In an effort to develop breakthrough technologies that enable drastic reduction in CO2 emissions from steel industry (ULCOS project), the reduction of iron ore by pure hydrogen in a direct reduction shaft furnace was investigated. After experimental and modelling studies, a 2D, axisymmetrical steady-state model called REDUCTOR was developed to simulate a counter-current moving bed reactor in wh...

Sintering is a process by which a mixture of iron ores, fl uxes and coke is agglomerated in a sinter plant to manufacture a sinter product of a suitable composition, quality and granulometry to be used as burden material in the blast furnace. This process is studied and researched in the steelmaking industry in general, and in sinter plants in particular, as well as in universities and metallur...

Steelmaking is energy intensive, with manufacturing facilities representing some of the biggest point-source carbon dioxide (CO 2 ) emitters in UK. Efficiency improvements are essential rising costs, driving significant investment from UK iron and steel sector. However, industry still finds it difficult to justify waste heat recovery (WHR) projects, as individual schemes incorporating capture a...

Article presents the results of experimental studies fine-grained slag concrete based on mechanically activated steel West Siberian Metallurgical Plant (Novokuznetsk). The purpose research was to develop scientific principles for obtaining clinker-free steelmaking waste resources. For crushing binding properties initiation commercial equipment have been selected; coal industry Abashevskaya mine...
