There are many types of experimental electric furnaces, but they can be roughly classified from the following aspects:
From the shape of the furnace, it can be divided into: box-type resistance furnace and tube-type resistance furnace;
2. From the operating procedures, it can be divided into: manual programming resistance furnace and artificial intelligence resistance furnace;
3. From the atmosphere conditions required for the experiment, it can be divided into: oxidation atmosphere resistance furnace and vacuum atmosphere Resistance furnace.
4. From the maximum temperature, it can be divided into: low temperature resistance furnace (below 600℃), medium temperature resistance furnace (600℃-1000℃), high temperature resistance furnace (1000℃-1700℃), ultra-high temperature Resistance furnace (1800℃-2600℃).
