The reasons for the damage of silicon carbide rods may be in the following aspects: it will damage during transportation, handling, storage and installation. Generally, the silicon carbide rods mainly use a certain packaging form (usually a simple wooden packaging box) that is transported to the electrolytic aluminum factory by train or car for a long distance. In the process of installation and transportation, it will have collision or large vibration, which will directly damage the silicon carbon rod and scrap it. In addition, there will be crack on the surface of the silicon carbon rod these cracks will increase the resistance of the silicon carbon rod, thereby shortening its service life.
