After many years of high-temperature muffle furnace/box-type resistance furnace use, the furnace wire may break. Many users do not know how to deal with this situation during the maintenance process. Generally speaking, the high-temperature muffle furnace/box-type resistance furnace is divided There are two types of ceramic liner and refractory brick liner;
If the resistance wire of the high-temperature muffle furnace/box-type resistance furnace in the refractory brick liner is broken, you first need to see how the resistance wire of the high-temperature muffle furnace/box-type resistance furnace is installed?
(1) If it is embedded as a whole, the furnace needs to be replaced.
(2) If it is fragmented, then which side is broken can be replaced.
The same is true if the liner is made of ceramic fiber. You must first look at how the resistance wire of the high-temperature muffle furnace/box-type resistance furnace is installed?
(1) If it is embedded as a whole, the furnace needs to be replaced.
(2) If it is a split type, you can replace which side is broken. When replacing, open the top cover, take out the insulation layer, and then take out the broken furnace and replace it with a new one. Enough.
(3) If it is heated by a silicon carbide rod, it is generally sufficient to directly replace the silicon carbide rod.
