Sorelmetal ® is treated to remove the sulfur, which allows for efficient and economical magnesium treatments.; Practically manganese free, Sorelmetal ® is used to dilute manganese in base iron in the ductile iron production process.; Because Sorelmetal ® is low in trace elements, it is the ideal choice of a high purity iron unit for the dilution of ...

Generation of iron and steel slag : NIPPON SLAG ASSOCIATION

Steelmaking slag is generated by the process that turns pig iron produced by a blast furnace into tough and highly workable steel. Converter slag is the oxidized material that is generated when lime and other auxiliary materials are added and oxygen is blown onto the pig iron in order to remove carbon, phosphorous, sulfur, and other components ...

Pig Iron Production – Interstahl

Diversity of pig iron properties. Pig iron usually consists of about 92 percent iron, three to four percent carbon, and varying amounts of silicon (0.5 to 3%), manganese (0.5 to 6%), phosphorous (0.1 to 2%) and traces of sulfur (0.01 to 0.05 percent). Grey pig-iron is produced when the pig-iron is cooled slowly and the carbon settles out as ...

In 1875, Britain accounted for 47% of world production of pig iron and almost 40% of steel. Forty percent of British output was exported to the U.S., which was rapidly building its rail and industrial infrastructure. The growth of pig iron output was dramatic. Britain went from 1.3 million tons in 1840 to 6.7 million in 1870 and 10.4 in 1913.

Further, solid pig iron is used as “pure” raw material and carbon source in EAFs. The blast furnace–BOF route produces almost 66% total crude steel, and EAF route accounts for about 31%, while the blast furnace–open hearth process, which dominated steelmaking in the first half of the 1900s, had only a share of about 3% left [ 7 ].

Pig-Iron Production - Google Sites

Pig-Iron Production from Microsoft Encarta. The basic materials used for the manufacture of pig iron are iron ore, coke, and limestone. The coke is burned as a fuel to heat the furnace; as it burns, the coke gives off carbon monoxide, which combines with the iron oxides in the ore, reducing them to metallic iron.

Bessemer process: 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 blown through the molten iron.

iron: Production and Refining Infoplease

Ductile iron is strong, shock resistant, and easily machined. Wrought iron is commercially purified iron. In the Aston process, pig iron is refined in a Bessemer converter and then poured into molten iron silicate slag. The resulting semisolid mass is passed between rollers that squeeze out most of the slag.
