Effect of Sintering Performance of the Utilization of Blast Furnace Solid Wastes as Pellets ... large tonnage of different grades of fer ro-manganese (Medium and High carbon ferro-manganese) and ...
Mar 28, 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.
The high permeability of the sinter allows an increased blast volume and thus an increased productivity of the blast furnaces, leading to lower specific thermal losses. The high reducibility reduces the fixed carbon consumption. Both effects have been taken into account in a blast furnace model developed by ERAMET Research Center.

Therefore, in the present research, the authors reproduced the atmosphere in the blast furnace during high PCR operation and in operation with hydrogen gas (LNG, H 2) in order to investigate the effects of sinter quality and reducing gas composition on RDI and softening under load, in terms of pressure drop. Based on the results of these ...
Daily average slag and the corresponding hot metal samples were collected from blast furnace No.3 (1033m3 useful volume) of the Egyptian Iron and Steel Company (EISCO) charged with 100% self- fluxing sinter over a period of two months (from July to August 2015). The analyses of slag and metal were used to investigate the effects of temperature and basicity, defined as CaO/SiO2, on manganate ...
Jun 23, 2013 Blast furnace productivity greatly depends on the quality of sinter. Sinter is to have optimum grain distribution, high strength, high reducibility, high porosity, softening temperatures greater than 1250 deg C, constant FeO content in the range of 7 % to 8 % and constant basicity.
Feb 01, 1999 The aim of this work was to examine the use of mixtures of high basicity ore sinters and acidic pellets in blast furnace charge. The proportion of high basicity sinters and acidic pellets depends on both the nature and basicity of the latter and is used to obtain desired slag properties as well as sufficient reducibility and mechanical strength of the furnace charge.

2.2 Effect of High Ratio Coke Mixed Charging on Blast Furnace Operation 2.2.1 Effect on permeability of cohesive zone If high ratio coke mixed charge is performed in an actual blast furnace, there is concern that the thickness of the coke layer (coke slit) charged between the raw material layers may decrease, deteriorating gas perme-
The ratio should be not less than 7.5:1. Sinter quality Index (SQI): A relation between sinter usages in burden and productivity are well established. Now a day, almost all blast furnace usages a sinter in its burden charge. Quality of raw materials (iron ore, coke and sinter) is the prime factors which attribute the success of iron making ...
Santanu Chakraborty, in Treatise on Process Metallurgy: Industrial Processes, 2014. 5.3.7 Manganese Ore. Manganese ore is required in iron making to control the manganese content of the hot metal in the desired range. Unlike other plants, where manganese ore lump is used directly in blast furnace, in VSP, it was proposed to use manganese ore fines in sinter productions.
Abstract. Based on the furnace burden of high content of Al 2 O 3, the process of softening and melting and the characteristic of primary slag were studied with the increase of MgO content in the sinter and adding some MgO into the pellet.The results showed that the content of MgO in the primary slag increased with the increase of MgO in the sinter and pellet.
May 29, 2015 The effects of Al 2 O 3, MgO, and binary basicity on the viscosity of high alumina blast furnace slag are studied systematically at the temperatures of 1773 K and below using the orthogonal experimental design method.The results show that, at fixed binary basicity (CaO/SiO 2) between 1.1 and 1.2, higher Al 2 O 3 content increase the slag viscosity due to the polymerization of the aluminate ...

A large amount of finely dispersed manganese ore left after benefication operations or blown out from the furnaces is unsuitable for direct use in electric furnaces and blast furnaces, therefore it is necessary to granulate it in order to have the efficient use of its fine ore particles in metallurgy. To make our research more of practical use, we found it is reasonable not only work over ...

In the blast furnace process, iron bearing materials including iron ore, sinter, scrap, or other iron source along with a fuel, generally coke, and a flux, limestone, or dolomite are charged into the blast furnace from the top. The blast furnace burns part of the fuel to produce heat for melting the iron ore and the balance of the fuel is ...
The charge. When oxygen contacts blast-furnace iron, a great amount of heat is released by the ensuing exothermic reactions, especially the oxidation of silicon to silica, so that using only blast-furnace iron would result in a liquid steel temperature too high for casting.Therefore, before the hot metal is added, a specific amount of scrap is charged into the furnace.
