Railway and locomotive engineering : a practical journal of railway motive power and rolling stock . ortness isproduced by the phosphorus in themetal, it renders the material brittlewhen cold, and fit for nothing butmaking paper weights. The majority of the tonnage of steelto-day is furnished by the crucible,open-hearth and Bessemer steel is made by taking barsof wrought iron ,ind covering tliemover with charcoal or other carbona-ceous substance, they are then put inan air-tight crucible and subjected toan intense lieat until the bars are allcovered witli blisters. Tlicse l)ars are tlien taken out andmelted in a crucible. This is tlie very duction of the metal is obtained byusing the regenerative furnace in-vented by Siemens. This process ofmaking steel consists in first meltingcast iron on a layer of sand or mag-nesite, and then adding wrought ironto the melted cast iron; the flame thenbeing made to pass over the mixture,the action of the flame reducing thecarbon and silicon of the molten massand producing steel. The open-hearthiiutal is used most extensively; for. \I1£\V OF THE UP THE JUNGI-RSNOW-CAPPED finest steel made, but, on account of itsbeing very expensive, it is used only incertain parts of machines, fine tools,etc.; also for making razors and cut-lery. Of course it would be folly touse this steel for all parts of a ma-chine except for parts where great en-durance and sharp edges are and Bessemer processesproduce metal that gives satisfaction inmaking wearing parts of the open-hearth method the re- AU.

Bessemer steel(named after Sir Henry Bessemer, in-ventor of the process) is made by melt-ing cast iron and wrought junk in a fur-nace; after the material becomes meltedit is conveyed to a bottle-shaped con-verter, which is lin
