Numerical Simulation of Heat Transport from the Electric Arc Furnace to the Heat Recovery System
Communications, 2016 The paper presents a numerical model of heat transport from melting charge of the electric arc furnace designed for ferroalloy production, into a cooled roof of the electric arc furnace from which waste heat is led to the heating system of a company. The

steel research international, EarlyView.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]
JOM, 1961 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.

steel research international, EarlyView.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.

Production of borbarium ferroalloy
Metalurgija, 2020 In the present work, it was considered expedient to organize the production of binary borbaric ferroalloy. The simultaneous presence in it of barium and boron, known as an effective micro-alloying element, should provide it with a high demand for industry.
