Note for use:
1.Best quality high temperature Elema/SiC Heater For muffle furnace use is heated in the air after the formation of a silicon oxide film compact surface,Into a protective film to protect the antioxidant, play a role in prolonging life. In recent years, our company developed a variety of silicon carbide coating to prevent cracking, for a variety of gas furnace.
2.To the current amount of silicon carbide with larger surface temperature of silicon carbide is higher. Recommended to use as much as possible a small surface load density (power). Please note that the value of silicon carbide cold end recorded as current and voltage in the air temperature of 1000 DEG C, and may not be consistent with the actual use. Under normal circumstances, silicon carbide surface power is obtained by the relationship between the furnace temperature and silicon carbide surface temperature, recommend the use of silicon carbide density limit of current, voltage, and actual use is not necessarily match. Under normal circumstances, the surface of silicon carbide power is obtained by the relationship between the furnace temperature and silicon carbide surface temperature, recommend the use of silicon carbide density limit of 1 / 2-1 / 3 numerical surface power (w / cm2)
3.Continuous use of silicon carbide, hoping to slow increasing resistance to maintain long life.
4.Global as far as possible in parallel. If the silicon carbide with different resistance and series resistance of silicon carbide rod load, resulting in a rapid increase in a silicon carbide rod resistance, shorter life expectancy.
5.High Temperature Dumbbell SiC Heater For Industrial Furnace temperature distribution characteristics in the effective heating length is less than delta 60 DEG C to qualify new shipment inspection specifications to and of course temperature distribution will with aging while the larger, may eventually reach 200 DEG C. The specific temperature distribution is also different due to the different atmosphere and conditions of use. The specific temperature distribution is also different due to the different atmosphere and conditions of use.
6.After the silicon carbide rod with the temperature higher lifetime is shorter, so in the furnace temperature super 1400 DEG C, accelerate the oxidation rate, shorten life. Use note try not to let the silicon carbide surface temperature is too high.
