Iron ore pelletization ScienceDirect

2015-1-1  15.1. Introduction. Iron ore lump, sinter, and pellets comprise the main burden of modern blast furnaces. However, sinter and pellets are now the dominant blast furnace burden, because the natural lump supply has declined dramatically due to depletion of the world's high-grade competent iron ore

Shaft Furnace an overview ScienceDirect Topics

The iron blast furnace (Fig. 47) is the most highly developed shaft furnace and can operate very efficiently not only as a heating unit but as a high temperature reaction chamber.Modern furnaces are nearly 30 m high (plus a considerable superstructure) and may be over 15 m in diameter at the hearth.

Detailed Modeling of the Direct Reduction of Iron Ore in a

The shaft furnace is divided into three sections (reduction, transition, and cooling), and the model is two-dimensional (cylindrical geometry for the upper se This paper addresses the modeling of the iron ore direct reduction process, a process likely to reduce CO₂ emissions from the steel industry.

Reduction Behavior of Carbon Composite Iron Ore Hot

The reduction and melting behavior of carbon composite iron ore hot briquette in shaft furnace are dis-cussed. As these agglomerates are made by the use of thermal plasticity of coal, the reduction rate by chain reactions in interface between ore and coal could be increased. The carbon composite iron ore

pelletisation iron ore ale-pycha.pl

[PDF] Iron ore pellet disintegration mechanism in

Abstract The disintegration behavior and mechanism of iron ore pellet in simulated shaft furnace conditions were investigated in details. Effects of temperature, reducing gas and gangue compositions were emphatically discussed. It was found that pellet disintegrated acutely as reduced by H2/CO = 0.8 at 550 °C. Gangue minerals in pellet were proved to ease the disintegration in various degrees.

Influence of Oxide and Silicate Melt Phases on the RDI of

Blast furnace or shaft furnace feed should form a perme-able bed of material, permitting gas flow through it uni-formly at a high rate. Iron ore concentrates in the form of fines are not suitable because, fines tend to pack into a non-permeable bed and also they are likely to be carried away as dust by the high gas flow rates.
