What Is Easy To Overlook When Installing Silicon Carbide Rods?

1. When the silicon carbide rods are installed, they should not be in contact with the insulation materials, and should be separated by high-temperature insulated porcelain pipes. In order to avoid arcing due to leakage, causing the wall to melt.

The heated workpiece should not contain too much moisture and should be dried in advance to avoid affecting the life of the rod. If it is a new kiln or a kiln that has not been used for a long time, old rods must be used for kiln drying, and new rods must not be used for baking kilns.

2. In order to ensure that the furnace temperature and the rods bear the load uniformly, the group must be matched before installation, and the resistance deviation of each group of silicon carbide rods shall not exceed 10%. The resistance tolerance of the matching resistance is:

≥￠ 12mm rod with resistance, resistance tolerance ≤ 0.2 Ω

≤￠ 8mm rod with resistance, tolerance of resistance value ≤ 0.5 Ω

3. When the silicon carbide rod is used in hydrogen, the rod body will become brittle and shorten the life. Silicon carbide rods will corrode in contact with alkali metals, alkalis, silicates, borides, etc., so avoid contact with the rods.
