HEARTH STEEL [9 records]

Record 1 2016-05-06

English

Subject field(s)
  • Steelmaking
CONT

Throughout the world, the basic oxygen furnace(BOF) produces more steel than any other process, and it is the primary steel production method in the United States. While the basic oxygen furnace is an improvement over the earlier open hearth and Bessemer processes, the vessel for converting pig iron into steel in a basic oxygen furnace is similar in design to its predecessor, the Bessemer converter. There is no heat source associated with the converter; it relies on the exothermic reaction between iron and oxygen. Therefore, a basic oxygen converter is not a furnace. However, there are some vessels that may use an additional hydrocarbon heat source.

OBS

basic oxygen furnace: term standardized by Environment Canada and the Translation Bureau for use in the Air Pollutant Emission Inventory Report.

French

Domaine(s)
  • Élaboration de l'acier
CONT

L'aciérie de Port Kembla qui utilise un convertisseur à oxygène transforme la ferraille et le fer liquide en acier brut, en utilisant de l'oxygène et des flux pour former le laitier. Après avoir prélevé des échantillons pour vérifier la température et la composition chimique, l'acier est coulé dans une poche de coulée réfractaire, et des alliages sont ajoutés pour produire la qualité d'acier requise.

OBS

convertisseur basique à oxygène : terme normalisé par Environnement Canada et le Bureau de la traduction dans le cadre de l'Inventaire des émissions de polluants atmosphériques.

Record 2 2016-02-29

English

Subject field(s)
  • Furnaces and Ovens (Metallurgy)
  • Processing of Mineral Products
DEF

A furnace, with a shallow hearth, usually non-regenerative, having a roof that deflects the flame and radiates heat toward the hearth or the surface of the charge. Firing may be with coal, pulverized coal, oil, or gas. Two of the most important types are the open-hearth steel furnaces and the large reverberatories employed in copper smelting.

Key term(s)
  • reverberatory refining furnace

French

Domaine(s)
  • Fours (Métallurgie)
  • Préparation des produits miniers
DEF

Four où la chaleur est produite par la combustion d'une matière solide ou liquide ou d'un mélange gazeux, donnant une flamme qui échauffe la charge en partie directement et en partie par l'intermédiaire de la voûte qui, portée à haute température, cède de la chaleur à la charge par rayonnement.

Record 4 2005-09-15

English

Subject field(s)
  • Steelmaking
DEF

Process of making steel by heating the metal in the hearth of a regenerative furnace.

OBS

In the basic open-hearth steel process, the lining of the hearth is basic, usually magnesite; whereas in the acid open-hearth steel process, an acid material, silica, is used as the furnace lining and pig iron, extremely low in phosphorous(less than 0. 04%), is the raw material charged in.

  • Élaboration de l'acier
DEF

Procédé de fabrication de l'acier, par affinage de la fonte dans un four à sole.

Record 5 2003-05-29

English

Subject field(s)
  • Steel
DEF

Steel produced in a furnace in which the hearth consists of a basic refractory such as dolomite or magnesite, as opposed to steel melted in a furnace with an acid lining.

OBS

The basic process permits the removal of sulphur and phosphorous and in this respect is superior. Present day BOS and electric arc furnaces use basic linings.
