Modeling Sintering Process of Iron Ore Jose Adilson de Castro Graduate Program on Metallurgical Engineering Federal Fluminense University Brazil 1. Introduction In this chapter, a methodology for simulating th e sintering process of iron ore is presented. In order to study the process parameters and inner phenomena, a mathematical model
Aug 06, 2013· It is an agglomeration process achieved through combustion. In this process air is sucked at the sinter strand through a bed of raw mixture (also called sinter mix) of iron ore fines, limestone, dolomite, sand and quartzite fines (flux), solid fuel (coke breeze or anthracite) and metallurgical wastes (collected dusts, sludge and mill scale etc).
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 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 .
May 07, 2011· The remaining ironrich powder is rolled into balls and fired in a furnace to produce strong, marblesized pellets that contain 60% to 65% iron. Sinter is produced from fine raw ore, small coke, sandsized limestone and numerous other steel plant waste materials that contain some iron.
Jun 15, 2010· Iron ore fluxed sinter is the main ferrous burden of Jindal south west steel limited (JSWSL) blast furnaces. In sinter plant fluxes including limestone and dolomite are added to improve the sinter properties of iron ore and to provide an appropriate slag composition of the blast furnace. The raw material grain size affects the sinter process ...
One sinter machine of 180 cum sintering area with specific productivity of /sqm/hr with rotating circular cooler of Chinese technology. 13 nos. of bunkers for storage of various raw materials like iron ore fines, breeze coke, dolomite, limestone, sand, met. Waste etc and a mixing drum of dia x 16 m length for mixing of raw materials.
Jun 05, 2016· Zhou et al. considered most of the important physicochemical reactions, in which coke, limestone, dolomite, and iron ore particles were treated with characteristic size distributions. Then, Zhao et al. [20] modified Zhou''s model [15] by integrating into an available granulation model to provide a novel description of coke positioning within ...
Blast furnace produces Hot metal (Liquid Iron) using Iron ore, Coke, Sinter, Pellets and fluxes such as Limestone, Pyroxenite, Quartzite, Dolomite, Mn Ore reacting with oxygen from pre heated air. This entire process of production of hot metal is associated with various
At the top of the furnace the iron ore in pellet form, together with the coal or coke and limestone (CaCO3) or quicklime (CaO), are introduced whilst at the bottom hot air is added with the aim of making the combustion of the coke easier, this interacts to create a reducing atmosphere for the iron.
1. Iron ore, coal, coke and limestone are the major raw materials required for production of steel. The inbound raw materials are received and unloaded at a Raw Material Unloading Yard (RMUY). The unloaded raw materials are processed at treatment plants (Coke, Sinter and Pellet Plants) from where they are sent to a blast furnace for iron making.
System For The Proportioning Of Iron Ore In A Sintering Proce. The proportioning of iron ore is the first step of the sintering processt mixes different kinds of iron ores with coke, limestone, dolomite, and returned sinter to produce a raw mix fo.

Evaluation of sintering behaviour based on ore,New pretreatment and sintering technologies are therefore required to tackle the gradual change in the quality of iron ore fin In the sintering process, iron ore fines are first granulated with fluxes such as limestone and coke breeze, and are then loaded and fired in a sinter machineControl of the grain size distribution of T the raw .
Creating Iron | HowStuffWorks The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.
Generally before sintering a chargemix is prepared that consists of iron ore fines, fluxes (limestone and/or dolomite), fuel (coke breeze), sinter returnfines, and sometimes some wasterecycling plant materials. Therefore, efficiency of producing good quality sinter depends on many characteristics of the charge mix.
Sinter is the primary feed material for making iron in a blast furnace, and we have previously written about sintering and how it is a step between mining ore and steelmaking.. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering .
Sinter Production The sintering process converts finesized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace.
A. Iron ore sintering is considered a 1D transient process; the lateral transfer of heat and mass across the bed being negligible B. The continuum of the gas (O2, CO2, CO, H2O and N2) and solid (coke, limestone, lime, dolomite, magnesia, water, hematite and magnetite) phases; with the gases flowing through a stationary bed of solids
The iron ore blend, limestone, dolomite, quicklime and fuel are matched to produce sinter with %, %,, %. The chemical compositions and ratios of raw materials are shown in Table 1. The test used four kinds of solid fuel, one of which is coke breeze, the others are three types of biomass fuels,
sinter containing lime stone is higher than that dolomite . Min et al [4] illustrated that the six additives, limestone, lime, magnesite, magnesia, dolomite and lightburneddolomite to iron ore for investigating their influences on the pellet quality. For green balls, adding lime and lightburneddolomite makes
The raw materials used to produce Pig iron in a blast furnace are iron ore, Coke, Sinter and lime stone. Iron ores are mainly iron oxides and include magnetite,... Get Price; Mathematical model of thermal processes in an iron ore sintering bed. A raw mix of iron ores, limestone, and fuel coke fines forms a bed on a traveling grate.
