Steel is made from iron and carbon. Cast iron is a hard, brittle material that is difficult to work, whereas steel is malleable, relatively easily formed and versatile. On its own, iron is not strong, but a low concentration of carbon – less than 1 percent, depending on the kind of steel – gives steel strength and other important properties.
Although the outpost was one of the most remote from Jamestown, beginning in 1619, the Falling Creek Ironworks was established there. It was the first iron production facility in North America. [3] Records which have survived indicate that the ironworks was able to produce some quantity of iron.
Iron and copper working spread southward through the continent, reaching the Cape around AD 200. [6] [7] The widespread use of iron revolutionized the Bantu-speaking farming communities who adopted it, driving out and absorbing the rock tool using hunter-gatherer societies they encountered as they expanded to farm wider areas of savanna. The ...
A plough or plow (both pronounced / p l aʊ /) is a farm tool for loosening or turning the soil before sowing seed or planting. [1] Ploughs were traditionally drawn by oxen and horses but modern ploughs are drawn by tractors. A plough may have a wooden, iron or steel frame with a blade attached to cut and loosen the soil.
Onekaka Iron and Steel was first floated in 1921 with the works becoming operational in 1924 and only ceasing operation in 1935. The ironworks used the limonite ore from nearby to make iron. To smelt the iron, coal and limestone were also necessary [ 1 ] and both limestone and the limonite were mined from the hills behind the works and ferried ...
The best yield of iron achievable from dry puddling is one ton of iron from 1.3 tons of pig iron (a yield of 77%), but the yield from wet puddling was nearly 100%. The production of mild steel in the puddling furnace was achieved circa 1850 [ citation needed ] in Westphalia , Germany and was patented in Great Britain on behalf of Lohage, Bremme ...

A bloomery is a type of metallurgical furnace once used widely for smelting iron from its oxides. The bloomery was the earliest form of smelter capable of smelting iron. Bloomeries produce a porous mass of iron and slag called a bloom. The mix of slag and iron in the bloom, termed sponge iron, is usually consolidated and further forged into ...
