Excerpt from Iron and Steel: Their Sources, Varieties, Properties, and Manufacture, With Numerous Engravings and DiagramsCementation is a process in which a metal is made to take up a solid element, by being heated with it. In the metallurgy of Iron the principal example Is the carburising of malleable-iron, and the production of steel, by the prolonged exposure of the iron at a temperature below fusion, to the action of solid carbon. A similar action may go on in the blast furnace where the freshly reduced iron is in contact with the carbon of the fuel.Cold-short expresses a condition of iron or other metal in which when it is worked by hammering or rolling at or below a dull red-heat the edges crack or fracture according to the degree of the cold-shortness, perhaps such metal may be worked with the utmost facility at a higher temperature. Small quantities of phosphorus, silicon, arsenic, and antimony induce cold-shortness in iron or steel, phosphorus being the most common cause of this defect.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
