The inability to increase the temperature of the silicon carbide reaction sintering electric furnace may be caused by various reasons. The following are some common reasons and their analysis:

Power issue:

Insufficient or unstable power supply voltage may result in insufficient heating power, affecting the heating rate.

Solution: Check if the power supply voltage is stable and use a voltage regulator to ensure that the voltage is within the normal range.

Heating element issue:

Heating elements (such as silicon carbon rods, silicon molybdenum rods, etc.) that are aging, damaged, or have poor contact may lead to a decrease in heating efficiency.

Solution: Check the working status of the heating element. If there is any damage or poor contact, replace or repair it in a timely manner.

Temperature control system issue:

Incorrect temperature setting or malfunction of the temperature controller may result in the temperature not reaching the expected value.

Solution: Check the temperature setting value to ensure that the temperature controller is working properly. If there is a malfunction, repair or replace it promptly.

Furnace structure and insulation issues:

Poor sealing of the furnace body or aging of insulation materials may cause heat loss, affecting the heating effect.

Solution: Check the sealing and insulation material status of the furnace body. If there is any damage or aging, replace the sealing components or insulation materials in a timely manner.

Atmosphere control issues:

If cooling gases (such as nitrogen, argon, etc.) are introduced into the furnace and the gas flow rate is too high, it may carry away too much heat, causing the temperature to not rise.

Solution: Adjust the gas flow rate to ensure that the atmosphere control meets the requirements of the sintering process.

Load issue:

Excessive load inside the furnace or poor thermal conductivity of the load may also slow down the heating rate.

Solution: Optimize the placement of the load, reduce the load or improve the thermal conductivity of the load.
