| The process depended on the development of the blast furnace, of which medieval examples have been discovered at Lapphyttan, Sweden and in Germany. |
|
| While the bloomery process produced wrought iron directly from ore, cast iron or pig iron were the starting materials used in the finery forge and puddling furnace. |
|
| I'd played in the ruins of the Caerphilly furnace, and had cousins whose families had worked in both the Machen forges and the Melingriffith tinworks. |
|
| The cash is needed to reline a blast furnace at Newport's Llanwern plant. |
|
| Hot carbon dioxide, unreacted carbon monoxide, and nitrogen from the air pass up through the furnace as fresh feed material travels down into the reaction zone. |
|
| Variations of the blast furnace, such as the Swedish electric blast furnace, have been developed in countries which have no native coal resources. |
|
| The resultant heat was used to preheat the air blown into the furnace. |
|
| Cold restarts of a previously sintered furnace lining address a different set of issues than does the initial sinter, but the thermal issues are similar. |
|
| Darby's original blast furnace has been archaeologically excavated and can be seen in situ at Coalbrookdale, part of the Ironbridge Gorge Museums. |
|
| At Laskill, an outstation of Rievaulx Abbey and the only medieval blast furnace so far identified in Britain, the slag produced was low in iron content. |
|
| However, since blast furnace has also been invented independently in Africa by the Haya people, it is more likely the process has been invented in Scandinavia independently. |
|
| Recent evidence,shows that bloomeries were used in China, migrating in from the west as early as 800 BC, before being supplanted by the locally developed blast furnace. |
|
| The Chinese blast furnace remained in use well until the 20th century. |
|
|
|
| A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals and its alloys, generally iron, but also others such as lead or copper. |
|
| A slag hole, located higher up on the cylinder of the furnace, and usually to the rear or side of the tap hole, is opened to let the slag flow out. |
|
| In the US, the first use of coke in an iron furnace occurred around 1817 at Isaac Meason's Plumsock puddling furnace and rolling mill in Fayette County, Pennsylvania. |
|
| In 1687, while the lead cupola was out of their possession, Sir Clement and Talbot built a reverberatory furnace at Putney and smelted copper there. |
|
| In the early 1670s, Sir Clement joined various other people in sponsoring Dud Dudley to build a furnace at Dudley to smelt iron using a mixed fuel made from wood and coal. |
|
| The bonded, sand specimens were heated in a muffle furnace using a neutral atmosphere consisting of a 7 to 1 ratio of carbon dioxide and carbon monoxide. |
|
| Molten iron for this foundry work was not only produced from the blast furnaces, but also by remelting pig iron in air furnaces, a variant of the reverberatory furnace. |
|
| It was the location of the first blast furnace facility in North America. |
|
| From 1755 John Wilkinson became a partner in the Bersham concern and in 1757 with partners, he erected a blast furnace at Willey, near Broseley in Shropshire. |
|
| The process is similar to that of primary production in either a blast furnace or a rotary furnace, with the essential difference being the greater variability of yields. |
|
| Electric arc furnace steelmaking typically uses furnaces of capacity around 100 tonnes that produce steel every 40 to 50 minutes for further processing. |
|
| These projects included industrial plant relocation or closure, furnace replacement, introduction of new emission standards, and more strict traffic control. |
|
| Some examples of bath smelters include the Noranda furnace, the Isasmelt furnace, the Teniente reactor, the Vunyukov smelter and the SKS technology to name a few. |
|
| The precise details of the process will vary from one furnace to another depending on the mineralogy of the orebody from which the concentrate originates. |
|
| For this reason, a hearthless pusher-type furnace has been developed. |
|
| At the age of sixteen, boy it was hard yakka, pouring fifty ton of red hot molten gun metal from the big firebrick lined oil furnace almost every day of the working week. |
|
| The term 'founder' was applied in the British iron industry long afterwards to the ironworker in charge of the blast furnace and the smelting operation. |
|
| The pieces of iron obtained by cabbling are then heated in another furnace almost to fusion, hammered down into shape, and ultimately drawn out into bar-iron. |
|
| These metallic bodies gradually increasing in volume finally conglomerate into a larger mass, the bloom, which is extracted from the furnace with tongs. |
|
| Franklin also thought up the mid-room furnace known as the Franklin Stove. |
