Transylvanian Mining Railway
The Transylvanian Mining Railway was a local interest narrow-gauge (760mm gauge) railway which was the first mining railway in Transylvania. This railway was built to ease the transportation of the iron ore mined from the iron ore mines from Ghelari to the blast furnace in Govăjdia and the ironworks from Hunedoara. This railway was also known as the "Hunedoara-Ghelari Local Interest Railway", "CFI Hunedoara", " Mocăniţa Hunedoara", "Calea Ferată Minieră Ardeleană", "Erdélyi Bányavasút" in Hungarian. The line was long from Hunedoara to Govăjdia and another from Govăjdia to Retişoara terminus. This line was used by mixed trains that carried both iron ore and passengers from Ghelari to Govăjdia and Hunedoara's ironworks. They also transported dolomite and limestone from the limestone quarries near Govăjdia to the ironworks. Line history Earlier the iron ore transport from the mines in Ghelari to the chutes and tipplers of the ironworks from Govăjdia was done by ho ...

Ironworks
An ironworks or iron works is an industrial plant where iron is smelted and where heavy iron and steel products are made. The term is both singular and plural, i.e. the singular of ''ironworks'' is ''ironworks''. Ironworks succeeded bloomeries when blast furnaces replaced former methods. An integrated ironworks in the 19th century usually included one or more blast furnaces and a number of puddling furnaces or a foundry with or without other kinds of ironworks. After the invention of the Bessemer process, converters became widespread, and the appellation steelworks replaced ironworks. The processes carried at ironworks are usually described as ferrous metallurgy, but the term siderurgy is also occasionally used. This is derived from the Greek words ''sideros'' - iron and ''ergon'' or ''ergos'' - work. This is an unusual term in English, and it is best regarded as an anglicisation of a term used in French, Spanish, and other Romance languages. Historically, it is comm ...

Ghelari Plan Inclinat Mina Principala
Ghelari ( hu, Gyalár) is a commune in Hunedoara County, Transylvania, Romania. It is composed of four villages: Ghelari, Govăjdia (''Govasdia''), Plop and Ruda. 2011 census results, Institutul Național de Statistică, accessed 20 February 2020. Govăjdia village is the site of the Govăjdia Blast Furnace. Natives * |
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 (fuel), coke), ores, and Flux (metallurgy), 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 #Process engineering and chemistry, 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 ...

Ropeway Conveyor
A material ropeway, ropeway conveyor (or aerial tramway in the US) is a subtype of gondola lift, from which containers for goods rather than passenger cars are suspended. Description Material ropeways are typically found around large mining concerns, and can be of considerable length. The COMILOG Cableway, which ran from Moanda in Gabon to Mbinda in the Republic of the Congo, was over in length. The Norsjö aerial tramway in Sweden had a length of . Conveyors can be powered by a wide variety of forms of energy, such as electricity, engines, or gravity (particularly in mountainous mining concerns, or where running water is available). Gravity-driven conveyors may qualify as zip-lines, as no electricity is used to operate them, instead relying on the weight of carts going down providing propulsion for empty carts going up. Double-rope (bi-cable) ropeways, have a carrying rope that supports the buckets and a separate hauling rope that controls their movement. Single-rope (mono-c ...

Funicular
A funicular (, , ) is a type of cable railway system that connects points along a railway track laid on a steep slope. The system is characterized by two counterbalanced carriages (also called cars or trains) permanently attached to opposite ends of a haulage cable, which is looped over a pulley at the upper end of the track. The result of such a configuration is that the two carriages move synchronously: as one ascends, the other descends at an equal speed. This feature distinguishes funiculars from inclined elevators, which have a single car that is hauled uphill. The term ''funicular'' derives from the Latin word , the diminutive of , meaning 'rope'. Operation In a funicular, both cars are permanently connected to the opposite ends of the same cable, known as a ''haul rope''; this haul rope runs through a system of pulleys at the upper end of the line. If the railway track is not perfectly straight, the cable is guided along the track using sheaves – unpowered pulleys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inclined Plane
An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle from the vertical direction, with one end higher than the other, used as an aid for raising or lowering a load. The inclined plane is one of the six classical simple machines defined by Renaissance scientists. Inclined planes are used to move heavy loads over vertical obstacles. Examples vary from a ramp used to load goods into a truck, to a person walking up a pedestrian ramp, to an automobile or railroad train climbing a grade. Moving an object up an inclined plane requires less force than lifting it straight up, at a cost of an increase in the distance moved. The mechanical advantage of an inclined plane, the factor by which the force is reduced, is equal to the ratio of the length of the sloped surface to the height it spans. Owing to conservation of energy, the same amount of mechanical energy ( work) is required to lift a given object by a given vertical distance, disregarding l ...

Govăjdia Blast Furnace
__NOTOC__ The Govăjdia Blast Furnace is a disused blast furnace in Govăjdia village, Ghelari Commune, Hunedoara County, in the Transylvania region of Romania. An earlier blast furnace had been set up at Toplița in 1781, but the quantity of raw materials it prepared for workshops involved in cast iron refining proved inadequate. Thus, the ''Thesaurariat'' at Sibiu, which represented the Imperial Austrian authorities, coordinated mining activities in Transylvania and had an office based in the Hunyad Castle, decided in 1802 to build a second furnace in the Hunedoara area. The site chosen was at the confluence of two rivers close to a group of forge works and iron mines. Ciprian Iancu"Furnalul de la Govăjdie, lăsat în paragină" ''Evenimentul Zilei'', 7 November 2010; accessed February 13, 2012 Construction began in 1806, and although finished in 1810, production only began in April 1813, once the necessary annexes had been built.
