Customized tube furnace daily maintenance

The daily maintenance of customized tube furnaces is a key step in ensuring their stable operation and extending their service life. Here are some suggestions for daily maintenance of customized tube furnaces:

1. Electrical system inspection
Regular inspection: It is necessary to regularly check whether the contact of each terminal of the equipment and controller is intact, and whether the pointer movement of the indicator is stuck. At the same time, use a potentiometer to check the scale error of the indicator to ensure that it does not exceed the normal range.
Working environment: The working environment temperature of the controller should be within 0-50 degrees Celsius to avoid damage to the equipment caused by excessively high or low temperatures. When transporting equipment, use wires to connect the “short” and “short” on the rear terminal block of the instrument to prevent damage to the instrument due to vibration.

2. Maintenance of furnace body and heating elements
Furnace body inspection: Regularly inspect the integrity of furnace body, furnace door, sealing device and other components to ensure that there is no damage or wear. For damaged components found, they should be replaced or repaired in a timely manner to prevent heat leakage or affect the temperature distribution inside the furnace.
Heating element cleaning: During use, the heating element will accumulate a certain amount of dust and impurities, which will affect the heating effect. Therefore, it is necessary to regularly clean the heating element to ensure that its surface is clean and free of dirt. At the same time, replace aging components in a timely manner based on their usage and lifespan.

3. Atmosphere control and cleaning
Atmosphere control: Pay attention to the control of the atmosphere inside the furnace, ensuring the uniformity and stability of the atmosphere to meet the needs of different process requirements. This helps to avoid the impact of atmospheric fluctuations on material handling or chemical reactions.
Cleaning the furnace: After each use, the furnace tube should be cleaned to avoid affecting the next use. The cleaning methods include physical cleaning and chemical cleaning. Physical cleaning uses mechanical force to break down the carbon residue accumulated in the pipeline, and then blows out the debris with high-speed airflow; Chemical cleaning is the process of destroying the structure of carbon slag or reacting with it through chemical reactions to achieve the purpose of slag removal. The selection of specific cleaning methods should be based on the actual situation.

4. Safe operation and training
Safe operation: During the maintenance process, attention should be paid to safe operation, strict adherence to safety operating procedures, and ensuring the safety of personnel and equipment.
Personnel training: Regularly train and assess maintenance personnel to improve their professional competence and operational skills, ensuring the quality and efficiency of maintenance work.
5. Other precautions
Avoid long-term idle: When the tube furnace is not in use for a long time, it should be regularly powered on for heating to prevent internal components from getting damp or damaged.
Regular maintenance: Generally, the maintenance cycle for customized tube furnaces is one year, which means that a major overhaul and maintenance should be carried out every year to ensure the long-term stable operation of the equipment.

In summary, the daily maintenance work of customized tube furnaces involves multiple aspects such as electrical system inspection, furnace body and heating element maintenance, atmosphere control and cleaning, safe operation and training, and other precautions. Only by taking scientifically effective measures for maintenance can the stable operation and extended service life of customized tube furnaces be ensured.
