Blast Furnace Process an overview ScienceDirect Topics
2010-1-1 Important properties of sinter for blast furnace process are reducibility, size and size distribution, cold and hot strength, and softening and melting behavior. Typical sinter suitable for blast furnace process is from 15 to 25 mm, as is illustrated in Figure 1.1.10 [22].Another important property is the disintegration of sinter in reduction, which occurs during the transformation of

Waste as supplemental fuel in the blast furnace
2002-10-14 Fig. 1 shows a schematic of a simulated blast furnace, named as hot model, used in this study.To match the combustion conditions to a real situation, three LPG type gas heaters were used to blow hot air through the blow-pipe, and by this set up the temperature could be efficiently controlled in the range of 900–1100. °C.. Oxygen could be also injected

blast furnace Definition, Temperature, Diagrams,Facts
blast furnace, a vertical shaft furnace that produces liquid metals by the reaction of a flow of air introduced under pressure into the bottom of the furnace with a mixture of metallic ore, coke, and flux fed into the top. Blast furnaces are used to produce pig iron from iron ore for subsequent processing into steel, and they are also employed in processing lead, copper, and other metals.

A Review on Recycling and Reutilization of Blast Furnace
2021-6-3 A large amount of dust is formed as one of the primary by-products during the blast furnace ironmaking process. Besides iron and carbon, it contains a variety of valuable metals such as zinc, lead, and indium widely applied in many industry fields. However, it is difficult to recycle and reutilize blast furnace dust (BFD) due to complex composition, fine particle size,
