Reasons for poor temperature uniformity of muffle furnace

1. The power distribution of juriya makera is unreasonable;

2. The electric heating element is open;

3. The unreasonable structure of the high-temperature electric furnace leads to excessive local heat dissipation;

4. The vacuum atmosphere furnace is poorly sealed, and the local heat dissipation is too large;

5. The gas circulation of the muffle furnace with fan is uneven or the wind is insufficient;

6. The thermocouple installation position or insertion depth cannot reflect the true temperature;

7. The electric heating elements of the resistance furnace are unreasonably distributed;

8. The bottom temperature of the thinking type electric furnace is low;

9. The heating power supply lacks phase and the fuse is broken;

auna:

1. Recalculate and improve the power configuration;

2. Replace the electric heating element of the open circuit;

3. Improve the structure of the high-temperature electric furnace or improve the cooling method;

4. Check the sealing of the vacuum atmosphere furnace to eliminate the bad factors of sealing;

5. Place the workpieces for the muffle furnace reasonably to increase the wind power of the fan;

6. Reasonably choose the installation position or insertion depth of the thermocouple;

7. Adjust the distribution of electric heating elements of the resistance furnace;

8. Increase the bottom heating power of the box-type electric furnace;
