Combustion behavior of granulated coke breeze in iron ore

Dec 01, 2018· 1. Introduction. Iron ore sintering is a very important process which produces sinter as a major burden for blast furnace ironmaking. In this process, iron ore and auxiliary materials, e.g., fluxes, unqualified sinter (called return fine), and coke breeze, are mixed, granulated and then sintered at

Other articles where Coke breeze is discussed: iron processing: Sintering: of fine coke (known as coke breeze) within the ore generates the necessary heat. Before being delivered to the sinter machine, the ore mixture is moistened to cause fine particles to stick to larger ones, and then the appropriate amount of coke is added. Initially, coke on the upper surface

Optimization of Coke Breeze Segregation in Sintering Bed

the blending ratios of the coke breeze, Ore N, and Ore R for each layer with the two blending patterns. The limestone, coke breeze and return fine used in the tests were gathered from the sintering plant. For 50mass% of pisolite ore ratio, the difference of combined water in upper layer and bottom layer was considered as 1.17mass% ( 0.7/30·50

Granulation of Coke Breeze Fine for Using in the Sintering

The iron ore sinter which was produced by using coke breeze without sieving yielded low productivity for both sinter machine and blast furnace. Furthermore, using coke breeze without sieving in sintering of an iron ore decreases the vertical velocity of sinter machine and increases the reduction time. Keywords: Coke fine, Granulation, Iron ore

What is a Coal Coke Breeze? Definition from Corrosionpedia

Mar 19, 2015· Coal coke breeze is a common backfill material used in cathodic protection. It is a type 1 carbonaceous backfill material. Coal coke breeze backfill has low resistivity and low ash content, and may be treated by the addition of 10% (by weight) commercial grade slaked lime. The fuel used in the iron ore sintering processes is coke breeze.

Effects of anthracite replacing coke breeze on iron ore

Anthracite coal as fuel for iron ore sintering is compared with coke breeze. Anthracite is lower in porosity, higher in density, and slower in combustion rate. With higher proportion of anthracite in fuel, permeability of sinter bed tends to decrease resulting in lower sinter productivity.

Sintering: A Step Between Mining Iron Ore and Steelmaking

According to the U.S. Environmental Protection Agency, the sintering process converts fine-sized 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.

Index Terms— coke breeze, charcoal, sintering process

The high consumption of coke breeze leads to its depletion as the most of the fossil fuels. Several researches, nowadays, focus on finding different alternatives that can replace the coke breeze either partially or completely. In this study, the charcoal was used as a supplementary fuel in the iron ore sintering process. Coke breeze

Optimisation of FeO in iron ore sinter at JSW Steel

Abstract. Coke breeze is the most common fuel used in sintering, and its usage depends on the alumina content and fineness of the sinter mix. The coke breeze consumption in the JSW Steel Limited sinter plant was high compared to many other sinter plants in the world, and as there was a local shortage, optimisation in the sinter plants was necessary.
