Steel is heat treated using medium frequency induction heating power supply. How does it reduce energy consumption and save energy?

We all know that high energy consumption not only wastes resources, but also causes problems such as environmental pollution and increased carbon dioxide emissions. Therefore, saving energy, protecting the environment and reducing emissions has become an important task. The steel is heat-treated with a medium-frequency induction heating power supply, which can effectively reduce energy consumption. Today, the editor will tell you how to use medium frequency induction heating power for heat treatment of steel and how it saves energy.

1. Direct heating by induction current to reduce heat loss

Induction heating methods are different from traditional heating methods. Induction heating is the direct heating of the metal by the resistance heat transformed by the induced current generated inside the metal by an alternating power supply. The traditional heating method is to heat the metal through the radiation, convection and conduction of the high-temperature medium in the heating furnace. Therefore, in the process of heating metal, the heat loss of direct heating by induction current is lower than that of traditional furnace medium heating. This is one of the reasons why induction heating reduces heat loss and improves thermal efficiency.

2. The powerful heating capacity can realize rapid heating and save energy.

Induction heating provides powerful resistance heat energy to the metal being heated through the induction coil of the oscillation circuit. Usually unit volume of heat source space can provide 40-80MJ·cm-3·S-1 of heat energy, which is more than 100 times that of radiation and conduction heating in traditional oil and gas fuel furnaces. Therefore, the heating speed of the medium frequency induction heating power supply during induction heating can reach 100-200℃·S-1, and the heating coefficient of the steel can reach 1-5s.mm-1, achieving rapid temperature rise.

During the rapid heat treatment of steel by induction heating, by adjusting the power density applied to the surface heating of the steel, different heating rates and corresponding thermal efficiencies can be obtained, ultimately achieving the ideal heat treatment effect.

This article briefly introduces how the medium frequency induction heating power supply saves energy compared with other heating methods when performing induction heat treatment. In fact, the energy saving performance of medium frequency induction heating power supply is not limited to these. The editor will tell you about other things in my future life.
