Iron Ore Sinter IspatGuru

The reduction disintegration index RDI is defined as a quantitative measure of the disintegration of the sinter that could occur in the upper part of the blast furnace after some reduction Sinter with a high degree of reduction disintegration generates fines in the top of the furnace which affects the flow distribution within the blast furnace

Reduction of Iron Ore Pellets Sinter and Lump Ore under Simulated

It is found that lump ore has lowest reduction rate in all test conditions and at lower temperatures iron ore pellets reduce faster than sinter and this is reversed at higher temperatures Furthermore the reduction rate of sinter and iron ore pellets begins to resemble each other at higher temperatures FULL PAPER l

Extraction of Iron from its ores Iron dressing Reduction production

Reduction of iron ores The reduction process is the process of reducing iron oxides to iron by carbon monoxide resulting from coke in the blast furnace or by a mixture of carbon monoxide and hydrogen gases water gas resulting from natural gas in the Midrex furnace

What is the difference between pellet and sinter

Coke is used as a fuel and a reducing agent in melting iron ore It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself When coke is consumed it generates intense heat but little smoke making it ideal for smelting iron and steel What raw materials are added to the blast furnace

Iron Ore Pelletizing Process An Overview IntechOpen

The main used reduction reactors are the blast furnace BF and direct reduction reactors DR In the blast furnace iron is reduced and melted and the most common product is liquid iron called hot metal In direct reduction iron remains in solid state and the product is the so called direct reduced iron DRI

Low Carbon Production of Iron Steel Technology Options Economic
