Title: Curved type continuous casting method of steel
Inventor: MATSUOKA KATSUHIKO
IPC: B22D11/10
Filed: 1982-01-08
Abstract: PURPOSE:To perform curved type continuous casting of steel safely and effeciently by mounting a metal which receives an outflow melt to the top of an ingot at the end of casting and drawing the ingot. CONSTITUTION:In curved type continuous casting installation, a metal 11 for receiving an outflow melt having a receiving member 12 is mounted to the top part 6a of an ingot located in a casting mold 5 at the point of the time when casting ends, and is drawn. When the top part 6a arrives at a curved part, a peak surface 6a3 inclines and the static pressure by the unsolidified molten metal in an ingot 6 is exerted upon a solidified shell 6a2 on the top surface, by which the shell 6a2 is ruptured and the unsoldified melt 100 is streamed out. This outflow melt 100 is received in the receiving member 12 of the metal 11. Thus, the continuous casting work is continued without decreasing the drawing speed.
