In April 2011 the industrial stiff extrusion line based on the Steele 25 Extruder for the production of the sludge BF dust and iron ore fines briquettes for the small-scale BF was commissioned in Rourkela West Bengali India. 5 The capacity of this line is 20 tons per hour or an average 6000 tons per month with two shifts per day working.
A self-reduced intermediate product from iron and steel plants waste materials using a briquetting process. iron-bearing materials in blast furnace.. of iron ore andor by smelting reduction.
and unsuitable for iron-smelting in conventional pig iron blast furnace was also extensively employed in the Low Shaft Furnace Pilot Plant investiga-tional trials. In the lumpy form of burden iron are fines 70 below 6mm was employed directly. The slag basicity CaOSiO2 of 1.0 to 1.2 was normally aimed.
Mathematical modeling of a blast furnace smelting by improving the iron ore raw materials and coke. Proceedings of the Tenth Israeli-Russian Bi-National Workshop-2011 The optimization of composition structure and properties of metals oxides composites nano and amorphous materials June 2023 2011 Arial Israel. Pp. 168175.
This concentrated ore is mixed with limestone CaCO 3 and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.
The smelting of iron in a blast furnace involves the following processes 1. Combustion The air blown into the bottom of the furnace is heated using the hot waste gases from the top. The coke essentially impure carbon burns in the blast of hot air to form carbon dioxide - a strongly exothermic reaction. 2.
the integrated steelmaking process featuring the blast furnacebasic oxygen furnace BFBOF where iron ore is the major source of iron units and electric steelmaking based on the electric arc furnace EAF where steel scrap or direct reduced iron DRI are the major iron feedstock materials. Figure 1 major steelmaking process routes.

Metallic iron is produced from a composition formed from a mixture of iron ore particles and particles of a reductant made of a biomass material a coal or coke in a particulate form together with a flux and is processed in a loose un-agglomerated non-pelletized non-briquetted form in a reducing furnace to produce metallic iron directly from the ore.
Jan 29 2021 The metallurgical properties of blast-furnace ore and ore-coal extrusion briquettes BREX based on hematite iron ore concentrate are studied. With respect to values of hot strength brex occupy an intermediate position between sinter and pellets. The reduction capacity for brex is significantly reduced with simultaneous addition of flux and solid fuel which may be associated with a reduction.
comparison of the operation parameters of the Blast Furnace working on the iron ore and on the charge with 80 of the brex and 20 of the iron ore Table 1. Table 1.
A new blast-furnace smelting technology has been developed the technology making it possible to improve environmental conditions and reduce by 0.2-2.1 the quantities of natural materials used.
Feb 18 2021 Table of ContentsPreparation of PelletsExperimental Smelting OperationExperimental ResultsIndustrial Application Fines and concentrates must be consolidated or agglomerated into larger masses before they can be smelted in a commercial blast furnace. Such agglomeration is usually done by sintering pelletizing nodulizing or briquetting.
Jul 20 2014 The first commercial trial involving the use of the briquettes in a blast furnace as the main component of the charge successfully evolved into standard practice on the furnace.For more than two-and-a-half years the small blast furnace at Suraj Products Ltd. in Rourkela Fig. 1 was operated on a charge composed of brex 80 and high-grade iron ore of the 1550 mm fraction 20.
Apr 25 2017 As a new type of ironmaking raw material CCB carbon composite iron ore hot briquette is produced from a mixture of fine ore and fine coal by a hot-briquetting process using the thermal plasticity of coal.12 Compared with a cold bond pellet coal in CCB is used as a reductant and a binder without the need for an additional inorganic binder.. Compared with a cold-bonded coal composite.
