üks induktsioonahjude liike, mida kasutatakse metallide (teras jt metallid) sulatuseks (vt induktsioonahi)
Good to know
Rauasulamite sulatamisel kasutatakse kõrgsagedusvoolu (üle 500Hz), mitterauasulamite sulatamisel madalama sagedusega (50Hz) voolu.
it is an essentially air transformer, in which the primary is a water cooled spiral of copper tubing, and the secondary the metal being melted (see: induction furnace)
Good to know
Currents at a frequency above about 500Hz are used to induce eddy currents in the charge, thereby setting up enough heat in the cause of melting; used in melting of steel and othet metals. Lower frequency (50Hz) is used for melting non-ferrous metals.
