Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1902 edition. Excerpt: ... wrought iron in a layer of charcoal and subjecting them to a high temperature, or by exposing the surface of the iron to a current of carbnretted hydrogen gas at a high temperature. 23. Cast steel is made by melting bars of blister steel in a crucible along with a small quantity of carbon and some manganese, or it may be made by melting bars of pure malleable iron with manganese and the whole quantity of carbon required to make steel. 24. Granulated steel is made by running melted pig iron over a wheel into a cistern of water, the lumps being then taken out and embedded in pulverised hematite or in sparry iron ore, and exposed to a sufficient temperature to cause part of the oxygen of the ore to combine with and extract the carbon from the superficial layer of each of the lumps of iron, each of which is reduced to the condition of malleable iron at the surface while its heart continues in the state of cast iron. A small quantity of malleable iron is produced by the reduction of the ore. These ingredients being melted, produce steel. 25. Puddled steel is made by puddling pig iron and stopping the process at the instant when the proper quantity of carbon remains; the bloom is then shingled and rolled like bar iron. 26. Shear steel is made by breaking bars of blister steel into lengths, and making them up into bundles or fagots, and rolling them out at a welding heat, repeating the process until a near approach to uniformity of texture and composition is obtained. 27. The ultimate elongation of really good and tough specimens of iron and steel may be taken as follows: --In Bar iron, .. from-15 to-30. Plate iron, lengthwise -04 "17. crosswise 015 -11. Steel bars.. -05 -19. plates.....show more
