What are the factors that affect the speed of medium frequency electric furnace?

How to adjust the speed of medium frequency electric furnace? First of all, we should start from the design of medium frequency electric furnace. In principle, the heating speed of medium frequency electric furnace is generally fixed, and the speed difference is not very big. The heating speed of the medium frequency electric furnace, that is, the heating speed is determined by the heating power of the medium frequency electric furnace, the material of the heating blank and the heating temperature. That is to say, after these factors are determined, the heating speed of the medium frequency electric furnace will be determined.

In principle, the heating speed of medium frequency electric furnace can’t be fast after it is manufactured, that is, under normal use, all kinds of heating parameters meet the design conditions of medium frequency electric furnace. The heating speed of medium frequency electric furnace can’t be fast, but can only be slow. In other words, it doesn’t exceed the rated power of medium frequency electric furnace, and the heating speed can be adjusted down at will.

In the normal use of medium frequency electric furnace, the factors that affect the power output of medium frequency electric furnace, and then affect the speed or heating speed of medium frequency electric furnace are as follows:

(1) The rectifier circuit of medium frequency electric furnace is not adjusted properly, the DC voltage does not reach the maximum value, the rectifier tube is not fully connected, and the DC voltage does not reach the rated value, which affects the power output;

(2) If the medium frequency voltage value of medium frequency electric furnace is adjusted too high or too low, the power output will be affected;

(3) If the current and voltage of medium frequency electric furnace are limited, the cut-off value is not adjusted properly, which makes the power output low; Adjusting the current limiting potentiometer of the control board of medium frequency electric furnace

(4) The medium frequency electric furnace body is not matched with the medium frequency power supply, which seriously affects the power output;

(5) If there are too many or too few compensation capacitors in the medium frequency electric furnace, the optimal power output of electricity rate and heat rate can not be obtained, that is, the optimal economic power output can not be obtained;

(6) If the distributed inductance of the output circuit and the additional inductance of the resonance circuit are too large, the maximum power output is also affected.
