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 ...

Phosphorus-containing converter slag is a common waste in the iron and steel industry, has characteristics of high generation low secondary-utilization values; however, high-phosphorus content limits its ability to be recycled during steelmaking process. In this study, dephosphorization behavior by carbothermal reduction was studied through experiments thermodynamic calculations. The results sh...

The end-point control technology of basic oxygen furnace (BOF) steelmaking is a very important production process in the later stage smelting, and it has become research hotspot smelting industry. In this paper, carbon content temperature prediction models were established based on twin support vector regression (TSVR). order to ensure stability model, input variables model determined by using ...

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...

High electricity cost is the biggest challenge faced by steel industry in transitioning to hydrogen based steelmaking. A plant Norway could have access cheap, emission free electricity, high-quality iron ore, skilled manpower, and European market. An open-source model for conducting techno-economic assessment of a manufacturing plant, operating has been developed this work. Levelized production...

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.

Abstract Over the past few decades, steelmaking has reached its zenith in terms of annual productivity, and relevant processes have been developed over time to produce steel with maximum efficiency a shorter time. One prominent practices used extensively contemporary industries is Conarc Steelmaking Practice, which involves use electrical chemical Energy carry out melting decarburization respec...

This work investigates the melting behaviour of iron ore with calcium-based fluxes, including lime, limestone and basic oxygen furnace (BOF) steelmaking slag. With an aim to explore potential k...
