    Integrated steel mill in the Netherlands.The two large towers are blast furnaces.. A steel mill or steelworks is an industrial plant for the manufacture of steel.It may be an integrated steel works carrying out all steps of steelmaking from smelting iron ore to rolled product, but may also be a plant where steel semi-finished casting products are made from molten pig iron or from scrap.

    en.wikipedia.org/wiki/Blast_furnace

    Cast iron is more brittle than wrought iron or steel, which required additional fining and then cementation or co-fusion to produce, but for menial activities such as farming it sufficed. By using the blast furnace, it was possible to produce larger quantities of tools such as ploughshares more efficiently than the bloomery.

    The formed carbon monoxide (CO) is flushed away in the fumes, while steel is formed. To increase the oxidizing power of the "heat", more iron oxide ore can be added. [4] The process is far slower than that of the Bessemer converter and thus easier to control and sample for quality assessment. Preparing a heat usually takes eight to eight and a ...

    Bessemer converter, schematic diagram. The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace. The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also ...

    Later designs incorporated horizontal steel or cast iron turbines, which were sometimes refitted into the old wheel mills. In most wheel-driven mills, a large gear-wheel called the pit wheel is mounted on the same axle as the water wheel and this drives a smaller gear-wheel, the wallower , on a main driveshaft running vertically from the bottom ...

    Laterite in Sơn Tây, Hanoi, Vietnam. Francis Buchanan-Hamilton first described and named a laterite formation in southern India in 1807. [4]: 65 He named it laterite from the Latin word later, which means a brick; this highly compacted and cemented soil can easily be cut into brick-shaped blocks for building.
