CONTINUOUSLY CAST INGOT Russian patent published in 1997 - IPC

FIELD: metallurgy. SUBSTANCE: ingot has narrow faces 1, transition faces 2 and wide faces 3. Angle of inclination of transition faces 2 to wide face amounts to 120-150 deg, and ratio of distance between narrow faces 1 to distance between wide faces is 1.0-1.2. Width of transition face 2 equals 0.04-0.08 of total width of narrow and wide faces 1 and 3. EFFECT: reduced number of ingots internal cracks in production of ingots with cross-section in excess of 500 sq.cm due to reduced internal stress in region of corners of ingot and middle part of transition face. 2 dwg
