Misunderstandings in The Use Of Carbon Rods And Methods Of Correct Use

In fact, many people use carbon rods incorrectly. Let’s take a look.

(1) The latest silicon carbide rods use various coatings, which are applied to the surface of the silicon carbide rods to prevent the cracking of the silicon carbide rods, so that they can be used in various gas furnaces, but this was not the case in the past. What can't be done, after the previous silicon carbide rods are heated in the air, a dense silicon oxide film is formed on the surface, which becomes an anti-oxidation protective film, which plays a role in extending the life.

(2) The silicon carbide rod manufacturer tells you that the surface temperature of the silicon carbide rod will be higher and higher as the current increases when the silicon carbide rod is in use. The silicon carbide rod manufacturer tells you that the surface power of the silicon carbide rod is caused by Obtained from the relationship between the temperature in the furnace and the surface temperature of the silicon carbide rod.

(3) When the silicon carbide rod is used again, we should slowly increase the resistance to extend the life.

(4) Silicon carbide rods should be connected in parallel as much as possible. If the resistance values of the silicon carbide rods are different, the load of the silicon carbide rods with high resistance is concentrated when connected in series, resulting in a rapid increase in the resistance of a certain silicon carbide rod and a shorter life span.
