What are the main points of maintenance of vacuum sintering furnace?

Vacuum sintering furnace is a kind of equipment used for sintering and heat treatment of metal materials, which is usually used for manufacturing materials such as powder metallurgy, metal ceramics and hard alloys. In order to ensure the normal operation of the vacuum sintering furnace and extend its service life, regular maintenance is required. So what are the main points of the vacuum sintering furnace maintenance? The following is a small summary of the medium frequency melting furnace vacuum sintering furnace maintenance of several major points:

1. Daily cleaning: regularly clean the inner surfaces of the furnace chamber and furnace door, etc., in order to remove the accumulation of dust, oxides and other impurities, and to prevent adverse effects on product quality. Cleaning should be selected with appropriate cleaning agents and tools to avoid damage to the furnace chamber and door.

2. Vacuum degree check: check whether the vacuum degree of vacuum sintering furnace is normal, to ensure that the vacuum degree required for sintering or heat treatment. You can use the vacuum measuring instrument to measure, if the vacuum degree is insufficient, you should check and exclude the reasons that may lead to vacuum degradation, such as aging seals, system leakage, etc..

3. Clean the cooling water circulation system: clean and maintain the cooling water system to keep the normal circulation and cooling effect of cooling water. Regularly check the cooling water supply and drainage system to avoid problems such as water pipe blockage, leakage or water pump failure.

4. Lubricate and maintain transmission parts: regularly check and lubricate the transmission parts of vacuum sintering furnace, such as motor, reducer, chain, etc., to keep them flexible and working properly. Meanwhile, check and adjust the tension of the transmission and the tightness of the chain to ensure its normal work and reduce wear and tear.

5. Check the electrical system and control system: regularly check the wiring and control board of the electrical system and control system to ensure their normal operation and avoid safety accidents caused by electrical faults. Particular attention needs to be paid to whether the power cord is old, the fuse is not damaged, and the control panel is not faulty.

6. Repair and Replacement of Furnace Lining: Regularly check the condition of the furnace lining, and repair or replace it in time when it is found to be cracked, broken or seriously worn. The integrity of the furnace chamber lining has an important impact on the uniformity of sintering and product quality.

7. Regular calibration of temperature control system: temperature control is an important part of the vacuum sintering furnace, regular calibration of the temperature control system to ensure its accuracy and reliability. Standard thermometers can be used for calibration, while paying attention to checking and adjusting the parameters and settings of the temperature control instrument.

8. Maintenance and repair of anti-corrosion coatings: Some vacuum sintering furnaces use anti-corrosion coatings on the internal metal surfaces to resist high temperatures and chemical corrosion. Periodically inspect and maintain the integrity and adhesion of the anti-corrosion coatings and repair or re-coat if necessary.

9. Regularly check the safety guards of the vacuum sintering furnace, such as door locks, emergency stops, exhaust systems, etc., to ensure their reliability and proper functioning to prevent accidents.

10. Make records and data analysis: maintenance should be recorded in a timely manner maintenance content, maintenance time and maintenance personnel and other information, and data analysis based on maintenance records to identify potential problems and improvement measures to improve the efficiency and reliability of the vacuum sintering furnace.

In summary, the main points of maintenance of vacuum sintering furnace include daily cleaning, vacuum check, cleaning of cooling water system, lubrication and maintenance of transmission parts, inspection of electrical system and control system, repair and replacement of furnace lining, calibration of temperature control system, maintenance and repair of anti-corrosion coatings, inspection of safety guards and records and data analysis. Through reasonable maintenance measures, you can ensure the normal operation of the vacuum sintering furnace and extend its service life.
