and can be programmed and controlled according to the technological requirements of the workpiece, automatic adjustment and control of heating power in the furnace, convenient operation, supporting control system also has sound and light over temperature alarm, etc. Features. The furnace temperature control system power trigger uses a three-phase three-wire non-contact output module and a bidirectional thyristor to control the temperature accurately and stably. The system is also equipped with a temperature recorder, which can accurately record the temperature of each furnace in time for inspection.
