Study of Lime Dissolution Under Forced Convection

  • Tengfei Deng

Dissolution of different CaO cubes under force convection in liquid CaO-“FeO”-SiO2 slag was studied at 1873 K (1600 °C). A linear relationship between normalized lengths and time was obtained after the experiment. It was evidently observed that the removal of the interface layer(s) including 2CaO·SiO2 by shear stress was the main mechanism for the dissolution. A stirring rate of approximately 100 rpm was found to be efficient to remove the interface layer(s). The limes with different structures had different dissolution rates.
