Web1 de jul. de 2012 · In high speed continuous casting of peritectic steel slabs, mold fluxes with high basicity are required for less surface defect product. However, the basicity of remaining liquid slag film tends to decrease in casting process because of the crystallization of 3CaO · 2SiO 2 · CaF 2.Thus, a way is put forward to improve mold fluxes properties … Web1 de jan. de 2013 · Basic fluxes with higher basicity index (BI > 1.5) generally are used due to its ability to provide significant mechanical properties.
Web11 de abr. de 2024 · Whereas, CaO was found to give basicity of 0.7533 mmol g −1 with peak maxima at 420 °C, Cerium oxide showed basicity of 0.0867 mmol g −1 with peak maxima at 290 °C and BaO showed highest basicity of 0.9911 mmol g −1. The CaO and BaO showed maximum desorption in the higher temperature range. WebBasicity is a major factor in determining the molecular species distribution; low-basicity favors low molecular weight species and high-basicity favors high molecular weight species. Temperature and concentration also effect the molecular species distribution but in less predictable ways.
