Introduction to the scope and classification of muffle furnace

muffle furnace is a cyclically operating general heating equipment, which can be used in laboratories, industrial and mining enterprises and scientific research units for elemental analysis and heating of small steel parts in the process of quenching, annealing and tempering.

After understanding the classification of muffle furnaces, let’s understand the scope of application:

(1) Thermal processing of small workpieces, cement and building materials industries.

(2) Pharmaceutical industry: drug testing, medical sample pretreatment, etc.

(3) Analytical Chemistry: Sample processing in the field of water quality analysis and environmental analysis. The muffle furnace can also be used for petroleum and its analysis.

(4) Coal quality analysis: used to determine moisture, ash, volatile content, ash melting point analysis, ash composition analysis, element analysis. It can also be used as a general ash furnace.

At the same time, the classification of furnaces can be classified according to the rated temperature and the difference of the controller, as follows:

According to the rated temperature, it is generally divided into: 1000°C or less, 1000°C, 1200°C, 1300°C, 1400°C, 1600°C, 1700°C, 1800°C muffle furnace.

According to the controller, there are the following types: pointer table, ordinary digital display table, PID adjustment control table, program control table; according to the insulation material, there are two types: ordinary refractory brick and ceramic fiber.
