How to deal with the slow heating of the resistance furnace?

How to deal with the slow heating of the resistance furnace? A resistance furnace is a heating furnace that uses a resistance wire or a resistance strip as a heating element.
It is called a resistance furnace.
It has the characteristics of stable performance, easy maintenance, wide application range and high reliability
.

There are also some common faults in the use of resistance furnaces.
Let's introduce the fault analysis of temperature
.

1.
Slow heating up 1.
The power supply voltage is normal, the controller works normally, and the common fault is that some electric furnace wires are disconnected.
Check them with a multimeter and replace them with electric furnace wires of the same specification
.

2.
The power supply voltage is normal, but the working voltage of the electric furnace is low.
The reason is that the voltage drop of the power supply line is too large or the contact between the socket and the control switch is not good.
It can be adjusted and replaced
.

 　　3.
The power supply voltage is lower than the normal voltage, and the heating power of the electric furnace is insufficient when working
.

The three-phase power supply is out of phase, which can be adjusted and repaired
.

 　　2.
Abnormal temperature 1.
The thermocouple is not inserted into the furnace, causing the furnace temperature to be out of control
.

 　　2.
The graduation number of the thermocouple is inconsistent with the graduation number of the temperature control instrument, which will cause the furnace temperature to be inconsistent with the temperature displayed by the temperature control instrument.
After the resistance furnace fails in use, please power off immediately to check, and must not continue to work
.

 　　The above is the relevant introduction about the reasons for the slow heating of the resistance furnace.
I believe that everyone has a corresponding understanding of this after reading, and I hope it can help everyone
