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...

There is a growing drive within the steel industry to increase scrap usage in Blast Furnace (BF)-Basic Oxygen (BOF) integrated route and extend scrap-based Electric Arc (EAF) for production due resultant reduced energy costs CO2 emissions abundant supply UK. In general, may contain high levels of undesirable residual elements, which have pronounced effects on casting process production. This ar...

Basic Oxygen Furnace Slag (BOF), as alternatives for aggregate in asphalt pavement construction, is beneficial to the environment by reducing land occupation and resource consumption. However, quantitative effects on energy consumption emissions reduction remains poorly understood due unavailability of local life cycle inventory. Therefore, its LCI needs be built accounting properties BOF terms...

The European steel industry produces about 70 million tons/year of by the electric arc furnace (EAF). slag consists 15% weight produced steel, thus from perspective circular economy, it has a high potential as co-product. This research aims to assess an innovative reuse EAF filler in different polymer matrixes: thermoplastic (polypropylene), thermosetting (epoxy resin), elastomeric (nitrile but...

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 ...

The effect of the curing in a carbonated ambient of the solids obtained after the stabilization/solidification (S/S) of metallurgical waste using geopolymerization technology is described in this paper. The electric arc furnace (EAF) dust used to stabilize contains hazardous metals such as Pb, Cd, Cr or Zn. Different geopolymeric agents as potassium hydroxide, potassium silicate, metakaolin and...

The electric arc furnace (EAF) has the potential to significantly contribute decarbonization of iron and steel industry. However, during EAF steelmaking, carbon still needs be injected into molten slag initiate foaming, which is beneficial energy efficiency protection furnace. To move away from fossil carbon, biocarbon gained attention as an injection agent. In this study, two biochar candidate...

Temperature control is the primary concern during design and construction process of mass concrete structures. As production has an enormous negative environmental impact, development green concretes will eventually become as important thermal characteristics. Therefore, this paper investigates use Electric Arc Furnace (EAF) steel slag aggregate for partial replacement natural in concrete. The ...
