FUNDAMENTALS OF IRON ORE SINTERING R. P. Bhagat INTRODUCTION The process of sinter making originated from a need to make use of fines generated in mines and in ore benefiCiation plants. With the development of sintering technology, a sintering plant has become a tremendous success for providing a phenomenal increase in
Iron ore sintering plant is an industry of high energy consumption and high pollution, while the major air pollution in iron and steel industry. ... Therefore, CO in circulating flue gas is combusted completely and much heat is released in sinter zone because the temperature of sinter .
Outotec Traveling Grate Sintering is based on our extensive experience and continuous R&D in fine-ore preparation and agglomeration. The process is suitable for sintering a wide range of raw materials, including iron, manganese, and nickel ores. Our innovative technologies, including industry-leading process automation
furnace process. In the sintering process fuel is in the form of coke breeze (or in the form various types of biomass) used for production of iron-ore sinter. Temperature measurement and monitoring is very important in the iron sintering process. Temperature can be a very good indicator of the behavior of the sintering process.
Dec 01, 2017· 1. Introduction. Iron and steel industry is the highest (15% ) energy consumption sectors in China.Traditionally, coke breeze supplies heat for the iron ore sintering. Coking and sintering contribute the second highest (26% ) energy consumption in the iron and steel production.Iron ore sintering is a pre-treatment process to prepare porous sinters with suitable strength which are the .
Regions in which iron ore has formed over millions of years (e.g. through volcanism) and can be mined economically are also referred to as iron ore deposits. Especially many ore deposits can be found in countries such as China, Australia, Brazil, India and Russia. These countries account for around 85 % of the total global iron ore mining volume.
Sintering of iron ore is a generic term which is used to describe the process whereby a sinter mix (raw mix or green mix) of iron ore fines, fluxes, fuel (coke breeze) and plant return fines (e.g. mill scale, blast furnace dust, and returned sinter fines etc.) are converted into a particular form of agglomerate.
Extraction and refining of metals involve the transfer of mass and heat within each phase and between the phases, one or more of which are in motion. For example, in blast furnace iron making, Fig. 5.1, iron oxide in the form of lumpy ore, sinter or pellet along with coke and limestone, are charged on the top of the furnace continuously. The ...
Apr 02, 2010· Like other sintering processes, iron ore sintering converts iron ore fines of often − 8 mm sizing into larger agglomerates, namely, sinter, between 5 and 50 mm particle size, which possess the physical and metallurgical characteristics and gas permeability required for efficient blast furnace operation. As shown in Figure 14.1, iron ore sintering is carried out in three stages: raw material ...
Large amounts of iron ore sinter are produced throughout the world. The development of sustainable and energy-efficient technologies has become increa.
In iron ore sintering, ignition is to supply upper feed with sufficient heat to ensure the coke combustion and materials sintering. And with air draft, the sintering proceeds from upper feed to lower completely.1) The energy consumption of conventional iron ore ignition using coal gas (CGI) in the

of sinter are: Particle Size Iron ore fines: The larger sized iron ore fines (> 10mm) does not take part in agglomeration rather is sometimes came un-sintered. The larger sized iron ore will segregate at a particular portion where sintering will be fast leaving behind the other portion. This situation will generate heterogeneous sinter chemistry.
Q. sintering of iron ore 1. INTRODUCTION :- 40 to 50% iron ore becomes under size which may create pollution in the plant of the mine site. For the utilization of the variable ore, it is necessary to agglomerate the fines into the required size for charging in the blast furnace. Agglomeration is the size incensement process of the fines ore.
Optimization of gaseous fuel injection for saving energy consumption and improving imbalance of heat distribution in iron ore sintering. Highlights•The heat pattern can be controlled by adjusting the gaseous fuel concentration.•Gaseous fuel segregation was firstly proposed for energy efficiency optimization.•The new method has great potential for green and efficient production of sinters ...
Jul 01, 2020· Sandi Johnson Last Modified Date: July 01, 2020 . Iron ore sintering is a type of powder metallurgy used to pre-treat iron before using it in manufacturing applications. Sintering involves heating iron powder to partially, but not completely, melt the iron particles. The exact process used and additional elements involved vary, with some methods using gas or electricity in addition to heat.
Coke is the best fuel for iron ore sintering. Size ... heat consumption and water . content in the mix are also very relevant factors. The 3D X-ray tomography technique has also been used .
It is possible that a use of a magnetite iron ore as a sinter raw material contributes for decreasing a bonding agent rate due to reoxidation heat of magnetite to hematite. 8) But it is still in consideration if a use of a magnetite iron ore has a full effect in decreasing a bonding agent rate because magnetite possibly remains in an iron ore ...
Sintering is a complex industrial process that applies heat to fine particles of iron ore and other materials to produce sinter, a solidified porous material used in blast furnaces. The sintering process needs to be carefully adjusted, so that the combustion zone reaches the bottom of the material just before the discharge end. This is known as the burn-through point.
The sintering technology is basically an agglomeration process for the iron ore fines which is dependent on heat to melt the surface of the smaller particles together to form larger agglomerates. A typical sinter plant consists of a number of sequential operating units with the sinter machine at the heart of the plant.
