Smelting is a process of applying heat and a chemical reducing agent to an ore to extract a desired base metal product. [1] It is a form of extractive metallurgy that is used to obtain many metals such as iron , copper , silver , tin , lead and zinc .
Bloomery smelting during the Middle Ages, as depicted in the De Re Metallica by Georgius Agricola, 1556. The onset of the Iron Age in most parts of the world coincides with the first widespread use of the bloomery. While earlier examples of iron are found, their high nickel content indicates that this is meteoric iron. Other early samples of ...
The tatara (鑪) is a traditional Japanese furnace used for smelting iron and steel. The word later also came to mean the entire building housing the furnace. The traditional steel in Japan comes from ironsand processed in a special way, called the tatara system. [1] Iron ore was used in the first steel manufacturing in Japan.
Bloomery smelting during the Middle Ages.. Ferrous metallurgy is the metallurgy of iron and its alloys.The earliest surviving prehistoric iron artifacts, from the 4th millennium BC in Egypt, [1] were made from meteoritic iron-nickel. [2]
Earlier processes for this included the finery forge, the puddling furnace, the Bessemer process, and the open hearth furnace. Modern steel mills and direct-reduction iron plants transfer the molten iron to a ladle for immediate use in the steel making furnaces or cast it into pigs on a pig-casting machine for reuse or resale. Modern pig ...
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 supplied above atmospheric pressure .
To create the pure iron necessary for forging, a smith must first purify the iron ore. The smelting of ore creates a "bloom", a porous mixture of slag and metal. The smith then repeatedly heats and hammers the bloom to remove impurities. This technique creates hammerscale of varying composition.
Whereas the earliest example of open-hearth steelmaking is found about 2000 years ago in the culture of the Haya people, in present day Tanzania, [3] and in Europe in the Catalan forge, invented in Spain in the 8th century, it is usual to confine the term to certain 19th-century and later steelmaking processes, thus excluding bloomeries ...
