A ladle refining furnace has the ability to reheat the liquid steel. This allows the steelmakers to add greater amounts of alloys to the liquid steel. The furnaces' ability to provide heat during refining by arc-reheating gives the steelmakers the capability to desulphurize, deoxidize and perform metallurgical operations with synthetic slag. 1, record 1, English, - ladle%20refining%20furnace

Smelting refers specifically to those high-temperature processes whereby ore and gangue minerals are chemically altered, fluxed and reduced to form a low-density molten slag and one or more heavier liquid metals or metallic compounds. 3, record 2, English, - smelting

When metallic ores are exposed to heat, and such reagents as develop the metal, it is called smelting in contradistinction from the mere application of heat, causing the ore to become fluid, which is called melting. 2, record 2, English, - smelting

Opération métallurgique qui permet d’obtenir un métal, un alliage ou un produit intermédiaire(matte), par passage partiel ou total à l'état liquide. Suivant la nature du composé réagissant, la fusion peut être réductrice, oxydante, carburante, sulfurante ou scorifiante. 3, record 2, French, - fusion
Record number: 2, Textual support number: 1 CONT
Dans les opérations de fusion, on obtient toujours au minimum trois phases : a) une phase ignée réduite, qui est le métal ou la matte, parfois un carbure, un siliciure, un arséniure (speiss), b) une phase oxydée qui est un laitier ou une scorie, rarement un sel fondu, c) une phase gazeuse, constituée principalement par les gaz de combustion (sauf dans le cas des fours électriques). 4, record 2, French, - fusion

Le terme «fusion» est employé aussi pour désigner la liquéfaction d’un métal sous le seul effet de chaleur, c’est-à-dire sans l’addition d’un réactif chimique; l’équivalent anglais dans ce cas est «melting». L’interprétation correcte du terme est déterminée à partir de son contexte. 5, record 2, French, - fusion

smelting: A metallurgical operation in which metal is separated by fusion from those impurities with which it may be chemically combined or physically mixed. The two most important types are reduction smelting, which produces molten metal and molten slag; and matte smelting which produces molten matte and molten slag. Smelting may be conducted in a blast furnace, a reverberatory furnace or an electric furnace. 2, record 3, English, - reduction%20smelting

[...] la fonte [s’obtient] aujourd’hui dans les hauts-fourneaux et dans les fours à cuve de fusion(creuset), par le traitement des minerais de fer, mélangés à un fondant au moyen du coke métallurgique. Les couches de minerai intercalées avec les couches de coke, chargées par la partie supérieure du fourneau, descendent peu à peu, s’échauffent, subissent des réactions chimiques complexes en présence des gaz chauds ascendants et fondent en arrivant dans la partie inférieure, où la température dépasse 1 800 °C. C'est la fusion réductrice. La fonte liquide et le laitier s’accumulent dans le creuset en deux couches superposées par ordre de densité, la fonte(la plus lourde) en bas, et sont évacués séparément par deux trous de coulée. 2, record 3, French, - fusion%20r%C3%A9ductrice
