how much iron ore to make pig iron

Pig Iron Manufacturing Process - Metallurgist & Mineral Processing Engineer

In his second series the ore contained 0.15 per cent, phosphorus and the pig steel 0.01 to 0.10 per cent. Brown and Lathe, with an ore containing 1 per cent, phosphorus, obtained products with 0.031 to 0.49 per cent, phosphorus, but did not reduce the phosphorus in the pig steel to below 0.20 per cent, without excessive loss of iron in the slag.

How Do You Turn Iron Into Steel? - Steel Fabrication Services

In this method, the intermediate product, pig iron, is combined with steel scrap, usually under 30%, as well as a small amount of flux. Oxygen is blown into the furnace which increases the temperature to over 1700°C. The pressurised oxygen reacts with the high levels of carbon found in the pig iron and scrap, forming CO as well as CO2.

Hurstwic: Iron Production in the Viking Age

Inside the furnace, the temperature reached 1100-1300ºC (2000-2400ºF) at the bottom of the furnace near the iron. A reducing atmosphere was created, rich in carbon monoxide. The gas scavenged the oxygen from the iron compounds in the ore, converting them to elemental iron:

Coking Coal for steel production and alternatives

To make steel, metcoal is heated at around 1100 degrees C to remove water and other chemicals. This is done without the presence of oxygen. The result is a lump of near-pure carbon which is called coke. The coke is fed into a blast furnace along with 'raw' iron ore and some other minerals called fluxes. This produces pig iron.

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.
