Description

Technical Field

[0001] This utility model relates to the field of fire assay apparatus technology, specifically an electric furnace that is easy to maintain and repair. Background Technology

[0002] Replacing silicon carbide rods in a traditional electric furnace requires two people to remove the heavy exhaust hood, and then a person to climb a ladder to the top of the furnace to remove the connecting strips and screws and nuts at the top and bottom of the silicon carbide rods before replacement. Although there is a thick heat insulation layer on the top and around the furnace, the temperature at the top is still high, which can easily cause burns. The operation is time-consuming and laborious, and climbing to a height is also unsafe.

[0003] Traditional electric furnaces have their wiring at the bottom of the circuit. When the furnace is hot, molten slag drips from the furnace chamber and can easily fall onto the wires at the bottom of the furnace, burning them, causing short circuits, damaging the circuit, or even causing a fire.
