Definition of deoxidize in English:

deoxidize

(British deoxidise)
verb diːˈɒksɪdʌɪzdiˈɑksəˌdaɪz
[with object]
  • Remove combined oxygen from (a substance, usually a metal)

    使(金属等)脱氧

    the melt is deoxidized with ferrosilicon or aluminium
    Example sentencesExamples
    • When the molten metal reaches 1260 o C, either calcium boride or lithium should be plunged into the molten bath to deoxidize the melt.
    • A second limey slag is used to remove sulphur and to deoxidise the metal in the furnace.
    • When the cast electrodes of air-melted steel are remelted under vacuum and deoxidized with carbon, the product has significantly improved purity.
    • Aluminum, on the other hand, not only deoxidizes the steel, but also refines the grain size.

Derivatives

  • deoxidation

  • noun diːˌɒksɪˈdeɪʃ(ə)ndiˌɑksəˈdeɪʃən
    • These steels are not deliberately strengthened by alloying elements other than carbon; they contain some manganese for sulfur stabilization and silicon for deoxidation.
      Example sentencesExamples
      • Carbon steel can be classified, according to various deoxidation practices, as rimmed, capped, semi-killed, or killed steel.
      • For deoxidation of carbon and low-alloy steels, aluminum, titanium, and zirconium are used.
      • In a vacuum furnace, carbon is an excellent deoxidizer, and the deoxidation product, carbon monoxide gas, is continuously removed under vacuum.
      • In some foundries in which combustion cannot be properly controlled, oxidizing fluxes are added during melting, followed by final deoxidation by phosphor copper.
  • deoxidizer

  • noun
    • Most commercial steels contain about 0.5% manganese to serve as a deoxidizer and to tie up sulfur as manganese sulfide, thereby preventing the occurrence of hot-cracking.
      Example sentencesExamples
      • Aluminum is widely used as a deoxidizer and was the first element used to control austenite grain growth during reheating.
      • In tin bronze, phosphorus has traditionally been the deoxidizer, hence the name ‘phosphor bronzes’ for these alloys.
      • In steels of this type, silicon is added as the deoxidizer followed by the addition of aluminum for grain size control.
      • In a vacuum furnace, carbon is an excellent deoxidizer, and the deoxidation product, carbon monoxide gas, is continuously removed under vacuum.
