AI Technical Summary
Existing large billet crystallizers often have crack defects at the corners of the cast billet, and uneven cooling at the corners leads to coarse microstructure at the corners, affecting the quality of the cast billet and the service life of the crystallizer.
By establishing a three-dimensional instantaneous thermal/mechanical coupling calculation model, the narrow face, wide face, and corner taper of the copper tube are designed. Non-uniform mesh generation and birth/death element calculation are adopted to optimize the inner cavity shape of the copper tube and realize the gradual compensation of the inner cavity of the copper tube along the height direction, so as to ensure uniform growth and heat transfer of the billet in the crystallizer.
It effectively eliminates "hot spots" at the corners of the billet, reduces corner cracks, extends the service life of the copper tubes in the crystallizer, and improves the surface quality of the billet.
