What is the reason why the temperature of the well crucible furnace cannot rise?

The inability to increase the temperature of a well crucible furnace may be caused by various reasons. The following are some common reasons and solutions:

1. Fuel or gas issues:
Low concentration of acidic gases or low calorific value of fuel gas can lead to incomplete combustion and insufficient heat. At this time, relevant personnel should be notified to ensure the concentration of acidic gases and the calorific value of fuel gas.
Low pressure of acidic gas or fuel gas, or malfunction of regulating valve, can affect the normal supply of gas. The gas pressure should be increased and the regulating valve should be repaired.
Blockage and incomplete combustion of the burner can also lead to insufficient heat. The burner needs to be cleaned to ensure sufficient combustion.
2. Process gas system issues:
The blockage of the process gas system pipeline and the obstruction of heat transfer will affect the temperature rise inside the furnace. Inspect the process gas pipeline, promptly address any blockages, and ensure smooth flow.
3. Instrument indication issues:
The malfunction of the instrument indication may result in the inability to accurately determine the temperature inside the furnace. The instrument needs to be inspected to ensure its normal operation.
4. Heating element issue:
Damage or aging of electric heating elements can lead to a decrease in heating efficiency. Check the working status of the electric heating element, and replace it promptly if it is damaged or aged.
5. Sealing problem of furnace:
Poor sealing of the furnace can cause heat loss and affect the temperature rise inside the furnace. The sealing of the furnace should be checked, and if there is any air leakage, it should be repaired in a timely manner.
6. Control system issues:
The temperature control system malfunction may result in the inability to accurately control the temperature inside the furnace. It is necessary to check the settings and working status of the temperature control system. If there are any abnormalities, they should be adjusted or repaired in a timely manner.
