Manjhi, S P and Ramachandran, N and Nalla, R N and Bajpai, M K and Tripathi, P K (1996) Mathematical model for predicting solidification and cooling of steel inside mould and in air. In: Proceedings of the National Seminar on Computer Applications in Materials & Metallurgical Laboratory, Dec. 10-11, 1996, NML, Jamshedpur.
A two-dimensional mathematical model has been developed to describe the solidification and cooling of steel inside the mould after teeming and in the air after stripping. Partial differential equations describing the processes have been discretized using control volume approach. The discretization equations obtained are of Tri-diagonal matrix form, which have been solved using well known Tri-diagonal matrix algorithm (TDMA) and Alternate direction implicit (ADI) solver. The model has been validated by measuring surface temperatures of mould and ingot using Infrared thermo-vision scanner. This is then used to compute charging temperature and solidification status of ingot as function of track time and type of ingot.
