A model of water-spray cooling effect on a continuous casting process

摘要

The intention of this study is to give an idea about the influence of water-spray cooling on the solidification process of the liquid metal which enables to locate the shear region. The effect of spray heat transfer coefficient ( h _(spray)) during the liquid-to-solid transition through the cooled zone temperature and the metal latent heat of solidification are highlighted. A gray iron continuous casting process subjected to water-sprays cooling was simulated using the commercial code COMSOL MULTIPHYSICS 5.2. The obtained results show the great influence of h _(spray)on the location of transition region as well as the relationship between h _(spray), wall outer temperature, latent heat dissipation, and the solidification time.
