Common faults and solutions of silicon carbide reaction sintering electric furnace
04-08-2025 Author: KJ technology
The silicon carbide reaction sintering electric furnace may encounter various common faults during operation. The following are these faults and their solutions:
1. Difficulty in raising temperature
Possible reasons:
Equipment malfunction and aging: damage to heating elements, malfunction of temperature controllers, etc.
Improper operation: setting the temperature too low, setting the heating rate unreasonably, etc.
Environmental factors: unstable power supply voltage, low external environmental temperature, etc.
resolvent:
Check the working status of the heating element and temperature controller, and replace them promptly if they are damaged.
Reasonably set operating parameters to ensure that the set temperature and heating rate meet the process requirements.
Ensure stable power supply voltage and avoid the impact of low external environmental temperature on furnace temperature rise.
2. Overtemperature alarm
Possible reasons:
Setting temperature too high: The operator mistakenly set a higher target temperature.
Temperature control system malfunction: temperature sensor damaged, temperature controller malfunctioning, etc.
Poor heat dissipation of the furnace body: Poor sealing of the furnace body, aging of insulation materials, etc.
resolvent:
Adjust the set temperature to a reasonable range.
Check and replace damaged temperature sensors or temperature controllers.
Improve the sealing of the furnace body and replace aging insulation materials.
3. Abnormal atmosphere control
Possible reasons:
Gas supply system malfunction: gas pipeline blockage, valve damage, etc.
Atmosphere control system malfunction: Atmosphere controller failure, sensor damage, etc.
Leakage of furnace body: Poor sealing of furnace door, damaged flange, etc.
resolvent:
Check and clear the gas pipeline, replace damaged valves.
Repair or replace the atmosphere controller and sensor.
Improve the sealing of the furnace door and replace damaged flanges.
4. Other common faults
Possible reasons:
Power failure: unplugged plug, blown fuse, etc.
Equipment component damage: such as thermocouple damage, heating element breakage, etc.
Improper operation: such as not following the operating procedures.
resolvent:
Check the power plug and fuse to ensure that the power supply is functioning properly.
Replace damaged equipment components.
Strengthen operator training to ensure that operations are carried out in accordance with operating procedures.
5. Comprehensive recommendations
Regularly maintain and upkeep the silicon carbide reaction sintering electric furnace to ensure that the equipment is in good condition.
Strengthen operator training to enhance their understanding of equipment performance and operating procedures.
Pay close attention to the operating status of the equipment during the operation process, promptly detect and handle abnormal situations.
