Wetting and corrosion behavior of MgO substrates by CaO–Al2O3–SiO2–(MgO) molten slags

Effect of Al Content in Steel on Interfacial Interaction between Molten Steel and MgO Substrate

“…The area percentage of interaction between the molten steel and the substrate can be obtained from the calculation of the red area in Figure 4–8a, [ 5 ] as shown in Figure 9 . With the increase of w [Al] from 0.002% to 0.831%, the interaction area percentage increased from 5.79% to 8.87% first, and then decreased to 3.42%.…”

“…Our previous work has shown that MM aggregate also has a better corrosion resistance to slag than the fused magnesia. [4,5] It is well known that both molten slag and molten steel can corrode refractories in metallurgical processes, which not only shortens the service life of refractories, but also forms inclusions that affect the quality of steel. So far, there are few studies about the interaction between MM aggregate and molten steel, so it is necessary to study the interaction between them.…”

Insight into Interaction Behavior of CeAlO3 Substrate and CaO‐Al2O3‐Based Slag

“…From Figure 12 d, the thickness of the penetration layer increased with w (CaO)/ w (Al 2 O 3 ) in the slag. The thickness of penetration can be expressed by Lucas–Washburn's equation, as shown in Equation (1) [ 23,24 ] . where l is the thickness (m), r is the pore size of the substrate (m), θ is the contact angle (deg), η is the slag viscosity (Pa s), γ is the surface tension (N m −1 ), and t is the dissolution time (s).…”

Method of raw materials selection for production of the MgO‐C bricks of comparable properties using PCA and K‐medoids

“…Corrosion resistance of various MgO-C refractories was investigated too. Authors [17][18][19][20][21][22][23] described the corrosion mechanism of MgO-C materials in different conditions. All mentioned researches pointed out that chemical purity of MgO-C bricks magnesia part is crucial for providing excellent corrosion resistance.…”
