3.Type of silicon carbide heater
about silicon carbide heater,we have rod,u,w,h,gun,single spiral,double spiral,dumbbell,door type.
4.Electric property of silicon carbide heater
Sic 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 .
The key factor to the optimum service life of the element is to select the surface load of the element correctly according to the furnace construction,atmosphere and temperature.The figure shows the relation between furnace temperatures,element temperature and element surface load under the condition that the element radiation is not obstructed.
5.Accessories of silicon carbide heaters
6.Advices of using silicon carbide heater
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.
