steelmaking slag of mobarakeh steel company (msc) has a high iron content which makes it unsuitable for conventional slag recovery; as in cement industries. on the other hand, eaf slag in this company is almost free of zinc because of using more than 90 percent dri in the charge. therefore, removal or recovery of iron from the slag can be a suitable solution to slag recovery in this company. in...

these days, limited energy resources, and also the cost of investment in new and renewable energy is very costly and uneconomical. in the industrial sector, especially energy-intensive industries such as steel, finding appropriate solutions to update the technology, production and reduce energy consumption in this sector is very important. the main aim of this study is the identification and ra...

Basic Oxygen Furnace (BOF) steelmaking is, worldwide, the most frequently applied process. According to world steel organization statistical report, 2021, it saw a total production share of 73.2%, or 1371.2 million tons per year in 2020. The rest is produced Electric Arc (EAF)-based mills (26.3%), and only very few open-hearth induction furnace-based mills. BOF technology remains leading based ...

Recycling phosphorus from phosphorus-containing wastes and byproducts is a promising secondary resource. Steelmaking slag generated in large quantities as byproduct of the iron steelmaking industry, contains that could be possible Phosphorus can extracted into aqueous solution; however, concentration generally lower than other elements, causing problem for recovery. In this study, bipolar membr...

Steelmaking in the electric arc furnace (EAF), either scrap-based or based on hydrogen direct reduced iron, will future contribute substantially to reduction of CO2 emissions iron and steel industry. However, there still be need introduce carbon into EAF process carburize create foaming slag improve energy efficiency melting process. So, reach emission goals set around world, it necessary subst...

In article 2200532, Liu and co-workers illustrate study the hydrodynamic interaction between top-blowing supersonic jets bottom-blowing plumes during top bottom combined blowing converter steelmaking process. Four tuyere arrangement cases are designed considering influence of cavity morphology.
