Briefly describe the seven characteristics of tubular electric furnace

The characteristic of the tubular electric furnace is that it adopts a special sealed structure and can be vacuumed. Due to the improvement of airtightness, the furnace space can not only maintain an oxidizing atmosphere (in the air) and a neutral atmosphere (nitrogen or carbon dioxide, etc.), but also can pass reducing gas. The furnace tube of the tubular electric furnace is generally made of heat-resistant steel, quartz glass, ceramic tube and other materials. So are there any other features of the tubular electric furnace?

1. The shell of the tubular electric furnace is treated with high temperature resistant and corrosion resistant paint; it is beautiful and durable.

2. The console adopts an intelligent PID digital display controller, which has good stability and high precision, equipped with an ammeter, and a novel structure.

3. The door of the tubular electric furnace is thickened and reinforced to prevent deformation.

4. The lining of the tubular electric furnace is made of high-purity alumina, polycrystalline mullite and thermal insulation cotton, which has a good thermal insulation effect.

5. Tubular electric furnace can choose single set point or 50-segment programmable controller. Energy-saving ceramic fiber material and double-layer structure can reduce the surface temperature to normal temperature. Long uniform temperature zone, easy operation, reliable sealing, high comprehensive performance index.

6. The tube electric furnace also has the function of constantly detecting the temperature (the actual temperature of the furnace is also displayed when it is not heated, so that it is convenient to observe the temperature of the furnace at any time). With overload protection and short circuit protection.

7. The furnace shell is made of high-quality steel plate by folding and welding. The working chamber is a furnace made of refractory materials. The heating element is placed in it. The furnace and the shell are built with insulation materials.

In fact, there are many types of electric tube furnaces, such as single temperature zone, dual temperature zone, and three temperature zone. These furnaces have the characteristics of safety and reliability, simple operation, high temperature control accuracy, good heat preservation effect, large temperature range, high furnace temperature uniformity, and multiple temperature zones.
