4.Heating elements
Working temperature | Heating elements | Characteristics |
W T≤1200C | Fe-Cr-Al-Mo wire | Compared with the ordinary iron chromium aluminum wire resistance, higher temperature and more durable |
W T≤1400C | SiC heater | Using high temperature, anti-oxidation, corrosion resistance, long life, small deformation, easy installation and maintenance. |
W T≤1750C | MoSi2 heater | Suitable for ultra high temperature heating, long service life, high calorific value and economic price |
5. Trouble shooting for typical Problems
Problems | Reason | Solution |
Open Power Lock, no power indication | Fuse (4A) in control panel is broken | Check control panel, and replace fuse |
Green Power indictor is off, but Red open circuit indicator is On | Fuse ( 50A) in main power circuit is broken | Open the cover of front panel and replace the fuse |
No current shows in meter , but has Max. Voltage | Heating element broken | Find broken heating rod, and replace it |
Controller display panel SV shows" OraL" | Thermal Couples broken | Replace Thermal couples ( B type ) |
Controller display panel SV shows" HI AL" | Furnace temperature > 1700C, Protection from Alarm | Cool furnace down, and find reason why temperature is so high ( program setting may be wrong) |
Power and heating element are OK, but furnace can't be controlled by program. | Controller or related circuit may be damaged | Heck controller. |
Program running, but furnace can not be heated, or real temperature is far behind the setting value | oPL or oPH value is too low due to local voltage lower or frenquency different | Incraese "oPL" and "oPH" value till current meter shows " 120 A - 140 A", and program runs smoothly |
During heating below 300C, the temperature value ( PV) is not stable, and doesn't match with setting program (SV) | It is normal because the furnace comes with a high temperature thermocouple, which is not sensitive at temperature below 300C | Don't worry. Let the furnace heat to 300C, then thermocouple will function stably with program. If the PV value at 300C is still less than that of SV, you may need to increase OPL value a little. |
