Blast Furnace Ironmaking Process Using Pre-reduced Iron Ore197 Кб. Fine ore is a raw material for sinter that is the main component of the blast furnace burden.A fluidized bed is used when reducing fine iron ore directly5-7), whereas a shaft furnace is used when reducing lump ore or pellets.

processed ore include sinter and briquettes. The average iron content of pellets is 63 percent. ... coarser than about No. 10 mesh to be acceptable as blast furnace feed without further treatment. Finer concentrates are agglomerated into small "green" pellets, which are classified as either acid pellets or flux ... The pellets are hardened by a ...

Iron ore pellets are produced from the iron ore concentrate by pelletizing and sintering and are used as the feedstock for the blast furnace process. Metinvest offers a range of iron ore pellets for the blast furnace process, such as non-fluxed pellets produced by Central GOK with a basicity of 0.1. and 65.5% iron content, non-fluxed pellets ...

Hatch has compared the merits of using sinter and pellets in the blast furnace to help steel producers evaluate the impact of increased pellet usage in the blast furnace burden. 2.2 Comparing Sinter and Pellets Sinter and pellets are agglomerated forms of iron ore, both suitable for use as blast furnace burden materials.

Fluxed pellets exhibit good strength, improved reducibility, swelling and softening melting characteristics. Because of these properties fluxed pellets give better performance in the blast furnace. Metallics in BF burden. Sinter, pellet and the calibrated lump ores are the three iron bearing metallics normally used in the blast furnace burden.

Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Compared with pellets, production of sinter is cheaper, and compared with lump ore, fluxed sinter is often more reducible with better softening characteristics.

lump (>6.3mm) or sinter fines (<6.3mm). The difference for the consumer is that lump can be fed directly into the blast furnace while fines must first go through a process known as sintering where they are agglomerated into crude pellets called 'sinter'. This step is necessary to maintain permeability of the blast

Reduction of Iron Ore Pellets, Sinter, and Lump Ore under Simulated Blast Furnace Conditions Anne Heikkilä,* Mikko Iljana, Hauke Bartusch, and Timo Fabritius 1. Introduction A blast furnace (BF) is the most common process for hot metal production in …

Microfines of iron ore are generally utilized in Blast furnace in form of indurated pellets because sinter bed has limitation of accepting fines. Charging of acid pellets with basic sinter is the normal practice in blast furnace. However induration of pellets is very cost intensive. Further more, due to low angle of

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical ...

iron ore sintering vs pelletization. pelletising and sintering of iron ore. sintering vs pelletizing iron ore Abstract Pelletization is one of useful processes for the agglomeration of iron ore or concentrat However, manganese ore fines are mainly agglomerated by sintering due to its high combined water which adversely affects the roasting performance of pellets.

–Pellets are a direct charge input and require less processing –Steel mills balance the benefit of pellets vs. cost. –Pellets allow steel mills to: •Improve productivity per cubic meter of blast furnace capacity (65% pellets vs 62% sinter) •Limit harmful emissions as pellets emit less CO2, fine dust and air pollution compared to sinter

Abstract The present research paper discussed the utilization of plant waste materials such as blast furnace flue dust and sludge as macro pellets and use of these macro pellets in the production of sinter. Wastes addition as pellets to the sinter modifies the productivity of the laboratory grade sinter machine as well as the better mechanical strength of sinter. At the same it also decreases ...

The performance of a blast furnace depends to a great extent on the physical and chemical characteristics of the materials. The burden materials, which are charged through the throat, are coke, lump ores, and agglomerated ores in the form of sinter or pellets. Lump ores are significantly cheaper than pellets and sinters.

Answer (1 of 2): What is Pelletization?

Answer: The Old Metallurgical Engineer and Steelmaker says: A sinter plant processes fine-grained raw materials such as iron ore fines, coke fines (a.k.a. "coke breeze"), flue dust and scale pit scrapings, into much larger particles of sinter, suitable charging into the blast furnace. Sintering ...

As per thumb rule, the use of fluxed sinter indicate that for each 100 kg of limestone per net ton of hot metal removed from the blast furnace burden and charged into the sinter plant to make a fluxed sinter, approximately 20-35 kg of metallurgical coke per ton of hot metal is saved and around 3 % to 5 % improvement in the productivity of blast ...

Sinter is the primary feed material for making iron and steel in a blast furnace.
