The carbon in the coke reacts with the oxygen to produce a reducing gas, carbon monoxide (CO) according to the following reaction: 2 C (s) + O 2 (g) → 2 CO + Heat. In the upper region of the blast furnace where temperature range from 600 to 700 C. the iron ore or iron oxide is reacts with the gaseous CO reductant to produce iron: Fe 2 O 3 (s ...

a function of the blast furnace requirements,5–14 which impose restrictions on sinter features such as basicity, reducibility, strength, etc. In daily plant operations, it is necessary to address the actual availability of raw materials and requirements for the blast furnace to reach an optimal performance point. Iron ore features do not

Sinter is the primary feed material for making iron and steel in a blast furnace. According to the U.S. Environmental Protection Agency, the sintering process converts fine-sized raw materials, including iron ore, coke …

Sinter is the primary feed material for making iron in a blast furnace. Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200°C in a continuous belt-fed furnace. Sinter feed composition control is important because the various sinter feed ...

Sinter plants agglomerate iron ore fines with other fine materials at high temperature, to create a product that can be used in a blast furnace. The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts …

In iron ore sinter plants blast furnace dust and other fine-grained residues which are rich in iron or carbon content are recycled. The carbon contained in the blast furnace dust can be used to replace coke breeze which is added to the charge as fuel for the sintering process. However, there is no information in the literature on the carbon ...

2 Blast furnace (BF) dust is a typical refractory iron resource. A novel technology-based utilization of BF dust as iron carbide and carbon concentrate by applying carburization roasting followed by magnetic separation and acid leaching is proposed. Under optimized conditions, an electric arc furnace (EAF) burden assaying 80.79% Fe and 7.63% C with a corresponding …

BF burden, blast furnace, Hot metal, Iron ore, iron ore pellets, sinter, Use of Iron Ore Pellets in Blast Furnace Burden Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8-20 mm in diameter by a ...

For efficient operation of a blast furnace, a completely fluxed (CaO/SiO 2 = 1.2–1.5 for different melting conditions) agglomerated (10–60 mm) iron ore material with the highest economically feasible iron content is required, uniform in chemical composition and size, preferably with the maximum permissible residual carbon content for the production of the …

The use of low-SiO 2 sinter in the Kobe No. 3 Blast Furnace has brought about the increase in overall permeability due to an increase in permeability at the lower part of the furnace, in spite of a decrease in the upper part. This increase has contributed to an appreciable increase in the ore/coke ratio and rate of pulverized coal injection.
