Best quality high temperature Elema/SiC Heater For muffle furnace use is a kind of non-metal high temperature electric heating element. it is made of selected super quality green silicon carbide as main material ,which is made into blank, silid under high temperature and re-crytallized. compared with metal electric heating elements, this elements is characterized by high-applied  temperature, anti-oxidization, anti-corrosion, long service life, little deformation ,easy installtion,long service life,little deformation,easy installation and maintenance. Therefore, it is widely used in various high temperature electric furnaces and other electric heating devices, such as in the industries of magent, ceramics, powder metallurgy ,glass, metallurgy and machinery etc.

Production and processing technology has reached the international leading level.

ATTENTION： When place the order of High Temperature Dumbbell SiC Heater For Industrial Furnace, pleas mark the below specifications: Model, the length of hotzone, the length of coldzone, the space between the middle of two shank.

Resistance and Surface Load:

Best quality high temperature Elema/SiC Heater For muffle furnace use  is inductive load.The resistance is not stable at room temperature,and vary along with increasing temperature.The characteristic curve is negative before 800℃,and positive above 800℃.So the correct resistance value should be tested at the temperature of 1050C.

Suitable surface load is the key to optimum longest service life.When to design the furnace ,please refer to the recommend surface load at different atmosphere

（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.
