Ore Sinter an overview ScienceDirect Topics
547 Summary In this chapter, we learned that three main ferrous burden materials are used in BF operation; lump ore, sinter, and pellets The types of iron ores used to produce these three ferrous charge materials and the related production methods were described The various analysis methods used to determine the quality of the BF chargeSinter quality begins with the mined iron ore and the proper selection and mixing of the raw materials Inhomogeneous raw mix can affect permeability and cause an increase in fuel consumption During the iron ore sintering process in iron and steel manufacturing, an online analyzer can be used to determine the elemental composition Sintering: A Step Between Mining Iron Ore and Steelmaking
Preparation of Iron Ore Micropellets and Their Effect on Sinter
At present around 6–7% of iron ore slimes, out of total production, are being generated and accumulated at iron ore mine sites of National Mineral Development Corporation Limited, India The accumulated slimes of finer size and relatively inferior grade should be utilized in an economical way for sustainable mining These slimes can be 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 furnaceThe 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 Sinter plant
A comparative study of pellets, sinter and mixed ferrous burden
Two halves of the ferrous burden (pellet and sinter mixture) quenched at 1505°C (PPellet, SSinter, RC Regular coke) Figure 10 Measured S value for di ff erent burden type ( S value; aHPS can be treated as an environmentally sustainable process as we can utilize iron ore fines and consume less coke, which is the need of the hour (ii) The hyperparametertuned ANN model showed a prediction accuracy of over 99% and an MSE of 278 × 10 –4 It offers the high accuracy of the proposed prediction modelPrediction of Sinter Properties Using a HyperParameterTuned
Iron ore Climate Action
The production of iron ore pellets can be described as follows: Nonagglomerated iron ores (sinter fines) are mixed together with additives in a ratio that depends on the desired pellet quality and on the quality of the sinter fines The mixture is then brought into a round pellets shape (“green pellets”) and burnt at a temperature betweenIron ore pellet feed premiums continued to edge lower in line with tepid pellet demand in the domestic Chinese market, while sinterfeed cargo prices edged up in line with an increase in demand for imports, sources told Fastmarkets Key drivers for the ironore market High inventories and weak demand continued to weigh on seaborne Highgrade iron ore prices track dip in futures; sinter feed
Effect of Basicity on the Reduction Behavior of Iron Ore Pellets
Physicochemical properties of the iron ore pellets depend on the iron oxide concentrate, gangue content and the amount of fluxes added The objective of this present work is to study the reducibility as well as the softening–melting behavior of the iron ore bearing fines (mainly containing hematite) pellet with lime to silica ratio (C/S) varying Iron ore fines were mixed with 05% bentonite and 187% coke equivalent to 15% carbon As it has been found in earlier studies that 05% bentonite and 15% carbon are the optimum quantity requirement in acidic hematite pellets, the above mix proportion was used for this studyAfter making the pellet mix, the mixture was pelletized Kinetics of Carbon Oxidation During Induration of Hematite Ore Pellet
