Box type resistance furnace is an industrial heating equipment, also known as an industrial heat treatment electric furnace. It consists of a box, heating elements, temperature control system, and electrical control system. The box is welded from metal plates and lined with high-temperature resistant materials, commonly used materials include ceramic fibers, graphite, etc. Heating elements generally use resistance wires or electric heating tubes, which are energized to heat the object. The temperature control system generally adopts PID control method, with high control accuracy. The electrical control system includes electrical components such as wiring terminals, circuit breakers, thermal relay protectors, temperature controllers, and heating elements. Box type resistance furnace is suitable for heat treatment, annealing, tempering, quenching and other processes of various metal and non-metallic materials.

Box type resistance furnaces have the following advantages:

1. Strong stability: The shell of the box type resistance furnace is welded with high-quality steel plates, and a reasonably distributed heating element is installed inside to ensure uniform heating and stable temperature. Therefore, the box type resistance furnace has good temperature control accuracy and stability.

2. Strong adaptability: Box type resistance furnaces are suitable for various industrial production fields and can be used for drying, sintering, heat treatment, annealing, quenching and other processes, meeting the heating needs of different industries and products.

3. Convenient operation: The operation panel design of the box type resistance furnace is simple and clear, equipped with functional modules such as digital display screen, temperature controller, timer, etc., which can easily adjust the heating temperature and time, achieving intelligent control.

4. Energy conservation and environmental protection: The box type resistance furnace adopts high-quality insulation materials and efficient heating elements, which can quickly heat up, efficiently save energy, and have no pollution to the environment.

5. Convenient maintenance: The box type resistance furnace has a simple structure, is easy to clean and maintain, and has a long service life, reducing the cost of repair and replacement for enterprises.
