Structure Introduction

The resistance furnace is mainly composed of a furnace shell, furnace lining, heating elements, furnace door lifting mechanism, trolley entry and exit mechanism, electrical control system, and other parts.

1. The furnace shell is welded from steel sections and plates, with a beautiful appearance and firm rigidity.

2. The furnace lining is made of high alumina bricks for the inner layer, lightweight clay bricks for the middle layer, and insulation fillers for the outer layer

3. The heating element is made of high-temperature resistance wire wound in a spiral shape and placed on both sides and the bottom of the furnace.

4. Furnace door lifting mechanism: The furnace door is lifted and lowered by the furnace door Composed of rope pulley, bearing, sprocket, balance block, and furnace door clamping device. In order to ensure operational safety, linkage switches are installed on the furnace door and trolley, which are interlocked with the lifting action of the furnace door. When the furnace door is opened, the power supply of the electric furnace is automatically cut off to ensure the safety of the operator.

5. Electrical control system: The temperature control adopts an intelligent adaptive PlD temperature controller, which can be controlled by program and non program control methods according to customer requirements. The output is continuously controlled by a thyristor to achieve uniform and stable temperature control. In addition, it has an over temperature protection function. Once the temperature exceeds the limit, the main heating circuit can be cut off through the protection device to ensure the safety of the equipment and products.
