Induction heating

[the middle]

it's the big fashion in Asia, to heat pieces of metal

I wonder how much it eats electricity to heat up so quickly.

The Just Hi!

It has existed for a long time in the industrial ovens of mines here in Quebec among others at the Horn foundry in Rouyn-Noranda.

Superb Lejuste Video

Indeed, we use this at work among other things to fret an aluminum alloy tube on a steel power shaft. (The aluminum tube expands enough to be able to cover the tree. On cooling it contracts and traps the tree with a force of X tonnes). Clean link without residual efforts poorly oriented, little metallurgical risk .... much better than press fitting in this case.

Given the face / design of the machine that does this, it is at least 30 or 40 years old. The work is very clean, 'without' danger of burns, energy efficient and with a minimum discharge of pollutants, gases, fumes oxides etc ... it automates very well

Yes Flytox!

It is used to enter and exit large ball bearings too.

Well, I didn't know.
In any case it is spectacular.

Magnetic aluminum tube?

My father's box (ACEC) already sold some in the 50s, notably to the main French car manufacturers.

It has been in use for ten years on high-end hobs: metal pans must be used.

Not metal !!! In metal FERRO MAGNETIQUE !!! Precision is important!

A copper pan will not heat any more than an aluminum or non-magnetic stainless steel ...

You need a conductive material so metal is fine ...

There is something that bothers me,
Ok, I have induction hobs at home, it's great,
But why do so many people show on youtube they know how to melt steel? (with little power)
Something is missing from me.
On the next link, it's 600w

Maybe it's a new induction process?
Ah! thank you Lietseu, fire fox offers to correct my French mistakes on the forum
