Blast furnace is a continuous unit of shafttype. The charging of burden is conducted from above, through the typical charging unit, which is the gas damper of the blast is reduced rich iron ore (at present time resources of rich iron ore are preserved only in Australia and Brazil), sinter or pellets in the blast granular pellets are used instead of crude ore.

The blast furnace (BF) is a countercurrent gas–solid chemical reactor in which ironbearing materials, namely iron ore, sinter and pellet and fuel mainly coke, are charged from the top of the furnace, while hot blast enriched with oxygen and steam is blown from the bottom of the furnace through tuyeres.
Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from to inches. 4) and the iron content ranges from 50% to 70%. This iron rich ore can be charged directly into a blast furnace without any further processing.
The latest Primitive Technology video shows how to smelt iron ore in a draft furnace, without the need for a blower. It's one step closer to the iron age. ... Primitive Technology: Smelting Ore in a Draft Furnace This Cylindrical Furnace Requires No Manual Bellows, and Can Produce Iron from Raw Ore.
In traditional blast furnace iron making, the iron ore is fed to the blast furnace in one of three common forms: Lump, pellets or sinter. All of which are designed (in conjunction with coke) to maintain a porous feed bed in the blast furnace and thus facilitate rapid and uniform reduction of .
The assessed pellet premium is based on pellet with typical specifications of 65% iron, % alumina, 5% silica, % phosphorus and % sulfur, 250 cold crushing strength and a maximum sizing of % under 5 mm.

The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.
Apr 28, 2014· How A Blast Furnace Works The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.

Iron Ore Processing for the Blast Furnace (Courtesy of the National Steel Pellet Company) The following describes operations at the National Steel Pellet . ro re Global iron ore production data. blast furnaces to make pig iron, which is further processed to make steel. Highgrade iron ore mines can supply usable iron ore, known as directshipping ore, to blast furnaces, with minimal physical processing and no .
Blast Furnace. The furnace is charged with sinter pellets and rubble ore (iron bearing materials), flux and coke. Conventionally, the materials are charged through a rotating hopper distributor and twobell system, although many modern furnaces have the Paul Wurth bellless top which uses a rotating chute.
Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from to inches.
