The following key points should be noted when installing and using a high-temperature tube furnace:
1. Preparation before use: First, ensure the power connection is normal and the voltage is within the specified range. Check that the furnace door can be opened and closed smoothly and that the furnace chamber is fully exposed.
2. Sample placement: Place the sample to be heated on the dedicated support inside the furnace chamber, ensuring full contact between the sample and the heat source, and secure it stably to prevent it from falling during heating.
3. Temperature setting: Set the heating temperature according to the experimental requirements, but do not exceed the maximum operating temperature of the equipment to avoid damage to the equipment or causing a fire.
4. Heating and heat preservation: Start the heating process. When the temperature reaches the set value, the equipment will automatically enter the heat preservation state. At this time, the heating button can be turned off to save energy.
5. Timing and cooling: Set the heating time according to the experimental requirements. The equipment will automatically stop heating after the predetermined time. After heating is complete, the equipment will automatically enter the cooling stage. Do not open the furnace door during this time to prevent cold air from entering and damaging the sample.
6. Sampling with the Door Opened: When the furnace temperature drops to a safe range, the furnace door can be opened to remove the sample. Carefully observe the sample for any abnormal changes, such as cracking or deformation.
7. Routine Maintenance: Regularly check the power connection, furnace door seal, and control system for proper functioning. Repair or replace any faulty parts promptly. After operation, turn off the power and clean the experimental area to ensure a clean and hygienic laboratory.
8. Precautions: During operation, laboratory safety regulations must be strictly followed to ensure personnel and environmental safety. Do not open the furnace door arbitrarily to avoid hot air escaping and causing burns or equipment damage. After heating, allow the equipment to cool naturally to a safe temperature before removing the sample to prevent burns or other safety issues caused by the high temperature.
