Silicon carbide rods are prone to cracking when exposed to moisture, and GD rod contacts are prone to breakage when exposed to moisture. Therefore, silicon carbide rods are Pay attention to moisture-proofing during storage, installation and use, so as not to affect its lifespan.
In order to ensure that the furnace temperature and the rods bear a uniform load, the groups must be matched before installation. The resistance value deviation of each group of silicon carbon rods shall not exceed 10.
Silicon carbide rods are hard and brittle, so be careful when handling, unpacking, installation, and maintenance to avoid damage.
When the electric furnace starts to be powered on, the voltage should be gradually and slowly increased, and the full load should not be added at once, otherwise the silicon carbide rod will be damaged due to excessive inrush current.
After long-term use, when individual rods are damaged and need to be replaced, new rods that meet the matching requirements must be selected and replaced according to the resistance growth. If the rods in the furnace are damaged a lot or the resistance increases too much, all silicon carbide rods should be replaced.
Keep the rod holes on both sides of the furnace wall as concentric as possible. The diameter of the hole is 1.5 times the diameter of the installed silicon carbide rod, and the gap is plugged with asbestos or aluminum silicate fiber.
After long-term use of silicon carbide rods, the resistance will slowly increase. To ensure normal operation and extend service life, it is best to be equipped with a corresponding voltage regulating transformer.
The white stuff on both ends of the rod is sprayed aluminum, which is mainly to reduce the contact resistance between the rod clamp and the rod. It is easy to deteriorate after getting wet. If the deterioration is found, it should be removed in time, spray aluminum again or use aluminum foil paper to heat the rod. When used with metal clips
After wiring, carefully check whether the contact between the metal clip and the rod is firm. If the contact is poor, arcing will occur after power is applied and the entire rod will be scrapped.
