British And Tasmanian Charcoal Iron Company
The British and Tasmanian Charcoal Iron Company (BTCIC) was an iron mining and smelting company that operated from 1874 to 1878 in Northern Tasmania, Australia. It was formed by floating the operations of a private company, the Tasmanian Charcoal Iron Company that operated between 1871 and 1874. This venture was the largest of the four that smelted iron from local iron ore in Tasmania during the 1870s. Despite its name, the company was mainly owned by shareholders from the colonies of Victoria and Tasmania, and it used coke rather than charcoal. The company's operations included an iron ore mine near Anderson's Creek and a railway from the mine to its blast furnace and port near Redbill Point—now part of modern-day Beauty Point—on the West Arm of the Tamar River estuary in Northern Tasmania. Its blast furnace—the largest and most modern in Australia for its time—produced pig-iron June 1876 to August 1877. Both well-capitalised and well-managed, the BTCIC used well-des ...

Cleveland Ironstone Formation
The Cleveland Ironstone Formation is a sequence of marine ironstone seams interbedded with shale and siltstone units which collectively form a part of the Lower Jurassic System of rocks underlying Cleveland in North Yorkshire. Exploitation of the ironstone seams became a major driving force behind the industrialisation of the Teesside district during the mid- to late-1800s. Based on the stratigraphy of the formation, the Cleveland Ironstone was found to belong within the Upper Pliensbachian (Domerian) universal stage. Ironstone seams and accompanying shales may be highly fossiliferous with remains so abundant in parts as to form well-developed shell-beds. Analysis reveals a wealth of shallow-water marine species, some in life position, along with trace fossils including '' Rhizocorallium'' burrows well exposed at Old Nab, east of Staithes. Stratigraphy Formerly classified as part of the Middle Lias, these strata were deposited over a period of about 2 million years, as soft ...

Grey Cast Iron
Gray iron, or grey cast iron, is a type of cast iron that has a graphitic microstructure. It is named after the gray color of the fracture it forms, which is due to the presence of graphite.. It is the most common cast iron and the most widely used cast material based on weight.. It is used for housings where the stiffness of the component is more important than its tensile strength, such as internal combustion engine cylinder blocks, pump housings, valve bodies, electrical boxes, and decorative castings. Grey cast iron's high thermal conductivity and specific heat capacity are often exploited to make cast iron cookware and disc brake rotors. Its former widespread use on brakes in freight trains has been greatly reduced in the European Union over concerns regarding noise pollution. Deutsche Bahn for example had replaced grey iron brakes on 53,000 of its freight cars (85% of their fleet) with newer, quieter models by 2019—in part to comply with a law that came into fo ...

Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...

Spiegeleisen
Spiegeleisen (literally "mirror-iron", —mirror or specular; —iron) is a ferromanganese alloy containing approximately 15% manganese and small quantities of carbon and silicon. Spiegeleisen is sometimes also referred to as ''specular pig iron'', ''Spiegel iron'', just ''Spiegel'', or ''Bisalloy''. Usage Historically, this was the standard form in which manganese was traded and used in steel making. Manganese is useful in steel manufacture because it binds with phosphorus, sulfur, and silica, removing them (to a degree) from the iron. It was much used in conjunction with the Bessemer process both to introduce carbon and manganese, and also to reduce impurities. Manufacture In the 19th-century spiegeleisen was made either by mixing iron ores with appropriate levels of manganese and smelting them directly, or by adding pyrolusite or manganite to previously smelted iron in a cupellation furnace. Today, manganese is usually traded and used in more concentrated form, 80% mangane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coke (fuel)
Coke is a grey, hard, and porous coal-based fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern. The unqualified term "coke" usually refers to the product derived from low-ash and low-sulphur bituminous coal by a process called coking. A similar product called petroleum coke, or pet coke, is obtained from crude oil in oil refineries. Coke may also be formed naturally by geologic processes.B. Kwiecińska and H. I. Petersen (2004): "Graphite, semi-graphite, natural coke, and natural char classification — ICCP system". ''International Journal of Coal Geology'', volume 57, issue 2, pages 99-116. History China Historical sources dating to the 4th century describe the production of coke in ancient China. The Chinese first used coke for heating ...

Bulli Jetty, Sandon Point, New South Wales
Bulli Jetty at Sandon Point, was first built in 1863 and was abandoned in 1943. During that time it was used by the Bulli Coal Company in the transportation of coal from the Bulli mine to the ships for export to other destinations. D. H. Lawrence who visited Thirroul in 1922 and lived only about 900 meters from the jetty described it as, a long, high jetty straddling on great tree-trunk poles out on to the sea, and carrying a long line of little red-coal trucks, the sort that can be tipped up…As a rule the jetty was as deserted as if it were some relic left by an old invader. Then it had spurts of activity, when steamer after steamer came blorting and hanging miserably round, like cows to the cowshed on a winter afternoon. Then a little engine would chuff along the pier, shoving a string of tip-up trucks, and little men would saunter across the sky-line, and there would be a fine dimness of black dust round the low, red ship at the end of the jetty. History The line was orig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frederick Weld
Sir Frederick Aloysius Weld (9 May 1823 – 20 July 1891), was a New Zealand politician and a governor of various British colonies. He was the sixth premier of New Zealand, and later served as Governor of Western Australia, Governor of Tasmania, and Governor of the Straits Settlements. Early life Weld was born near Bridport, Dorset, England, on 9 May 1823. His mother, Christina Maria Clifford, was the daughter of Baron Clifford of Chudleigh. Both of his parents were from old recusant Catholic families. His father, Humphrey Weld of Chideock, was a member of the Weld family. Humphrey's father Thomas Weld (of Lulworth) donated the land and endowed the Jesuit college at Stonyhurst. Weld's upbringing was strongly grounded in the Catholic faith. His early years were spent with his parents in France. Later, he received a good education, studying at Stonyhurst before attending a predecessor of the University of Fribourg in Switzerland, where he studied philosophy, chemistry, language ...

Bessemer Converter
The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten. Related decarburizing with air processes had been used outside Europe for hundreds of years, but not on an industrial scale. One such process (similar to puddling) was known in the 11th century in East Asia, where the scholar Shen Kuo of that era described its use in the Chinese iron and steel industry. In the 17th century, accounts by European travelers detailed its possible use by the Japanese. The modern process is named after its inventor, the Englishman Henry Bessemer, who took out a patent on the process in 1856. The process was said to be independently discovered in 1851 by the American inventor William Kelly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sponge Iron
Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. Reduced iron derives its name from these processes, one example being heating iron ore in a furnace at a high temperature of in the presence of the reducing gas syngas, a mixture of hydrogen and carbon monoxide. Process Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below ). The dire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Charles Du Cane
Sir Charles Du Cane (5 December 1825 – 25 February 1889) was a British Conservative Party politician and colonial administrator who was a Member of Parliament between 1852 and 1854 and Governor of Tasmania from 1868 to 1874. Du Cane was born in Ryde on the Isle of Wight in 1825, the son of Charles Du Cane of Braxted Park and Frances Prideaux-Brune. He was educated at Charterhouse School in Surrey and Exeter College, Oxford. From 1848 to 1855, Du Cane played first-class cricket for the Marylebone Cricket Club as a batsman; a younger brother, Alfred, also played first-class cricket. In 1852, he was elected to the House of Commons as a Member of Parliament (MP) for Maldon in Essex, but his election was declared void after it was discovered that Du Cane's agents had been involved in bribery although it was established that Du Cane was unaware of the corruption. He spent two years as Civil Lord of the Admiralty. At the 1857 general election he was elected as MP for Northern Ess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
