H-type silicon carbide rod

After the rod passes through the rod holes on both sides (or up and down) of the furnace wall, it should rotate freely 360 degrees to prevent forced installation and knocking. Before installing the rod, an iron pipe with the same diameter as the rod can be used for trial installation.

The use of silicon carbide rods must be equipped with voltage regulators or controllable silicon voltage regulators, as well as voltage, current meters, and temperature automatic control instruments. During use, due to the oxidation of the rod, the resistance gradually increases. In order to maintain normal furnace temperature, the operating voltage should be increased. When the voltage reaches the maximum limit of the voltage regulator used but still cannot meet the requirements, the furnace can be stopped and the wiring method of the rod can be changed before continuing to use.
