The iron and steel industry is still dependent on fossil coking coal. About 70% of the total steel production relies directly on fossil coal and coke inputs. Therefore, steel production contributes by ~7% of the global CO 2 emission. The reduction of CO 2 emission has been given highest priority by the iron- and steel-making sector due to the commitment of governments to mitigate CO 2 emission

This study was performed to evaluate the compressive strength and acid-resistant of polymer concrete using redispersible polymer powder(RPP) and blast furnace slag powder(BSP). Material used were ordinary portlant cement, recycled coarse aggregate, natural fine aggregate, redispersible polymer powder and blast furnace slag powder. The main experimental variables were the substitution ratio …
RDCIS 2 Emerging Scenario in Iron Making • More than 90% of world iron production is through Blast furnace technology route • Driving forces: Alternative Ironmaking technologies – Costly and scarce coking coal: Need to look beyond coking coal – possibility to use iron ore fines directly
Blast Furnace Reline project and it is possible that it will not go ahead. However if it does go ahead, it will be done in conjunction with the No.5 Blast Furnace reline project. Therefore, BlueScope Steel seeks DGR’s for the following alternatives: a) DGR’s for the
Blast Furnace The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron.

HIsarna is a substitute for the blast furnace process. To make liquid iron in a blast furnace iron ore and metallurgical coal (the raw materials) need to be preprocessed into sinter (lumps of iron ore) and pellets (small balls of iron ore) and cokes. The HIsarna
Blast Furnace Ironmaking: Analysis, Control, and Optimization uses a fundamental first principles approach to prepare a blast furnace mass and energy balance in Excel (TM). Robust descriptions of the main equipment and systems, process technologies, and best practices used in a modern blast furnace plant are detailed.
Plasma torches offer the opportunity to lower coke rate and carbon dioxide emissions by using a greater amount of electrical energy in blast furnace ironmaking.Coke replacement cases studied: ‒ The largest cost savings in hot metal production is to lower coke

Blast furnace ironmaking • Carbothermic reduction of iron ore (Hametite) in blast furnace is a well known process. Overall process is written as: • Ironore oxide mineral + gangue + Reducer (C) + flux + hot blast oxygen enriched air = Pig iron (liquid) + Slag
A mathematical model for the four-phase (gas, powder, liquid, and solids) flow in a two-dimensional ironmaking blast furnace is presented by extending the existing two-fluid flow models. The model describes the motion of gas, solid, and powder phases, based on the continuum approach, and implements the so-called force balance model for the flow of liquids, such as metal and slag in a blast
