Puddling (metallurgy)Puddling is the process of converting pig iron to bar (wrought) iron in a coal fired reverberatory furnace. It was developed in England during the 1780s. The molten pig iron was stirred in a reverberatory furnace, in an oxidizing environment to burn the carbon, resulting in wrought iron. It was one of the most important processes for making the first appreciable volumes of valuable and useful bar iron (malleable wrought iron) without the use of charcoal. Eventually, the furnace would be used to make small quantities of specialty steels.
IronbridgeIronbridge is a large village in the borough of Telford and Wrekin in Shropshire, England. Located on the bank of the River Severn, at the heart of the Ironbridge Gorge, it lies in the civil parish of The Gorge. Ironbridge developed beside, and takes its name from, The Iron Bridge, a cast iron bridge that was built in 1779. The area around Ironbridge is described by those promoting it as a tourist destination as the "Birthplace of the Industrial Revolution".
BirminghamBirmingham (ˈbɜːrmɪŋəm ) is a city and metropolitan borough in the metropolitan county of West Midlands in England. It is the second-largest city in the United Kingdom with a population of 1.145 million in the city proper, 2.92 million in the West Midlands metropolitan county, and approximately 4.3 million in the wider metropolitan area. It is the largest UK metropolitan area outside of London. Birmingham is commonly referred to as the second city of the United Kingdom.
Wrought ironWrought iron is an iron alloy with a very low carbon content (less than 0.05%) in contrast to that of cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to failure. Wrought iron is tough, malleable, ductile, corrosion resistant, and easily forge welded, but is more difficult to weld electrically.
Reverberatory furnaceA 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. Chemistry determines the optimum relationship between the fuel and the material, among other variables.
Cast ironCast 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.
KetleyKetley is a large village and part of Telford in the borough of Telford and Wrekin and ceremonial county of Shropshire, England. It is a civil parish. Immediately to the north of Ketley is Hadley. East Ketley is currently being re-developed as part of the Telford Millennium Community, part of the Millennium Communities Programme. It will consist of around 750 new homes and some live/work units, a new primary school, some small offices and retail and leisure services in a masterplan designed by Lifschutz Davidson Sandilands.
Blowing engineA blowing engine is a large stationary steam engine or internal combustion engine directly coupled to air pumping cylinders. They deliver a very large quantity of air at a pressure lower than an air compressor, but greater than a centrifugal fan. Blowing engines are majorly used to provide the air blast for furnaces, blast furnaces and other forms of smelter. The very first blowing engines were the blowing houses: bellows, driven by waterwheels.
HorsehayHorsehay is a suburban village on the western outskirts of Dawley, which, along with several other towns and villages, now forms part of the new town of Telford in Shropshire, England. Horsehay lies in the Dawley Hamlets parish, and on the northern edge of the Ironbridge Gorge area. Horsehay used to have four pubs, The Station Inn, The Forester Arms, the All Labour In Vain and the Travellers Joy, however The Station Inn closed down in 2012, and the All Labour In Vain closed in 2014.
Blast furnaceA 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 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.
