Mass transfer behaviour of Mg in low carbon aluminium killed steel during LF refining
Ironmaking & Steelmaking, 2016Inclusions containing Mg existed in low carbon aluminium killed steel even though Mg is not added during LF treatment. To investigate the mass transfer mechanism of Mg in low carbon aluminium killed steel, both industrial practice and kinetic calculations were carried out in the present work.

Steel plate cold common (SPCC) is a Al-killed steel with Ca-treatment. The control of Al2O3 indusion into low melting point liquid region is beneficial for indusion removal, cast-ability promotion and defects reduction during rolling. Thus it is essential to understand steel-indusion equilibrium since indusion composition is determined by composition ...

Inclusions evolution during the LF refining process of 439 ultra-pure ferritic stainless steel
Metallurgical Research & Technology, 2019The morphology, composition, size, and number of inclusions in 439 ultra-pure ferritic stainless steel samples were analyzed using an automatic scanning electron microscope combined with an energy-dispersive X-ray spectrometer. In addition, the appropriate contents of titanium, aluminum, and calcium were analyzed through the coupling of thermodynamics ...

[Determination of LF-VD refining furnace slag by X ray fluorescence spectrometry].
Guang pu xue yu guang pu fen xi = Guang pu, 2010Eight components, i.e. TFe, CaO, MgO, Al2O3, SiO2, TiO2, MnO and P2O5 in refining furnace slag were determined by X ray fluorescence spectrometer. Because the content of CaO was high, the authors selected 12 national and departmental grade slag standard samples and prepared a series of synthetic standard samples by adding spectrally pure reagents to ...

Study on Experiment and Mechanism of Bottom Blowing CO2 During the LF Refining Process
steel research international, 2013In order to explore the metallurgical behavior and mechanism of bottom blowing CO2 in ladle furnace (LF), CO2 was introduced in the LF refining process. The kinetics and thermodynamics of bottom blowing CO2 were investigated and several mathematical models for kinetic study were established.
