Introduction of liquid crystal ceramic fiber box furnace
The box furnace belongs to the periodic operation type, which is used for heating in the laboratory, industrial and mining enterprises, and scientific research institutions for element analysis and determination, as well as in the quenching, annealing, tempering and other heat treatment of general small steel parts. The high temperature box furnace can also be used for the sintering, dissolution, analysis and other high temperature heating of metals and ceramics.
The main purpose of the ceramic fiber box furnace is to heat the raw materials, blanks and machine parts in the machine industry. For example, the heating of blank before plate rolling and the heating of calcined parts. Heat treatment of other parts and semi-waste products of the machine to improve its machine functions, such as rod quenching, tempering, annealing, normalizing, gas carburizing, nitriding, etc. It is also used for sintering, brazing, smelting of low melting point nonmetals in all resistance furnaces and heating of ceramic glass industry.
The ceramic fiber box furnace can be classified according to its heating element, rated temperature and controller. See the following for details:
1) According to the heating elements, there are: electric furnace wire box furnace, silicon carbide rod box furnace, silicon molybdenum rod box furnace;
2) According to the rated temperature, it is generally divided into 1200 ℃ box furnace, 1400 ℃ box furnace and 1700 ℃ box furnace;
3) According to the controller, there are the following types: pointer table, ordinary digital and LCD display table, PID adjustment control table, and program control table; According to thermal insulation materials, there are two types: ordinary refractory brick and ceramic fiber. Therefore, users must write clearly in the contract when purchasing products to prevent suppliers from playing tricks.
