prior treatment of ore blast furnace thebushlodge

prior treatment of ore blast furnace. (BOF) route: The blast furnace uses iron ore, coke and limestone to produce molten ‘pig iron’ containing 4% to 5% carbon. A basic oxygen furnace converts pig iron into steel by reducing the carbon to less than one per cent by oxygen lancing. Read More.

Iron Ore Processing for the Blast Furnace

blast furnace process. The iron ore concentrate is now mixed and ready for the pelletizing process. Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about the size of a marble (between 1/4" and 1/2").

Blast Furnace an overview ScienceDirect Topics

Blast furnaces have grown considerably in size during the twentieth century. In the early days of the twentieth century, blast furnaces had a hearth diameter of 4–5 m and were producing around 100,000 THM per year, mostly from lump ore and coke. At the end of the twentieth century the biggest blast furnaces had between 14 and 15 m in hearth diameter, and were producing 3–4 million tons of

COREX® — SMELTING REDUCTION PROCESS

Operational results proved stable operations with a lump ore fraction up to 80%. In addition, no sinter and therefore no sinter plant is necessary for optimal operation. Use of Pure oxygen. While blast furnace operators aim to enrich the hot blast with oxygen, Corex already uses high-purity oxygen, resulting in nearly nitrogen-free top gas.

Production Dillinger

Pig iron, known to steelmakers as "hot metal", is produced in the blast furnaces from iron ore, coke, coal and additives. This is the task of ROGESA, a joint subsidiary of Dillinger and Saarstahl. ROGESA operates two blast furnaces of 11.2 and 12.0 m hearth diameter, respectively. Upstream of the blast furnaces are two sinter plants.
