Suitability of Auger Pressing Briquettes for Blast Furnace Use Based on Laboratory Tests

Publication Type:Academic Journal

Source(s):Minerals, Vol 12, Iss 868, p 868 (2022)

Abstract:Briquetting is a process in which fine materials unsuitable for use as such are agglomerated to achieve a larger particle size. Auger pressing is a novel briquetting method to efficiently improve the recycling of by-products from iron and steelmaking. ...

Reduction of Acid Iron Ore Pellets under Simulated Wall and Center Conditions in a Blast Furnace Shaft

Publication Type:Academic Journal

Source(s):Minerals, Vol 12, Iss 741, p 741 (2022)

Abstract:The operational conditions, including temperature and gas composition, vary along the radial position in a blast furnace. Nevertheless, very few studies can be found in the literature that discuss how the reduction behavior of the ferrous burden varies...

Experiments and simulations on a cold-flow blast furnace hearth model

Publication Type:Academic Journal

Source(s):Chemical Engineering Science: X, Vol 13, Iss , Pp 100120- (2022)

Abstract:The blast furnace hearth plays an important role in the operational stability and lifetime of the reactor. The quasi-stagnant bed of coke particles termed the deadman undergoes complex interaction with the flowing hot metal, and remains largely ill-und...

Revisiting the Rist diagram for predicting operating conditions in blast furnaces with multiple injections [version 1; peer review: 2 approved]

Publication Type:Academic Journal

Source(s):Open Research Europe, Vol 1 (2021)

Abstract:Background: The Rist diagram is useful for predicting changes in blast furnaces when the operating conditions are modified. In this paper, we revisit this methodology to provide a general model with additions and corrections. The reason for this is to ...

Effect of Iron Ore Pellet Size on Metallurgical Properties

Publication Type:Academic Journal

Source(s):Metals, Vol 12, Iss 302, p 302 (2022)

Abstract:Iron ore pellets are small and hard spherical particles agglomerated from a fine iron ore concentrate. They are used in the blast furnace process to produce hot metal. The diameter of blast furnace pellets is usually between 8 and 16 mm. In this study,...
