high-frequency or ‘ironless’ induction furnaces
The frequency induction electric furnace has entered the world of industrial production from the laboratory of scientists, which has attracted wide attention.
It is true that induction cookers have been successfully applied in the commercial world for a long time, but these are all characterized by some form of iron core and operate at a relatively low frequency.
High probability though-
Schneider demonstrated frequency induction heating as early as 1905 and did not make much progress until 1919.
Notrap published an authoritative paper that reignited interest in the subject.
From this date, how fast is going, can be high from 1925
