احصل على السعرMaking cast iron 1 Iron ore is dug out of the earth in surface mines. The ore is obtained in lumps ranging in size from more than 40 in (1 m) in diameter to less than in (1 mm) in diameter. To produce cast iron or steel, the lumps must be 1 in (7
احصل على السعرThe ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being

احصل على السعرThis iron ore is then converted into various types of iron but first it is processed in a blast furnace to produce pig iron. Used by itself, pig iron has few uses due to its brittle nature. Alloyed with other metals, pig iron takes on new uses.
احصل على السعرHand tool Hand tool Iron and steel tools: Iron technology was derived from the known art of reducing copper and bronze. The principal requirement was a furnace capable of maintaining a reducing atmosphere—, one in which a high temperature could be maintained from a good draft of air. The furnace had to be tall enough to allow the iron to drop from the smelting zone and form a slaggy

احصل على السعرSlag is lighter than molten iron ore, so it rises to the surface and can easily be removed. The hot iron is then poured into molds to produce pig iron or directly prepared for steel production. Pig iron still contains between % and % carbon, along with other impurities, and it's brittle and difficult to work
احصل على السعرManufactured natural gas of this type (as opposed to naturally occurring gas) was first brought to the United States in 1816, when it was used to light the streets of Baltimore, Maryland. However, this manufactured gas was much less efficient, and less environmentally friendly, than modern natural gas that comes from underground.
