Shaft Furnace Direct Reduction Technology - Midrex and Energiron
Advanced Materials Research, 2013Coke constitutes the major portion of ironmaking cost and its production causes the severe environmental concerns. So lower energy consumption, lower CO2 emission and waste recycling are driving the iron and steel industry to develop alternative, or coke-free, ironmaking process.

Modeling and Simulation of the MIDREX Shaft Furnace: Reduction, Transition and Cooling Zones
Jom, 2015Metallic iron used in steel industries is mostly obtained from a direct reduction process. The focus of this study is to simulate the furnace of the MIDREX technology. MIDREX technology which is the most important gas-based direct reduced iron (DRI) process in the world, includes reduction, transition and cooling zones. The reduction zone considered as

Influence of the reducing-gas distribution in the tuyere belt on the buildup in midrex furnaces
Steel in Translation, 2013The influence of the reducing-gas distribution in Midrex furnaces is investigated. The temperature of the tuyere belt in the furnace lining is studied experimentally, and blockage of the tuyeres by buildup is analyzed. The tuyeres are mainly blocked on account of the nonuniform reducing-gas distribution, which is associated with the temperature ...

Modeling MIDREX Based Process Configurations for Energy and Emission Analysis
steel research international, 2017A natural gas (NG) based MIDREX shaft model has been developed and validated for emission and energy estimation for crude steel production. The model is extended to hydrogen rich alternative fuels namely Coke Oven Gas (COG) and Syngas from coal gasification to predict emissions and energy for producing crude steel.

Parallel Multi-Physics Coupled Simulation of a Midrex Blast Furnace [PDF]
Proceedings of the International Conference on High Performance Computing in Asia-Pacific Region WorkshopsTraditional steelmaking is a major source of carbon dioxide emissions, but green steel production offers a sustainable alternative. Green steel is produced using hydrogen as a reducing agent instead of carbon monoxide, which results in only water vapour as a by-product.

Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2021
Heat loss is a leading cause of heightened global temperatures and carbon dioxide. The energy crisis has raised concerns on addressing heat recovery, especially in iron and steel industries. Iron and steel industries are consuming roughly 10 to 15 percent of the world’s energy.
