TLDR
In this paper, the corrosion behavior of a pitch-bonded magnesia-carbon refractory by an Al 2 O 3 rich stainless steelmaking slag was investigated by rotating finger tests in a vacuum induction furnace at high temperature (>1650°C) and low oxygen partial pressure (1.5-4.3About:

Comparative evaluation investigation of slag corrosion on Al2O3 and MgO-Al2O3 refractories via experiments and thermodynamic simulations
TL;DR: In this paper, the authors investigated the corrosion behavior of two refractories with different compositions of virtual steelmaking slags (wt%CaO/wt%SiO 2 = 3.0-7.0, Al 2 O 3 : 18-35 Wt ) using laboratory experiments and FactSage thermodynamic modeling.

Melt corrosion of oxide and oxide–carbon refractories
William E. Lee,Shaowei Zhang +1 more
TL;DR: Theoretical models of these processes, as well as static (sessile drop, dipping, and crucible) and dynamic (rotating finger and rotary slag) experimental tests, along with their practical limitations are considered in this paper.

Principles of metal refining
TL;DR: In this article, the effect of dissolved impurity and inclusions on the mechanical properties of metal products is discussed. But the authors focus on the removal of inclusions and not on the physical properties of the metal.

Use of phase diagrams in studies of refractories corrosion
Shaowei Zhang,William E. Lee +1 more
TL;DR: In this article, the authors use phase diagrams to predict the conditions under which solid reaction product phases form at refractories/slag interfaces, which assists understanding of direct and indirect dissolution.

Significance of Oxidation-Reduction Reactions Within BOF Refractories
R. J. Leonard,R. H. Herron +1 more
TL;DR: The faster wear rate of pitch-bonded brick in high-wear areas of the BOF, as compared to burned impregnated brick, is attributed to the pronounced porous region created near the hot face when internal oxidation-reduction reactions consume the carbon bond as discussed by the authors.
