How to distinguish the classification of muffle furnace

The muffle furnace is also called box-type resistance furnace, experimental electric furnace, and high-temperature electric furnace. It is a universal heating device. Classified according to different indicators, it can be roughly divided into the following categories:

1. According to the heating elements, there are: electric furnace wire muffle furnace, silicon carbide rod muffle furnace, silicon molybdenum rod muffle furnace;

2. Distinguish by using temperature: box muffle furnace below 1200 degrees (resistance wire heating), 1300 degrees muffle furnace (heating by silicon carbide rods), silicon molybdenum rods for heating above 1600 degrees;

3. According to the controller, there are the following types: PID adjustment control muffle furnace (SCR digital display temperature controller), programmable control;

4. According to the insulation materials, there are two types: ordinary refractory brick muffle furnace and ceramic fiber muffle furnace. The muffle furnace of the ceramic fiber furnace has better insulation performance, light weight, and better energy-saving effect than ordinary refractory bricks. If the budget is sufficient In this case, ceramic fiber muffle furnace should be selected.

5. Distinguish according to appearance: integrated structure box type resistance furnace and split structure box type resistance furnace. It is more troublesome to connect the thermocouple by yourself in the split type. Nowadays, the integrated type is generally used.

The above is the knowledge of simple muffle furnace classification. According to the classification, it will be of great help to your own purchase.
