Pig Iron Production (Post Blast Furnace Era)
Abstract. It has become an environmental drive world-wide to reduce the production of Carbon Dioxide (CO 2) in the steelmaking process.Alternative reductants other than coal-based materials has been found to be a true replacement with resultant major reduction in CO 2, by using "cleaner" reductants like natural gas.Coke …
From pig iron to crude steel
The temperature of the pig iron melt rises from 1250 °C to over 1600 °C. For this reason, approx. 20 % iron scrap is added for cooling in order to protect the converter lined with stones from excessive temperatures. Iron ore or sponge iron (from the direct reduced iron process) can also be used for cooling. After 20 minutes of oxygen supply ...

Induction Furnace and Steelmaking – IspatGuru
Induction furnace is a type of furnace for steelmaking which uses electrical energy for its operation. Induction furnace (IF) steelmaking is one of the two electrical steelmaking processes. The other process for electrical steelmaking uses an electric arc furnace (EAF). Though IFs are being used since a long time, the production of mild …
Basic Oxygen Furnace Steelmaking
The Basic Oxygen Steelmaking process differs from the EAF is that BOF is self-sufficient in energy. The primary raw materials for the BOP are 70-80% liquid hot metal from the blast furnace and the steel scrap need to be balanced. These are charged into the Basic Oxygen Furnace (BOF) vessel. Oxygen (>99.5% pure) is "blown" into the BOF at ...

Pig Iron Production – Interstahl
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 graphite on the raw material.
Overview of Foundry Processes and Technologies:
machined iron castings. Metal foundries produce molten iron by melting scrap iron, pig iron, and scrap steel in a traditional coke-fired cupola furnace, or in electric-induction or electric-arc furnaces. Molten iron is refined by adding alloying metals into either the furnace or a ladle. It is then moved to a pouring station for pouring into molds.
