Common faults of box type annealing furnace

During the use of the box type annealing furnace, various common faults may be encountered. Here are some common faults and their possible causes and solutions:
1. Heating issue
Not heating up or heating up slowly
Possible reasons:
The heating element is damaged or aged.
Unstable power supply voltage or power line malfunction.
Excessive ash accumulation in the furnace affects heat transfer.
resolvent:
Check and replace damaged heating elements.
Check the power supply voltage and power lines to ensure normal power supply.
Regularly clean the accumulated ash and oxides in the furnace to maintain its cleanliness.
Large temperature fluctuations
Possible reasons:
Temperature control system malfunction or improper parameter settings.
The furnace has poor sealing and air leakage.
resolvent:
Check and repair the temperature control system, adjust the appropriate control parameters.
Check the sealing of the furnace and repair the air leakage points.
2. Mechanical malfunction
The furnace door is not tightly sealed
Possible reasons:
The sealing gasket of the furnace door is aging or damaged.
The furnace door is not tightly closed or adjusted properly.
resolvent:
Replace the gasket with a new one.
Adjust the closing position and force of the furnace door to ensure a tight seal.
Transmission mechanism malfunction
Possible reasons:
The transmission mechanism is worn or damaged.
Poor lubrication or lack of lubrication.
resolvent:
Check and replace worn transmission components.
Regularly add lubricating oil to maintain good lubrication of the transmission mechanism.
3. Electrical malfunction
Controller malfunction
Possible reasons:
The internal components of the controller are damaged or aged.
External interference causes abnormal operation of the controller.
resolvent:
Check and replace damaged controller components.
Eliminate external interference sources to ensure a good working environment for the controller.
Alarm system false alarm
Possible reasons:
Improper setting of alarm system parameters.
Sensor malfunction or damage.
resolvent:
Adjust the alarm system parameters to the appropriate range.
Check and replace damaged sensors.
4. Other faults
Gas leakage
Possible reasons:
Aging or damage of gas pipelines.
The gas valve is not tightly sealed.
resolvent:
Check and replace aging gas pipelines.
Repair or replace gas valves that are not tightly sealed.
Furnace cracking
Possible reasons:
The quality of furnace materials is unqualified.
The furnace works at high temperatures for a long time, generating thermal stress that leads to cracking.
resolvent:
Replace furnace materials with qualified quality.
Strengthen the cooling and insulation measures of the furnace to reduce the generation of thermal stress.
5. Prevention and maintenance
To prevent the occurrence of faults in the box type annealing furnace, the following measures can be taken:
Regular inspection: Regularly inspect and maintain various components of the annealing furnace to promptly identify and address potential issues.
Standardized operation: Operators should strictly follow the operating procedures to avoid equipment failure caused by misoperation.
Maintain cleanliness: Keep the furnace and equipment clean to prevent the accumulation of dust and oxides from affecting equipment performance.
Reasonable use: According to the design and usage requirements of the equipment, arrange production tasks and usage time reasonably to avoid overload operation and long-term continuous work.
