Design and Fluidity Research of a New Tundish Flux for Rare Earth Steel

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

“…A similar method was reported in our previous reports. [ 16–18 ] The samples were melted at 1550 °C for 2 h to reach homogenization, and then the samples were quenched with ice water rapidly to obtain the glassy phase. Finally, the premelted slag (about 1.5 g) was mixed with alcohol as the binder in an agate mortar and then pressed into a cube sample (5 mm× 5 mm × 5 mm) under a load of 5 MPa for 5 min.…”

“…A similar method has been reported in our previous reports. [16][17][18] The roughness (Ra) of the CeAlO 3 substrate was analyzed by 3D Roughness Reconstruction software of SEM (Phenom Pro X, The Netherlands). The porosity of the CeAlO 3 substrate was calculated by ImageJ.…”

“…To reduce the slag‐steel reaction of rare earth steel, the authors designed the CaO‐Al 2 O 3 ‐Ce 2 O 3 ‐based slag. [ 16–18 ] Therefore, the dissolution mechanism of CeAlO 3 in the CaO‐Al 2 O 3 ‐Ce 2 O 3 ‐based slag was investigated at 1550 °C in the current study. The effect of w (CaO)/ w (Al 2 O 3 ) on dissolution behavior was discussed.…”
