List Of 19th-century Iron Smelting Operations In Australia
This is a list of 19th-century iron smelting operations in Australia. The earliest commercial iron ore smelting took place in 1848. There was an increase in pig iron prices in the early 1870s, which led to the formation of a number of colonial-era iron-making ventures in Australia. A world-wide shortage caused the price of imported pig-iron to increase, from £4 10s per ton in 1870 to £9 per ton in 1873 greatly advantaging locally manufactured iron. This period has been called, 'Australia's age of iron.' However, the high prices did not last long, as global iron-making capacity increased, and pig-iron was once again imported cheaply as ballast in sailing ships returning from England to Australia. After 1884, there was no commercial iron smelting in Australia, until William Sandford built a modern blast furnace at Lithgow in 1907. Trial smelting in foundries Trial smelting took place in foundries, typically using existing cupola furnaces usually used to melt iron to manufact ...

Pig Iron
Pig iron, also known as crude iron, is an intermediate product of the iron industry in the production of steel which is obtained by smelting iron ore in a blast furnace. Pig iron has a high carbon content, typically 3.8–4.7%, along with silica and other constituents of dross, which makes it brittle and not useful directly as a material except for limited applications. The traditional shape of the molds used for pig iron ingots is a branching structure formed in sand, with many individual ingots at right angles to a central channel or "runner", resembling a litter of piglets being nursed by a sow. When the metal had cooled and hardened, the smaller ingots (the "pigs") were simply broken from the runner (the "sow"), hence the name "pig iron". As pig iron is intended for remelting, the uneven size of the ingots and the inclusion of small amounts of sand cause only insignificant problems considering the ease of casting and handling them.

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] |
The Robertson Advocate
''The Robertson Advocate'' was an English language broadsheet newspaper published twice weekly, on Tuesdays and Fridays, in Mittagong, New South Wales, Australia. In 1924 the paper changed its name to ''The Robertson Mail''. History The paper is thought to have commenced publication some time before January 1888, and it continued under the same title until 28 December 1923. Beneath the title the banner reads: "Kangaloon, Wild's Meadow, Yarrunga, Kangaroo Valley Times". The last issue of the paper under its original title was Vol. 38 No. 101. The paper was subsequently published under the title of ''The Robertson Mail'' from January 1924 until 28 February 1930. At one time at least the ''Robertson Advocate'' was "printed and published for the proprietors by JOSEPH WHITE Offices — Mittagong, Bowral, Moss Vale and Robertson". Digitisation Both ''The Robertson Advocate'' and ''The Robertson Mail'' have been digitised as part of the Australian Newspapers Digitisation Progra ...

Lithgow Blast Furnace
The Lithgow Blast Furnace is a heritage-listed former blast furnace and now park and visitor attraction at Inch Street, Lithgow, City of Lithgow, New South Wales, Australia. It was built from 1906 to 1907 by William Sandford Limited. It is also known as Eskbank Ironworks Blast Furnace site; Industrial Archaeological Site. The property is owned by Lithgow City Council. It was added to the New South Wales State Heritage Register on 2 April 1999. History 1875 to 1900 Lithgow's association with its iron and steel works was another of this city's big manufacturing eras. Its iron and steel works commenced in October 1875 when the first iron smelting took place. Ore had been discovered by Dan Williams on Eskbank land which was then owned by Enoch Hughes, who had previously worked at the Fitzroy Iron Works at Mittagong. The foundry was erected nearby after Hughes convinced James Rutherford, of Cobb & Co. fame, from Bathurst to become involved. The other principal shareholders were t ...

Tamar Hematite Iron Company
The Tamar Hematite Iron Company (THIC) was an iron mining and smelting company that operated from April 1874 to December 1877, in the area close to the location of the modern-day township of Beaconsfield, Tasmania, Australia. The company's operations consisted of an iron ore mine near Brandy Creek, a blast furnace, jetty and township, on the Middle Arm of the estuary of the Tamar River, a tramway connecting the two sites, and charcoal and brick kilns. The THIC was the first company to produce iron in commercial quantities from Tasmanian ore and bring their product to market, although others had made small quantities earlier. It was the third company in Australia—at the time considered to be six separate self-governing British colonies—to make commercial quantities of pig-iron that was smelted from Australian iron ore. Pig-iron of good quality was made in its blast furnace from January 1875, until July 1875 when operations were suspended. Complicated by a decline in the pric ...

Blast Furnace
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. ''Blast'' refers to the combustion air being "forced" or supplied above atmospheric pressure. In a blast furnace, fuel ( coke), ores, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with oxygen enrichment) is blown into the lower section of the furnace through a series of pipes called tuyeres, so that the chemical reactions take place throughout the furnace as the material falls downward. The end products are usually molten metal and slag phases tapped from the bottom, and waste gases (flue gas) exiting from the top of the furnace. The downward flow of the ore along with the flux in contact with an upflow of hot, carbon monoxide-rich combustion gases is a countercurrent exchange and chemical reaction process. In contrast, air furnaces (such as reverbera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Empire (newspaper)
The ''Empire'' was a newspaper published in Sydney, Australia. It was published from 28 December 1850 to 14 February 1875, except for the period from 28 August 1858 to 23 May 1859, when publication was suspended. It was later absorbed by '' The Evening News''. History Henry Parkes founded the ''Empire'' and was its editor/proprietor until the business failed in August 1858. He made it "a newspaper destined to be the chief organ of mid-century liberalism and to serve as the rallying and reconciliation point for the sharpest radical and liberal minds of the day". The paper was bought by Samuel Bennett and William Hanson and resumed publication in May 1859 with the promise that "The Empire … will continue under the new management to advocate the same great principles by which it has hitherto been distinguished". In 1875 labour difficulties forced Bennett to merge the ''Empire'' with another of his papers, the ''Evening News''. ''The Evening News'' continued to be published unti ...

Reverberatory Furnace
A reverberatory furnace is a metallurgical or process furnace that isolates the material being processed from contact with the fuel, but not from contact with combustion gases. The term ''reverberation'' is used here in a generic sense of ''rebounding'' or '' reflecting'', not in the acoustic sense of ''echoing''. Operation Chemistry determines the optimum relationship between the fuel and the material, among other variables. The reverberatory furnace can be contrasted on the one hand with the blast furnace, in which fuel and material are mixed in a single chamber, and, on the other hand, with crucible, muffling, or retort furnaces, in which the subject material is isolated from the fuel and all of the products of combustion including gases and flying ash. There are, however, a great many furnace designs, and the terminology of metallurgy has not been very consistently defined, so it is difficult to categorically contradict other views.

Wrought Iron
Wrought iron is an iron alloy with a very low carbon content (less than 0.08%) in contrast to that of cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag Inclusion (mineral), inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to structural failure, failure. Wrought iron is tough, malleable, ductile, corrosion resistant, and easily forge welding, forge welded, but is more difficult to welding, weld electrically. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. It was given the name ''wrought'' because it was hammered, rolled, or otherwise worked while hot enough to expel molten slag. The modern functional equivalent of wrought iron is Carbon steel#Mild or low-carbon steel, mild steel, also called low-carbon steel. Neither wrought iron nor mild steel contain enough carbon to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tilt Hammer
A trip hammer, also known as a tilt hammer or helve hammer, is a massive powered hammer. Traditional uses of trip hammers include pounding, decorticating and polishing of grain in agriculture. In mining, trip hammers were used for crushing metal ores into small pieces, although a stamp mill was more usual for this. In finery forges they were used for drawing out blooms made from wrought iron into more workable bar iron. They were also used for fabricating various articles of wrought iron, latten (an early form of brass), steel and other metals. One or more trip hammers were set up in a forge, also known variously as a hammer mill, hammer forge or hammer works. The hammers were usually raised by a cam and then released to fall under the force of gravity. Historically, trip hammers were often powered hydraulically by a water wheel. Trip hammers are known to have been used in Imperial China since the Western Han dynasty. They also existed in the contemporary Greco-Roman world, wi ...
