Throughout the 20th century, many new ironmaking processes were proposed, but it was not until the 1950s that potential substitutes for the blast furnace emerged. Direct reduction, in which iron ores are reduced at temperatures below the metal's melting point, had its origin in such experiments as the WibergSoderfors process introduced in Sweden in 1952 and the HyL process introduced in Mexico in .
Profitability Solutions: Using sinter in place of lump ore and pellets helps to reduce blast furnace fuel rate and CO 2 emissions.. Adding fluxed sinter feed to the blast furnace increases softening and melting temperature and improves reduction.
Raw material handling system An integrated steel plant has to stockpile and handle large tonnage of solid material to supply burden toHowever present trend in the Indian Steel industries is to go for higher usage of sinter in the blast furnace thereby raw Lime stone in the furnaces are reduced.

Effect of Sinter Mix Composition and Additives on the Quality Of Blast Furnace Sinter by E. C. Rudolphy, C. W. Boquist, and D. J. Carney Effect of variations in sinter feed composition on sinter strength, bulk density, re
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.
Sinter plant – Wikipedia, the free encyclopedia. Learn more » Sinter plants, in combination with . is still produced using the sinter plant,blast . waste generated in steel plants to enhance blast furnace .
Sintering machines No's 10 and 11 each have a sintering area of 252 m 2. Sinter is produced by sintering a blend of concentrates. Metallurgical coke fines are used to fuel sintering process. Limestone is used as a fluxing agent. The basicity of fluxed sinter is determined by blast furnace process.
The sinter produced alongwith other raw material is directly charged into the blast furnace for iron making.
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 .
Jun 29, 2010· Re: coke rate reduction in mini blast furnace 09/11/2008 6:10 AM telephoned me on this Roy is a well experienced person in Blast Furnace and sinter is a Guru for all of case you wish to have operational consultancy,or reaserch etc, Dr Roy is the correct man and he is available in Kolkutta also for you.
Mar 03, 2014· A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally iron, but also others such as lead or copper.. In a blast furnace, fuel, ores, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with oxygen enrichment) is blown into the lower section of the furnace through a series .
There are different ways in which the raw materials are charged into the blast furnace. Some blast furnaces use a "double bell" system where two "bells" are used to control the entry of raw material into the blast furnace. The purpose of the two bells is to minimize the loss of hot gases in the blast furnace.
• Reducing number of Blast furnaces in Europe • Increasing productivity • Increasing CO 2 concentration in the atmosphere • Close to theoretical minimum regarding reducing agents • BF is main producer of CO 2 within integrated steel works • Small possibilities to reduce CO 2 .
The sinter received at the stockhouse bins of the blast furnace was also sampled over a period of 24 hrs. Specla1 'samples were obtained dur~ng the Per~ods VIll and IX at the
