  • 12 Riley, James

    SUBJECT AREA: Metallurgy
    [br]
    b. 1840 Halifax, England
    d. 15 July 1910 Harrogate, England
    [br]
    English steelmaker who promoted the manufacture of low-carbon bulk steel by the open-hearth process for tin plate and shipbuilding; pioneer of nickel steels.
    [br]
    After working as a millwright in Halifax, Riley found employment at the Ormesby Ironworks in Middlesbrough until, in 1869, he became manager of the Askam Ironworks in Cumberland. Three years later, in 1872, he was appointed Blast-furnace Manager at the pioneering Siemens Steel Company's works at Landore, near Swansea in South Wales. Using Spanish ore, he produced the manganese-rich iron (spiegeleisen) required as an additive to make satisfactory steel. Riley was promoted in 1874 to be General Manager at Landore, and he worked with William Siemens to develop the use of the latter's regenerative furnace for the production of open-hearth steel. He persuaded Welsh makers of tin plate to use sheets rolled from lowcarbon (mild) steel instead of from charcoal iron and, partly by publishing some test results, he was instrumental in influencing the Admiralty to build two naval vessels of mild steel, the Mercury and the Iris.
    In 1878 Riley moved north on his appointment as General Manager of the Steel Company of Scotland, a firm closely associated with Charles Tennant that was formed in 1872 to make steel by the Siemens process. Already by 1878, fourteen Siemens melting furnaces had been erected, and in that year 42,000 long tons of ingots were produced at the company's Hallside (Newton) Works, situated 8 km (5 miles) south-east of Glasgow. Under Riley's leadership, steelmaking in open-hearth furnaces was initiated at a second plant situated at Blochairn. Plates and sections for all aspects of shipbuilding, including boilers, formed the main products; the company also supplied the greater part of the steel for the Forth (Railway) Bridge. Riley was associated with technical modifications which improved the performance of steelmaking furnaces using Siemens's principles. He built a gasfired cupola for melting pig-iron, and constructed the first British "universal" plate mill using three-high rolls (Lauth mill).
    At the request of French interests, Riley investigated the properties of steels containing various proportions of nickel; the report that he read before the Iron and Steel Institute in 1889 successfully brought to the notice of potential users the greatly enhanced strength that nickel could impart and its ability to yield alloys possessing substantially lower corrodibility.
    The Steel Company of Scotland paid dividends in the years to 1890, but then came a lean period. In 1895, at the age of 54, Riley moved once more to another employer, becoming General Manager of the Glasgow Iron and Steel Company, which had just laid out a new steelmaking plant at Wishaw, 25 km (15 miles) south-east of Glasgow, where it already had blast furnaces. Still the technical innovator, in 1900 Riley presented an account of his experiences in introducing molten blast-furnace metal as feed for the open-hearth steel furnaces. In the early 1890s it was largely through Riley's efforts that a West of Scotland Board of Conciliation and Arbitration for the Manufactured Steel Trade came into being; he was its first Chairman and then its President.
    In 1899 James Riley resigned from his Scottish employment to move back to his native Yorkshire, where he became his own master by acquiring the small Richmond Ironworks situated at Stockton-on-Tees. Although Riley's 1900 account to the Iron and Steel Institute was the last of the many of which he was author, he continued to contribute to the discussion of papers written by others.

    SUBJECT AREA: Metallurgy
    [br]
    b. 1874 New York, USA
    d. 2 May 1921 Beacon, New York, USA
    [br]
    American metallurgist who gave his name to a successful nickel-copper alloy.
    [br]
    After graduating from Columbia University in 1896. Monell became a metallurgical engineer to the Carnegie Steel Company, rising in six years to be Assistant to the President. In 1900, while Manager of the company's open-hearth steelworks at Pittsburg, he patented a procedure for making high-carbon steel in basic conditions on the hearth of a fixed/stationary furnace; the method was intended to refine pig-iron containing substantial proportions of phosphorus and to do so relatively quickly. The process was introduced at the Homestead Works of the Carnegie Steel Company in February 1900, where it continued in use for some years. In April 1902 Monell was among those who launched the International Nickel Company of New Jersey in order to bring together a number of existing nickel interests; he became the new company's President. In 1904–5, members of the company's metallurgical staff produced an alloy of about 70 parts nickel and 30 copper which seemed to show great commercial promise on account of its high resistance to corrosion and its good appearance. Monell agreed to the suggestion that the new alloy should be given his name; for commercial reasons it was marketed as "Monel metal". In 1917, following the entry of the USA into the First World War, Monell was commissioned Colonel in the US Army (Aviation) for overseas service, relinquishing his presidency of the International Nickel Company but remaining as a director. At the time of his death he was also a director in several other companies in the USA.

    Monell insinuated an account of his steel-making procedure at a meeting of the Iron and Steel Institute held in London and reported in The Journal of the Iron and Steel
    Institute (1900) 1:71–80; some of the comments made by other speakers, particularly B.Talbot, were adverse. The following year (1901) Monell produced a general historical review: "A summary of development in open-hearth steel", Iron Trade

  • 16 Siemens, Sir Charles William

    [br]
    b. 4 April 1823 Lenthe, Germany
    d. 19 November 1883 London, England
    [br]
    German/British metallurgist and inventory pioneer of the regenerative principle and open-hearth steelmaking.
    [br]
    Born Carl Wilhelm, he attended craft schools in Lübeck and Magdeburg, followed by an intensive course in natural science at Göttingen as a pupil of Weber. At the age of 19 Siemens travelled to England and sold an electroplating process developed by his brother Werner Siemens to Richard Elkington, who was already established in the plating business. From 1843 to 1844 he obtained practical experience in the Magdeburg works of Count Stolburg. He settled in England in 1844 and later assumed British nationality, but maintained close contact with his brother Werner, who in 1847 had co-founded the firm Siemens \& Halske in Berlin to manufacture telegraphic equipment. William began to develop his regenerative principle of waste-heat recovery and in 1856 his brother Frederick (1826–1904) took out a British patent for heat regeneration, by which hot waste gases were passed through a honeycomb of fire-bricks. When they became hot, the gases were switched to a second mass of fire-bricks and incoming air and fuel gas were led through the hot bricks. By alternating the two gas flows, high temperatures could be reached and considerable fuel economies achieved. By 1861 the two brothers had incorporated producer gas fuel, made by gasifying low-grade coal.
    Heat regeneration was first applied in ironmaking by Cowper in 1857 for heating the air blast in blast furnaces. The first regenerative furnace was set up in Birmingham in 1860 for glassmaking. The first such furnace for making steel was developed in France by Pierre Martin and his father, Emile, in 1863. Siemens found British steelmakers reluctant to adopt the principle so in 1866 he rented a small works in Birmingham to develop his open-hearth steelmaking furnace, which he patented the following year. The process gradually made headway; as well as achieving high temperatures and saving fuel, it was slower than Bessemer's process, permitting greater control over the content of the steel. By 1900 the tonnage of open-hearth steel exceeded that produced by the Bessemer process.
    In 1872 Siemens played a major part in founding the Society of Telegraph Engineers (from which the Institution of Electrical Engineers evolved), serving as its first President. He became President for the second time in 1878. He built a cable works at Charlton, London, where the cable could be loaded directly into the holds of ships moored on the Thames. In 1873, together with William Froude, a British shipbuilder, he designed the Faraday, the first specialized vessel for Atlantic cable laying. The successful laying of a cable from Europe to the United States was completed in 1875, and a further five transatlantic cables were laid by the Faraday over the following decade.
    The Siemens factory in Charlton also supplied equipment for some of the earliest electric-lighting installations in London, including the British Museum in 1879 and the Savoy Theatre in 1882, the first theatre in Britain to be fully illuminated by electricity. The pioneer electric-tramway system of 1883 at Portrush, Northern Ireland, was an opportunity for the Siemens company to demonstrate its equipment.

    b. 1863 Middlesbrough, England
    d. 2 November 1934 Rotherham, Yorkshire
    [br]
    English chemist and metallurgist who introduced a treatment to remove sulphur from molten iron.
    [br]
    Saniter spent three years as a pupil in J.E.Stead's chemical laboratory in Middlesbrough, and then from 1883 was employed in the same town as Assistant Chemist at the new North-Eastern Steelworks. In 1890 he became Chief Chemist to the Wigan Coal and Iron Company in Lancashire. There he devised a desulphurizing treatment for molten iron and steel, based upon the presence of abundant lime together with calcium chloride. Between 1898 and 1904 he was in the Middlesbrough district once more, employed by Dorman Long \& Co. and Bell Brothers in experiments which led to the establishment of Teesside's first large-scale basic open-hearth steel plant. Calcium fluoride (fluorspar), mentioned in Saniter's 1892 patent, soon came to replace the calcium chloride; with this modification, his method retained wide applicability throughout the era of open-hearth steel. In 1904 Saniter became chief metallurgist to Steel, Peech \& Tozer Limited of Sheffield, and he remained in this post until 1928. Throughout the last forty years of his life he participated in the discussion of steelmaking developments and practices.
