Investigation into Hydration Resistance of CaO-Containing Materials

Abstract:

In order to develop an ideal material for the nozzle used in steel continuous casting process, the hydration resistance of some CaO-containing complex oxides and CaO-NiO solid solutions were investigated systematically. The hydration resistance of the complex oxides was CT >CZ>CS>CF>CB3BTB2 B>CB2BS>>CB2BF>CB3BA>CAB2B>CaO. CT should be a promising material for the nozzle. A large number of fine secondary-NiOss particles were separated from the CaOss crystal grains in CaO-NiO solid solution and improved the hydration resistance.
