Effect of Oxides of Magnesium and Manganese and the

28.03.2016· It was established by laboratory studies and confirmed by factory tests that the filterability of molten blast-furnace slag is affected by the presence of the oxides MgO, MnO, and CaO, which are added to charge that is used to make sinter. The magnitude of this effect depends on the composition of the minerals that contain these oxides.

effect of high manganese sinter in blast furnace

The Effect on Blast Furnace Process of Changed Pellet Size . sinter plant was closed down. The average pellet burden is two thirds MPBO (Olivine pellets from LKAB Manganese slag 8 6 kg/thm Coldbonded briquettes 3 51 kg/thm The only effect that can be seen on the blast furnace process is a decrease in gas utilisation of two units.

Effect of Sinter Mix Composition and Additives on the

01.11.1955· Effect of variations in sinter feed composition on sinter strength, bulk density, re-ducibility, stone composition, and microstructure were determined by sintering experimental samples on a production sintering machine. Increasing amounts of roll scale, ore fines, return fines, and blast furnace slag were most beneficial to feed permeability, sinter bulk density, and strength. Burnt lime

Xiong, X.; Liu, D.; " Studies on production of high carbon ferromanganese in blast furnace with high proportion of sinter and improvement in manganese recovery ". The Proceedings of INFACON 8, pp

Influence of high grade iron ore usage on the performance

of using high grade ore to the performance of Sintering and Blast Furnace processes in terms of energy savings, CO 2 emissions, and logistic benefits to the mills in the region. Keywords: high grade iron ore, sinter, blast furnace, Brazilian fines, pot sinter, Alumina * Msc. Metallurgical Engineer R&D Technical marketing Vale S.A. Brasil

Influence of sinter basicity (CaO/SiO2) on low and high

24.08.2016· Iron ore sinter, constituting a major proportion of blast furnace burden, significantly impacts the blast furnace performance. The stone composition of iron ore fines, particularly alumina, sinter basicity and sinter MgO together with the thermal conditions that sinter blends are subjected to play an important role in the formation of mineral phases in sinter.

Hearth dia of possco b/f increases from 9.5-13.5 Hearth area increased from 1660 mtr sq -3800 mtr sq . Now there are nearly 700 blast furnace available in world.

Sinter plant Wikipedia

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

Reduction Degradation Behavior of Sinter in the Blast

Laboratory tests on the reduction degradation behavior of sinter were carried out to clarify the influence of each factor, which includes reduction degradation index (RDI), reducibility index (RI), and temperature profile.Furthermore, the materials were extracted from the shaft of the working blast furnace to ascertain the validity of the tests results.

Iron Ore Sinter IspatGuru

Iron ore sinter or simply called sinter is usually the major component of a blast furnace iron bearing burden material. Sinter normally consists of various mineral phases produced by sintering of iron ore fines with fluxes, metallurgical wastes and a solid fuel. Coke breeze is normally used as fuel in the sinter mix since it supplies necessary heat energy for sintering of sinter mix. Fig 1

Sintering Wikipedia

Sintering or frittage is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction.. Sintering happens naturally in mineral deposits or as a manufacturing process used with metals, ceramics, plastics, and other materials.The atoms in the materials diffuse across the boundaries of the particles, fusing the particles

Blast furnace Mn recovery Slag high basicity (upper limit: avoid 2CaO.SiO2 formation) high MgO% Al2O3 <15% to avoid MgO.Al2O3 formation High temperature where liquid metal and slag drip through coke (here most of the reduction occurs) sinter must have the required chemistry and a short range of softening temperature air blast must be injected at high temperature oxygen may be introduced

Blast Furnace Process an overview ScienceDirect Topics

01.01.2010· In blast furnace process, the blast air has high N 2 content (typically 70–75%) and in the off-gas around 50%. Some nitrogen is dissolved in iron, and typical values are about 50 ppm in hot metal. In converter process, the CO-gas evolution efficiently flushes the liquid steel and [N]-contents down to 20–10 ppm are attained. If blowing is continued to reach extremely low [C] level (far
