SG Type SiC Heating element

Silicon carbon rods should be connected in parallel as much as possible. If the resistance values of silicon carbide rods are different, the high resistance silicon carbide rods in series will concentrate the load, causing a rapid increase in the resistance of one silicon carbide rod and a shorter lifespan
(1) The temperature distribution characteristics of silicon carbide rods are considered qualified only when the inspection specification for new shipments is within Δ 60 ℃ of the effective heating length. Of course, the temperature distribution will increase with aging and may eventually reach 200 ℃. The specific temperature distribution changes also vary depending on the furnace atmosphere and usage conditions.
(2) Silicon carbon rods have a shorter lifespan as the usage temperature increases. Therefore, after the furnace temperature exceeds 1400 ℃, the oxidation rate accelerates and the lifespan is shortened. During use, it is important to avoid excessively high surface temperatures on the silicon carbon rods.
