Silicon carbide rods are formed by high-temperature sintering using high-purity silicon carbide as raw material; The usage temperature of silicon carbon rods is generally not higher than 1400 degrees Celsius; Continuous service life up to 2000 hours; Silicon carbon rods, as non-metallic heating elements, have the advantages of high operating temperature, oxidation resistance, corrosion resistance, and long service life

Silicon carbide rod is a resistive electric heating element, and resistance plays a crucial role in the lifespan of the element. When ** a furnace, the resistance of the silicon carbide rod should be calculated based on the effective volume of the furnace, the temperature used, the number of elements, and the wiring method. When using, appropriate voltage regulating devices should be equipped based on the resistance of the silicon carbide rod. The initial voltage during power transmission should be half of its normal working voltage, and after stabilizing for a period of time, the voltage should be gradually increased. The resistance value of the silicon carbide rod varies with temperature. From a temperature range of around 800 ° C at room temperature, as the temperature rises, the resistance value of the rod increases; In the temperature range above approximately 800 ° C, as the temperature rises, the resistance value of the rod increases. Moreover, the dispersion of the resistance value of the rod at room temperature is relatively low. Therefore, the resistance value measured by a multimeter at room temperature is inaccurate and has no practical significance at room temperature. The resistance test and combination of silicon carbon rods should be based on the resistance value at high temperature (1050 ± 50 ℃).
