Abstract

L'INVENTION CONCERNE DES PERFECTIONNEMENTS AUX FOURS A CANAL A CHAUFFAGE PAR INDUCTION. LE FOUR COMPORTE UNE CUVE, DEUX CANAUX VERTICAUX, UN CANAL COLLECTEUR, UN INDUCTEUR DE CHAUFFAGE. IL COMPORTE EN OUTRE DES MOYENS 8 ADDITIONNELS CREANT UN CHAMP ELECTROMAGNETIQUE SUPPLEMENTAIRE ALTERNATIF, NON UNIFORME, DE FREQUENCE APPROPRIEE, DANS UNE ZONE LOCALISEE SPECIFIQUE, SELON UNE DIRECTION SPECIFIQUE ET UNE REPARTITION SPECIFIQUE. LA COOPERATION ENTRE LES CHAMPS ELECTROMAGNETIQUE PRINCIPAL ET SUPPLEMENTAIRE A POUR EFFET UNE CIRCULATION MODIFIEE DU METAL FONDU. APPLICABLE A DES FOURS A CANAL A CHAUFFAGE PAR INDUCTION.
