| Abstract: | In the established model,
the cooling differences are considered between the surface of inner radius and that of
outer radius, and in the transverse direction of thin slab. And the conception for the
effective coefficient of spraying water in continuous casting is firstly put forward.
According to different casting speeds and different cooling zones, different time step
lengths are adopted. In this model the heat transfer differences are thought over among
vertical and curved zones, wide and narrow surfaces an well as angular zone of mould. The
method of the corrected equivalent specific heat is used to deal with latent heat. The
influence of forced convection is considered on heat transfer. Therefore, the model has
higher accuracy and is consistent with the practice. |
