7) SiC heating elements Features
1. Withstands as high as 1600°C (surface temperature)
2. Generates high heat output per unit surface area, approximately 5-10 times than
the output of Nichrome wire
3. High strength and excellent shock resistance
4. Heat source is free of noise and air pollution
8) Electric property of SIC heating element
silicon carbide heating elementshave rather large specific resistance.When it is heated in air and the surface temperature of the hot zone reaches 1050°C,it's resistance rate is 600-1400mm2/mm and its resistance value changes as the temperature rises which is negative value from room-temperature to 800 °C and is postive value nature over 800 °C
9) Advices
1)In order to keep furnace temperature and the charges uniform of each element, before installation resistance distribution must be carried.
2)As the element is very brittle ,be careful while install and maintain to avoid any damage.
3)when start to operate the furnace ,raise voltage slowly and gradually,never give full load at one time.
