The influence to Rod surface in different Operating Temperature and Surface Load
| Atmosphere | Effect | Solution |
| Vapor and Moisture | 20%Service life shortened 20% than in dry air | New furnace or old furnaces notwork long time, to dry at low temperature completely and then heat up |
| Nitrogen gas | Above 1400C, nitrogen will react with SiC to form silicon nitride, elements will become fragile and service life shortened. Then effect by dew point is same as H2 | The recommended furnace temperature not higher than 1300C,surface loading as low as possible |
| Hydrogen | The mechanical strength decreasing when elements temperature exceeds 1350C, and also service life much depends on intensity of moisture | Operation temperature lower than1300C surface loading less than 5W/ CM2 |
| Ammonia | Same as hydrogen and nitrogen | Operation temperature lower than1300C, surface loading less than5W/ CM |
| Disassociated gas | Carbon black from decomposed hydrocarbon on elements surface will cause elements rod loose | Introducing air into furnace frequently to burn up additional Carbon. At side of furnace design,keep enough space between elements to prevent short circuit |
| S, S2 | Above 1300C, surface of elements will be corroded and resistance increasing rapidly | Keep elements temperature lower than 1300C |
| Vacuum | SiO2 protect film will not be formed, sic decomposed itself and service life shortened | Using in pressure over 0.13Pa an furnace temperature under 1100C |
| Others | Various substances from treated materials, such as Pb, Sb, alkali metal react with elements, which may shorten elements service life. | To get rid of these substances in advance, design gas outlet in furnace in order to decrease the effect. |
Installation and Operation
1. In order to keep the furnace temperature and the charges uniform of each element, resistance value must be matched first before installation, arrange those with close current values on the same circuit.
2. As the heating elements are made of ceramic, avoid damage from mechanical shock.
3. The diameter of a piercing hole drilled through the furnace should be about 1.5 times the diameter of element's end section. Size under 20mm is suitable for brick layers up to 150mm in thickness. Size under 25mm is suitable for brick layers up to 250mm in thickness.
When brick layers are thicker than the above thickness, widen the piercing hole diameter more 5mm.When SG type element is used, take 5mm more margin than the above value.
4. Silicon Carbide elements are electrically conductive. Care should be taken to avoid electric leakage due to direct contact with a conductive material or electric shock to a human body.
5. An equal length of element's cold zone should protrude out of the furnace. Elements should be installed so that the heating section( hot zone) does not intrude into the furnace wall. Install the elements at the center of the piercing hole, and lightly pack ceramic fibre around the element.
6. Make sure that neither the terminal clamp nor the terminal strap will contact the furnace wall directly. The terminal strap must have enough slack to give under finger pressure.
7. After completing connections, turn on electricity after lightly pressing the heating element with a finger tip and make sure it will move easily.
8. When replacing elements, it is recommended to replace all heating elements in the same circuit, otherwise the resistance difference new and old elements can cause a load imbalance. This imbalance results in the newer elements' loading being greater which could shorten its service lift. It is recommended that older, or " aged" elements be used on the same circuit.
9. When start to run the furnace, raise voltage slowly and gradually never give full load at one time, otherwise, the heating element will be damaged by over current impulse.
10. As the resistance of all silicon carbide elements increases during use a variable voltage power supply is usually provided. The power supply may consist of a step transformer, thyristor, or a combination of both. The type of equipment used may effect the element performance and therefore the necessary appliances shall be selected carefully.
11. Before use the new furnace or the furnace that has not been used for a long time, they must be dried. While drying, it better to use old elements or other heat source.
12. While sinter products or materials, if there is water ejection, the furnace should have holes to eject water vapor or other waste gases in order to protect the elements service life.
