Medium Frequency Induction Heating Furnace
Products Description
The Medium Frequency Induction Heating Furnace is used to heat spring steel bars before they are formed into hot coil springs. The equipment delivers heat directly to the material, allowing the steel bar to reach the required coiling temperature within a controlled heating period.
It is mainly used in production lines for automotive coil springs, truck suspension springs and other heavy-duty hot coiled springs. The heating system can be connected with an automatic feeding unit and hot coiling machine to support continuous production.
Working Principle
Spring steel bars are fed into the induction heating section at a controlled speed. The medium-frequency power supply generates an alternating electromagnetic field around the material, causing the steel itself to produce heat.
After reaching the required temperature, the heated bar is transferred to the coiling machine for forming. The operating parameters of the Medium Frequency Induction Heating Furnace can be adjusted according to the steel grade, bar diameter, heating length and production speed.
A typical system includes:
Medium-frequency power supply
Induction heating coils
Bar feeding and conveying system
Temperature monitoring device
Water cooling system
Electrical control cabinet
Key Advantages
Fast Material Heating
The Medium Frequency Induction Heating Furnace heats the spring steel directly, helping shorten the time between material loading and hot coiling.
Controlled Heating Temperature
The heating parameters can be matched with different spring steel specifications to maintain suitable forming conditions.
Easy Connection with Hot Coiling Equipment
The system can be arranged as part of a continuous line, allowing the heated steel bar to move directly to the coil spring forming machine.
Reduced Unnecessary Heat Loss
Unlike a large furnace chamber that must maintain an overall high temperature, induction heating concentrates energy on the material being processed.
Application
The Medium Frequency Induction Heating Furnace is mainly used for:
Automotive coil spring production
Truck suspension spring manufacturing
Heavy-duty vehicle coil springs
Commercial vehicle springs
Industrial hot coiled springs
Spring steel bar heating before hot forming
It is particularly suitable for production lines where the heating and coiling stages need to operate continuously.
