recarburization Steel-making.|riːˌkɑːbjʊəraɪˈzeɪʃən|
[re- 5 c.]
Addition of carbon (in the form of coke, anthracite or a carbon-rich alloy such as pig iron) to steel to produce the desired composition after refining.
1888Jrnl. Iron & Steel Inst. 331 The recarburisation of the bath of iron gives rise, in the case of basic or neutral open hearth furnaces, to a very considerable loss of metal. 1924E. L. Rhead Metallurgy (ed. 3) xi. 222 Recarburisation is now often effected by the use of anthracite. This is put at the bottom of the ladle or thrown into the stream of metal as it runs from the furnace. 1940Simons & Gregory Steel Manuf. simply Explained xv. 105 Anthracite coal is used if the recarburization is carried out in the ladle.
Also reˈcarburize v. trans.; reˈcarburizing vbl. n.
1888Jrnl. Iron & Steel Inst. 332 This recarburising material consisted in the case of the first charge of 0·145 ton of ferro-manganese and 0·030 ton of ferro-silicon. 1929C. R. Hayward Outl. Metall. Pract. xxii. 475 Deoxidize and recarburize the bath. 1950Engineering 30 June 738/3 When making high-carbon steels..it was formerly common practice to run the carbon down in the furnace and then to recarburise to the composition required by the addition of coke or anthracite to the ladle. 1974Encycl. Brit. Macropædia XVII. 645/1 For a long time, high-carbon steels such as rails were made by recarburizing the steel with hot metal. 1974D. M. Considine Chem. & Process Technol. Encycl. 654/1 Deoxidizing, recarburizing, or alloying additions are made to the ladle during steel tapping from the furnace to adjust the final composition of the steel to the desired specification. |
