How does a blast furnace?
The blast furnace is formed by a series of chambers that form a cylindrical cavity, about 30 meters. Usually built with refractory brick and is lined with steel plates. Allows you to refine different materials and in particular, to produce pig iron, steel base, from iron ore. The pig iron is obtained by passing an air stream of a mixture of solid fuel and ore, in order to burn the impurities that presents him or to transform insoluble slag, which floats in the molten metal that can be separated by very simple procedures. The molten product accumulates in the crucible, or melting chamber, a cylindrical shape and located at the base. Above, the blast furnace is divided into two conical chambers known as harness and Cuba. Near the oven is to heat the air jets to over 500 º C. It enters into the chambers through those nozzles.
Who invented the blast furnace?
It is not known with accuracy the time of appearance of the first methods to melt the iron ore and produce utilitarian objects. But the first modern blast furnace was built in 1855 by English engineer Henry Bessemer.
Do you interrupt the work of the blast furnace?
No. The blast furnace is constantly loaded with iron ore being processed. In parallel, come out of the oven, without inte
