Steelmaking. Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur, and excess carbon (the most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon, and vanadium are added to produce ...
Forging a nail. Valašské muzeum v přírodě, Czech Republic. Forging is one of the oldest known metalworking processes. [1] Traditionally, forging was performed by a smith using hammer and anvil, though introducing water power to the production and working of iron in the 12th century allowed the use of large trip hammers or power hammers that increased the amount and size of iron that could ...

Water softening. Idealized image of water softening process involving replacement of calcium ions in water with sodium ions donated by a cation-exchange resin. Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is ...
In the back room (right) is a large pile of charcoal. A finery forge is a forge used to produce wrought iron from pig iron by decarburization in a process called "fining" which involved liquifying cast iron in a fining hearth and removing carbon from the molten cast iron through oxidation. [1] Finery forges were used as early as the 3rd century ...
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] It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores ...
But travel can be expensive. Kiplinger estimated that retirees spend anywhere from $10,000 to $50,000 on their yearly travel expenses. Even those who end up spending much less should still avoid ...
An Iron Forge develops the idea of blacksmith's shop which is a craft that has changed little on hundreds of years. Forges seen in the 1772 pension show the addition of water-powered hammers that allow the forger to stand proud before his family. The painting is in the Tate. A similar painting of a forge but viewed from outside is in the ...
