What are the maintenance points of high temperature graphitising furnace?

High temperature graphitising furnace is a kind of heating equipment commonly used in laboratory and industrial production. In order to ensure its normal operation and extend its service life, regular maintenance is required. The following are the main points of maintenance of high temperature graphitising furnace.

1. Cleaning maintenance:

   - Before and after using the furnace, the furnace must be thoroughly cleaned to remove dust, dirt and other impurities. Cleaning should be done with a soft cloth and can be cleaned with detergent and water.

   - The graphite boat inside the furnace should be cleaned periodically to remove accumulated residues and chemicals. Scrapers or other non-metallic tools can be used for cleaning.

   - Regularly check and clean the exhaust system to prevent the accumulation of dust and debris from affecting the exhaust effect.

2. Furnace body maintenance:

   - Regularly check the insulation of the furnace body for any damage or deformation to ensure temperature stability and safety. If it is damaged, it should be replaced in time.

   - Check and tighten the nuts and bolts connected to the furnace body to prevent loosening which may lead to deformation of the furnace body or unstable temperature.

   - Regularly check the sealing performance of the furnace body, if there is any leakage, the seal should be repaired or replaced in time.

3. Heating element maintenance:

   - Check and clean the dust and dirt on the surface of the heating element to ensure the heating effect and temperature uniformity. Brush or hair dryer can be used for cleaning.

   - Regularly check whether the connection between the heating coil and the core is loose, and tighten it in time if it is loose.

   - Regularly check the service life and wear and tear of the heating elements, and replace damaged elements if necessary.

4. Control system maintenance:

   - Regularly check whether the power lines and connections of the control system are normal to ensure the stability and safety of the circuit.

   - Check the accuracy and stability of temperature control instruments and controllers, and repair or replace them in time if there is any problem.

   - Regularly calibrate the accuracy of temperature control instruments and controllers to ensure the accuracy and stability of temperature control.

5. Other precautions:

   - The process of use should be in strict accordance with the requirements of the instruction manual to operate, avoid misoperation or overloading, so as not to damage the equipment.

   - When using the furnace, attention should be paid to safe operation, such as wearing heat-resistant gloves, goggles and other personal protective equipment to prevent accidents such as heat damage and chemical splashing into the eyes.

   - When the furnace is not in use for a long time, it should be disconnected and cleaned, and stored in a dry, ventilated place to prevent the equipment from aging and moisture and other problems caused by a long period of non-use.

Maintenance of high temperature graphitising furnace can be divided into several aspects such as cleaning and maintenance, furnace body maintenance, heating element maintenance, control system maintenance and other precautions. Through regular maintenance, can ensure the normal operation of high temperature graphitising furnace and extend the service life.
