The usage method of sic heating element
1. SIC heater rod heated in the air, the surface of the dense silicon oxide film into a protective film of oxidation, play a role in extending life expectancy. Near several years, various coatings have been developed to prevent it from cracking and used in furnaces with various gases.
2. The larger the amount of current applied to the SIC rod, the higher its surface temperature. It is recommended to use as small a surface load density (power) as possible. Please note that the value recorded at the cold end is 1000 ℃ in the air current and voltage, which may not be the same with the actual use. In general, the surface power is obtained from the relationship between the furnace temperature and the surface temperature. It is recommended to use the surface power (W/cm2) of the limit density of 1/2-1/3
3. If continuously use, ought to that the slowly increase the resistance to maintain the long life
4. Keep in parallel as much as possible. If its resistance is different, the high resistance loads in series result in the rapid increase of one resistance and shortened life span.
If supporting with the automation power supply system, can get accurate constant temperature, but also according to the actual needs of the production process according to the curve automatically thermostat. It has been widely used in the fields of national defense, machinery, metallurgy, light-weight, ceramics, semiconductors, analytical laboratory, scientific research and other fields and has become the electric heating element of various electric furnace kilns. , muffle furnace, smelting furnace and all kinds of heating equipment, the use of silicon carbon rod heating is convenient, safe and reliable. It is widely used in electronics, magnetic materials, powder metallurgy, ceramics, glass, metallurgy and machinery industries such as a variety of high-temperature electric furnace, electric kiln, and its electric heating equipment.
Application of sic heating element: due to sic heater rod is used in high temperature, with high temperature, oxidation resistance, corrosion resistance, fast heating, long life, high temperature deformation, easy installation and maintenance and good chemical stability.
