How to adjust the heating speed of the intermediate frequency electric furnace

As a commonly used heating equipment, the intermediate frequency electric furnace has a problem that many users have to consider when using it. That is how to adjust the heating speed of the electric furnace.

In response to this problem, we have summarized some knowledge and experience here, and shared with you today.

From the analysis of the design of the electric furnace, the heating speed is determined by the heating power of the intermediate frequency furnace, the material of the heating blank and the heating temperature. After these factors are determined, the heating speed of the intermediate frequency furnace is also determined.

Therefore, theoretically speaking, the heating speed of the intermediate frequency furnace is fixed, and what will affect the heating speed of the electric furnace at this time is the power output of the electric furnace.

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

(1) The rectifier circuit part of the intermediate frequency furnace is not adjusted properly, the DC voltage does not reach the maximum value, the rectifier tube is not fully turned on, and the DC voltage does not reach the rated value, which affects the power output.

(2) The intermediate frequency voltage value of the intermediate frequency furnace is adjusted too high or too low, which affects the power output.

(3) The current and voltage limiting, current cutoff, and cutoff values of the intermediate frequency furnace are not adjusted properly, resulting in low power output. At this time, we need to adjust the current limiting potentiometer on the control board of the intermediate frequency furnace.

(4) The mismatch between the intermediate frequency furnace body and the intermediate frequency power supply will seriously affect the power output.

(5) Too many or too few compensation capacitors for the intermediate frequency furnace are configured, so that the furnace body cannot obtain the appropriate electric rate and heat rate during operation, and cannot achieve the best power output.

(6) The distributed inductance of the output circuit of the intermediate frequency furnace and the additional inductance of the resonant circuit are too large, which will also affect the power supply and affect the high-power output.

This is what we share today about adjusting the heating speed of the intermediate frequency furnace, I hope it can be helpful to you.
