FOUR ELECTRIQUE INDUCTION [6 records]

Record 1 2009-09-24

English

Subject field(s)
  • Electrochemistry
  • Electrometallurgy
CONT

An important industrial use of electrolysis is in the electrolytic furnace, which is employed in the manufacture of aluminum, magnesium, and sodium. In this furnace the resistance of a charge of metallic salts is used to heat the charge until it becomes molten and ionizes. The metal is then deposited electrolytically.

French

Domaine(s)
  • Électrochimie
  • Électrométallurgie
CONT

Parmi les fours électriques, on distingue le four à arc(la matière est fondue par un arc électrique jaillissant entre des électrodes), le four à résistance, le four à induction(le four lui-même constitue le secondaire d’une bobine d’induction), le four électrolytique(outre l'action thermique de l'électricité, il utilise le phénomène d’électrolyse).

Record 3 2007-05-16

English

Subject field(s)
  • Furnaces and Ovens (Metallurgy)
DEF

An electric melting furnace in which the primary conductor is coiled and generates, by electromagnetic induction, a secondary current which develops heat within the metal charge in the furnace.

French

Domaine(s)
  • Fours (Métallurgie)
DEF

Four électrique de fusion, dans lequel le conducteur primaire est bobiné et crée par induction électromagnétique un courant secondaire qui apporte de la chaleur à la charge de métal se trouvant dans le four.

Record 4 2004-01-05

English

Subject field(s)
  • Electrometallurgy
DEF

An alternating current electric furnace in which the primary conductor is coiled and generates, by electromagnetic induction, a secondary current that develops heat within the metal charge.

CONT

There are two classifications of induction furnaces: coreless and channel. In a coreless furnace, the refractory-lined crucible is completely surrounded by a water-cooled copper coil, while in the channel furnace the coil surrounds only a small appendage of the unit, called an inductor. The term "channel" refers to the channel that the molten metal forms as a loop within the inductor. It is the metal loop that forms the secondary of the electrical circuit, with the surrounding copper coil being the primary. In a coreless furnace, the entire metal content of the crucible is the secondary.

PHR

Channel type, high-frequency electric, low-frequency electric induction furnace.

French

Domaine(s)
  • Électrométallurgie
CONT

Les fours électriques proprement dits se divisent en quatre types : le four à arc [...]; le four à résistance [...]; le four à induction, où la masse du four constitue le secondaire d’une bobine d’induction, qui agit comme un véritable transformateur [...]; les fours à micro-ondes [...]

PHR

Four électrique à induction à canal, à basse fréquence, à haute fréquence.

English

Subject field(s)
  • Foundry Practice
DEF

An electric induction furnace for melting or holding molten metals that does not utilize a steel core to direct the magnetic field which stirs the melt.

CONT

The steel industry uses two types of induction electric-furnaces. These are the "channel" and "coreless" types.
