Why are variable frequency induction heaters the core competence of induction furnaces?

In the field of industrial heating, more and more companies are starting to use induction furnaces to replace the traditional electrical resistance and gas heating. But when they do, many people face a new problem.

Why should I use a variable frequency induction heater when I use the same sensor heater?
Where is the variable frequency induction heater strong?

Some people say that variable frequency induction heaters are a punch line, while others don't understand why sales representatives say that variable frequency induction heaters are stable due to energy savings.

In fact, the variable frequency induction heater is not an additional function, but the core competitiveness of induction furnaces.

Here, I will explain little by little using the most understandable language.
What is a conversion? What did variable frequency induction heaters solve? Why does the performance fail without a variable frequency induction heater sensor?

First, understand one fundamental question: what is "frequency conversion"?

Don't talk about complex theories, just speak in human language.

1.What is the state without frequency conversion?

Most traditional heating equipment is:

Power on: Full power

Shutdown: Full stop

Just like driving with only:

Either press the accelerator pedal to the bottom

Either one foot will stop and kill

The result is:

high energy consumption

Big impact

Poor control

2.Frequency conversion , what does it mean?

Variable frequency=power can be adjusted at any time

Just like a car:

Start slowly and accelerate

uniform motion

Hurry up to the destination and slow down slowly

The same applies to induction heating furnaces:

We need to give more power quickly

Automatically reduce power as soon as approaching the target temperature

Maintain minimum energy consumption operation after temperature stabilization

Second, why should frequency conversion be combined with induction heating?

Key sentence:

Induction heating itself has a fast response, but without frequency conversion, it is easy to go too far.

The characteristics of induction heating are:

Heating up very quickly

Very responsive

If the power is not adjustable, the following will occur:

The temperature is rising too fast

Too late to control

High and low, repeatedly starting and stopping

The function of frequency conversion is to make this "fast" and "controllable".

Third, the first advantage of variable frequency induction heater: more power saving (it is also really saving)

Many customers are concerned about the following words.
Will the variable frequency induction heater really save electricity?

The reason is simple.
No conversion: always full power + down.
Frequency conversion: variable frequency induction heaters provide power as needed.

Let me give you a simple example.
Boil water in a pot.
No change: the fire has been at its maximum, stop when it boils.
Variable frequency induction heater: the fire is very big, close to the boiling point automatically adjust small.

The result is this:
It's more energy efficient.

In a real environment, variable frequency induction heater induction furnace:
On average, 15 to 30 percent.
The more complex the environment, the more energy saving becomes.

Fourth, second advantage: heating is more stable, engineering is better

For industrial users, stability is more important than 'speed'

Without frequency conversion, common issues include:

large temperature fluctuations

Poor product consistency

Poor repeatability of the process

And the variable frequency induction heating furnace can:

Real time adjustment of output power

Accurately control the heating rate

Long term constant temperature operation

This is particularly important for the following industries:

plastic machinery

Chemical heating

food processing

metal heat treatment

Summary in one sentence:

Frequency conversion determines the stability of heating.

Fifth, the third advantage: device-friendly, long life

The problem of non frequency conversion

High starting current

Strong impact on the power grid

Long term 'hard carrying' of electronic components

in the course of time:

Rapid aging of equipment

high failure rate

The benefits of frequency conversion

soft start

Smooth current

Low thermal shock

Not only good for the equipment, but also for:

Factory power grid

transformer

Other electrical equipment

More friendly.

Sixth, 4th benefit: smarter and more "hassle-free"

Nowadays, variable frequency induction heating furnaces can often achieve:

Automatic power adjustment

automatic constant temperature

Multi stage heating program

Linkage with PLC and automated production line

For users:

No need for frequent manual intervention

Not relying on 'master experience'

The system will 'calculate' itself

Seventh, why is it said that "the superiority of induction heating is weakened without variable frequency induction heaters"?

Summarize a very crucial sentence

Induction is' hard power ', while frequency conversion is' control power'.

No induction: efficiency is not improved

Without frequency conversion: control cannot keep up

What is truly useful is:

Variable frequency induction heating furnace, rather than a simple induction heating furnace.

Eighth, conclusion: variable frequency induction heaters are not optional, they are core competitiveness

With:

Rising energy costs

Improved process requirements

Improvement of automation level

What the market truly needs is no longer devices that can be heated, but rather:

Energy saving, stable, easy to control, durable, and intelligent heating system.

And these five points cannot be separated from "frequency conversion".

Frequency conversion is the core competitiveness that sets induction heating furnaces apart from traditional heating methods and widens the gap between them.
