What is the difference between a tube resistance furnace and a box resistance furnace?

  Tube resistance furnaces and box-type resistance furnaces are common laboratory heat treatment equipment. They have their own characteristics and differ in their applications. Next, let’s take a look at the differences and advantages of these two types of resistance furnaces.

Tube resistance furnaces usually use metal tubes or quartz tubes as heating elements with built-in resistance wires. The tubular resistance furnace has the advantages of fast heating speed, high temperature control accuracy, uniform temperature, etc. It has a large heating area and is suitable for a wide range of high-temperature heat treatments. Tube resistance furnaces are commonly used in the glass, ceramic, metal and semiconductor industries and are widely used in processes such as sintering, annealing, heat treatment and drying.

The box-type resistance furnace is a closed structure. The entire furnace body is made of high-density and high-precision fiber furnace, and resistance wires are placed inside the protective layer. Box-type resistance furnaces have the advantages of large size, strong stability, and low operating noise. They are usually equipped with an automatic control system to achieve more precise temperature control. Box-type resistance furnace is suitable for various heat treatment processes, such as annealing, quenching, tempering, roasting and drying. Box-type resistance furnaces are widely used in powder metallurgy, chemical materials research, electronic and electrical industries and other industries.

When choosing the type of resistance furnace, you need to consider not only the size, shape and output of the materials to be processed, but also the heating speed and control accuracy. If you need to heat quickly and evenly and can accommodate large-sized workpieces, then a tubular resistance furnace is a good choice. On the contrary, if you need more precise temperature control and a smoother heating process, then a box-type resistance furnace is the best choice.

In short, Tube resistance furnaces and box-type resistance furnaces each have their own advantages and scope of application. It is very important to select different heat treatment equipment according to specific needs. Our KJ group can also customize the resistance furnace products you need according to customer needs.
