Sažetak
In this paper, the effect of exothermic riser on ingot solidification is studied by numerical simulation. Through the study, it is concluded that the combustion of exothermic risers delayed the solidification of steel in riser, and the solidification time increased significantly, extending about 8 143 / s. In the later stage of solidification, the temperature isotherm of the ingot is smoother than that of the ordinary ingot, making the angle of the solidification front larger, which is conducive to feed. The shrinkage of the ingot with heat riser is better than that of the common ingot. The shrinkage above 10 % of the ingot is almost not found in the ingot with exothermic riser, and the shrinkage of the ingot is mainly concentrated above the riser line. And it obviously improves the internal quality of the ingot.
