The Sintering Process of Iron Ore Fines IspatGuru
Mar 09, 2013The sintering process is used to agglomerate a mix of iron ores (blend), return fines, fluxes and coke, with a particle size of less than 10 mm, so that the resulting sinter, with a screened size of 10 mm to 30 mm, can withstand pressure and temperature conditions in the blast furnace. Principle of sintering

Sintering: A Step Between Mining Iron Ore and Steelmaking
Jun 11, 2019The production of high-quality sinter is crucial for assuring consistent, stable furnace productivity with a low consumption of reductants. Sinter 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.

Iron ore sintering ScienceDirect
Jan 01, 2022Iron ore sinter typically constitutes more than 70% of the blast furnace ferrous burden in modern blast furnaces in East Asia. Granulation and thermal densification are the two most important steps in iron ore sintering, and determine the quality of the resultant sinter and the performance of the sintering process.

Ore Sintering an overview ScienceDirect Topics
Apr 02, 2010Ore Sintering. The aim of the MEBIOS process is the formation of a ventilation route in the sintering bed by creating a low-density area around the large pellets arising from a kind of wall effect and suppression of sinter bed shrinkage due to support of the load by the dense large pellets in the upper part of the sinter bed. From: Iron Ore, 2015

Influence of Oxygen Supply in an Iron Ore Sintering Process
the quality aspects of sintered ores. In the sintering process, productivity is determined by vertical fuel combustion speed or elapsed time for the complete combustion of coke in the bed. The quality indices are composite of strength and FeO content of the sintered ore. In order to maximize the productivity and quality of the

The Sintering Process of Iron Ore Fines IspatGuru
Mar 09, 2013Sintering is a thermal process (carried out at 1300 deg C to 1400 deg C) by which a mixture of iron ore, return fines, recycled products of the steel plant industry (such as mill scale, blast furnace dusts, etc.), slag forming elements, fluxes and coke fines are agglomerated in a sinter plant with the purpose of manufacturing a sintered product
