Pig Iron - Wikipedia

The iron making blast furnace itself is built in the form of a tall structure, ... The "pig iron" produced by the blast furnace has a relatively high carbon content of around 4–5%, ... the chemical process inside the blast furnace remains the same. Extraction of iron from its ore is the third and the penultimate process in the Metallurgy. The extraction of metals and its isolation occurs over a few major steps: ... To further reduce the carbon content of pig iron, it is melted again with scraps of iron and coke and subjected to the blast of hot air. ... Leaching offers excellent chemical ...

Metallurgic Processes | Boundless Chemistry

The pig iron was melted in a running-out furnace and then run out into a trough. This process oxidized the silicon to form a slag, which floated on the iron and was removed by lowering a dam at the end of the trough. The product of this process was a white metal known as finers metal or refined iron. Asmet source a range of Pig Iron grades direct from leading world producers and maintain strategic stocks to offer a reliable, high quality supply at competitive prices. Our foundry metallurgists have extensive experience in helping our customers select the optimum grade of pig iron and charge make-up to suit their casting process. Some pig iron is used to make cast iron. the chemical process inside the blast furnace remains the same. where iron ore. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron. steel stack lined with refractory brick. The blast furnace is a huge.

How Iron Is Made - Material, Manufacture, Making, History ...

Basic oxygen steelmaking is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into steel. The process is known as basic due to the chemical nature of the refractories—calcium oxide and magnesium oxide—that line the vessel to withstand the high …
