During use, the resistance value of silicon carbide rods gradually increases. When the resistance value reaches four times the initial resistance at the start of use, even if the rod remains intact, it is considered to have reached the end of its service life. U-shaped silicon carbide rods: Used in kilns requiring single-end wiring, commonly found in push-plate furnaces, car-bottom furnaces, box furnaces, and other periodic electric furnaces. Aging rods can cause a decrease in furnace temperature. To maintain normal furnace temperature, the operating voltage should be increased. If increasing the voltage to the maximum limit of the transformer still fails to meet requirements, the furnace can be shut down, and the wiring method of the rods can be modified before resuming operation. Therefore, frequently lowering the furnace temperature to room temperature will sharply increase resistance, leading to a shortened service life of the components.
