Box-type resistance furnace which is also known as muffle furnace; it's the basic heating equipment for laboratory use. Its wide application areas covering industrial & mining enterprises, scientific research institutes, universities, laboratories and other experiments purpose. The resistance furnace is the necessary equipment for sintering, melting and heat treatment of the material and volatile experiments.
1. The appearance is treated with high temperature resistant and corrosion resistant paint.
2. The console adopts an intelligent PID digital display controller with good stability and high precision. It is equipped with an ammeter and has a novel structure.
3. The furnace door is thickened and reinforced to prevent deformation.
4. The furnace lining is made of high-quality thermal insulation cotton, which has good thermal insulation effect.
5. The furnace temperature is constantly detected (the actual temperature of the furnace is also displayed even without heating, making it easy to observe the furnace temperature at any time).
6. The wiring is simple, the diagram is clear, and the operation is convenient.
7. With overload protection and short circuit protection.
8. The furnace shell is made of high-quality steel plates that are hemmed and welded. The working chamber is a furnace made of refractory materials. The heating element is placed in it. The space between the furnace and the shell is built with insulation materials.
Box-type resistance furnaces convert electrical energy into heat energy through heating coils or resistance wires, and transfer heat energy through the air in the box.
Box-type resistance furnace is an electric furnace that uses Joule heat generated by current passing through conductors as the heat source.
Box-type resistance furnace uses electricity as the heat source, converts electrical energy into heat energy through electric heating elements, and heats metal in the furnace. The resistance furnace has a high thermal efficiency compared to the flame, which can reach 50-80℅. The thermal system is easy to control, the working conditions are good, and the furnace body has a long life. It is suitable for heating workpieces with strict requirements, but the power consumption is high.
According to the heat transfer mode, box-type resistance furnaces are divided into radiation resistance furnaces and convection resistance furnaces. Radiation resistance furnaces mainly use radiation heat transfer, and the convective heat transfer effect is small; convection resistance furnaces mainly use convective heat transfer, often called air circulation resistance furnaces, which rely on hot air for heating, and the furnace temperature is usually lower than 650°C. .
According to the way of electric heat generation, resistance furnaces are divided into two types: direct heating and indirect heating.
