The common names of muffle furnaces are as follows: electric furnace, resistance furnace, muffle furnace. Muffle furnace is a kind of general heating equipment in laboratory, which can be divided into box furnace, tube furnace, crucible furnace and so on according to the appearance and shape.

The main application areas of muffle furnaces are:

(1) Thermal processing or processing of small workpieces in thermal processing, industrial workpiece processing, cement, and building materials industries.

(2) Pharmaceutical industry: used for drug testing, pretreatment of medical samples, etc.

(3) Analytical chemical industry: as sample processing in water quality analysis, environmental analysis and other fields. It can also be used for petroleum and its analysis.

(4) Coal quality analysis: used to measure moisture, ash content, volatile content, ash melting point analysis, ash component analysis, and elemental analysis. It can also be used as a general-purpose ashing furnace.

 

For the classification of muffle furnaces, they can be classified according to their heating elements, rated temperature, and controllers, as shown below:

(1)  According to the heating elements, there are: electric furnace wire muffle furnace, silicon carbon rod muffle furnace, silicon molybdenum rod muffle furnace;

(2)According to the rated temperature, it is generally divided into: muffle furnace below 1000℃; 1000℃, 1200℃ muffle furnace; 1300℃, 1400℃ muffle furnace; 1600℃, 1700℃ muffle furnace; 1800℃ muffle furnace.

(3) According to the controller, there are the following types: pointer type, ordinary digital display type, PID adjustment controller, and program controller.
