Safety soft sensor development for pilot‐scale ilmenite electric arc furnace using long short‐term memory‐based architecture

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Ilmenite electric arc furnaces (EAFs) are used for smelting titanium‐iron oxide ore at high temperatures generated by electrical arcs to produce titanium slag and pig iron. As these units are pushed to their limits, ensuring safe and reliable operation becomes challenging.

Crystallization of Cathode Active Material Precursors from Tartaric Acid Solution

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
This work investigates a novel approach for closing the gap between recycling and production of lithium‐ion battery cathode material. The new concept is based on antisolvent crystallization of metal carboxylates, which can be directly used as precursors in production of cathode material.

Influence of refining slag composition on nonmetallic inclusions in 38CrMoAl steel

Journal of Materials Research and Technology
To achieve economic transfer of calcium and accurate inclusion modification by utilizing the high basicity of slag instead of calcium treatment, the refining slag of 38CrMoAl steel was optimized through thermodynamic calculations in view of the large ...

The behavior of manganese in oxygen steelmaking [PDF]

, 2019
Manganese serves as an important alloying element in commercial grades of steel and high levels of Mn can improve the mechanical properties of steel. [1] The chemical behavior of Mn in Oxygen Steelmaking is complex because the element is readily oxidised

From Ice to Isolation: A geochemical reconstruction of the palaeoenvironmental evolution of Gairloch, NW Scotland (UK), since the Last Glacial Maximum

Journal of Quaternary Science, EarlyView.
ABSTRACT Complex relative sea‐level (RSL) changes are associated with the deglaciation of the British and Irish Ice Sheet (BIIS). Sediment archives from Loch Bad na h‐Achlaise, an isolation basin in NW Scotland, UK, span Late Glacial to Holocene time and record sea‐level change and ice proximity via a geochemical and biostratigraphic multiproxy ...

Modeling of the refractory's and slag's phase composition, the slag adjustment optimization and the ladle refining slag's stabilization

NOVYE OGNEUPORY (NEW REFRACTORIES), 2018
The modeling technique was proposed for the phase formation in the CaO‒MgO‒Al2O3‒SiO2‒FeO‒Fe2O3multicomponent oxide system. The technique can be used to predict the equilibrium phase composition for both the refractory and refractory-slag systems, as well as to modify the metallurgical slag's chemical composition, to extent the metallurgical unit's ...

Practice of Quick Desulphurization Technology for Low and Medium Carbon Steel Melting by 70 t EAF-LF

Teshugang, 2006
During 70 t EAF-LF melting steel 20MnSi,the desulphurizing refining time for average sulphur content in steel from 0.060% to 0.015% decreased to 20~30 min from original 30~45 min by adding lime 400~450 kg and synthetic slag 80~250kg,controlling EAF ...
