Ensemble models are adopted to estimate the sterile content of scraps arriving to the scrap yard. Feed‐forward neural networks are exploited to estimate steel composition and temperature after Ladle furnace. The models are validated on data from two steelworks very satisfactory results and are inherently transferable to other steelworks, as they are ...

Oxygen Refined Ferroalloys [PDF]
Successful in steelmaking, oxygen top-blowing techniques are not being employed for the refining of ferrochrome. This may be the beginning of the wide-spread use of oxygen in the ferroalloys industry.

A double intercritical annealing strategy is proposed to tailor the multiphase microstructure and mechanical response of a medium‐Mn steel. The treatment produces an ultrafine mixture of ferrite, martensite and multiple austenite populations with graded thermal and mechanical stability, formed through austenite reversion and controlled retransformation.

Emerging Technologies for Biobutanol Production via Syngas Fermentation
Biobutanol production from syngas is promising but limited by microbial energy conservation and gas–liquid mass transfer. This review integrates advances in cultivation control and bioreactor engineering with next‐generation biological tools including metabolic rewiring, co‐cultivation and chain elongation, and electro‐fermentation to enable carbon ...

Grinding chips of high‐alloyed steel are prepared to be admixed to a starting powder mixture for laser powder bed fusion. A three‐stage preparation is performed, including washing in acetone, magnetic separation, and ball milling. The addition of 30% of grinding chips to the powder mixture allows the fabrication of dense samples.

Modifying Effect of a New Boron-Barium Ferroalloy on the Wear Resistance of Low-Chromium Cast Iron
This paper presents the results of a study and analysis of the effect of modifying low-chromium hypoeutectic cast iron with a new boron–barium ferroalloy on its properties—wear resistance and impact resistance—in comparison with traditional boron- and ...
