| Abstract: | The molten mould flux in a continuous casting process flows into the gap between the mould and the solidifying shell of slab and plays a role in lubrication. A mathematical model describing lubrication due to mould flux was established according to the Navier Stokes equation and some simplifying presumptions. By the mathematical model and the law of solidification, it is able to predict the effect of physical properties of the mould flux and process parameters of the continuous casting process on thickness of lubrication film, consumption of mould flux,resistance to pulling slab and heat transfer to the mould. |
