Title: Method for preventing channeling of molten metal in continuous casting mold
Inventor: YAMAZAKI HISAO
IPC: B22D11/116
Filed: 1994-03-29
Abstract: PURPOSE:To uniformize molten steel flow and to reduce a product defect by conducting DC current in the vertical direction interposing spouted molten metal, at the time of executing continuous casting while impressing static magnetic field at the height of a spouting hole from which the molten metal is discharged to a mold through a multiholed nozzle. CONSTITUTION:The molten metal is spouted into the mold from the multiholed nozzle 1 with the lower end of the nozzle closed and having plural spouting holes 5 confronted with each other on the lower part of the side wall of the nozzle 1. At the time of continuously casting this molten metal while impressing the static magnetic field 9 to the position including this spouting hole, the DC current 3 is conducted vertically to at least one of the spouting hole 5 interposing the spouted molten metal 13. By this method, even if local channeling is developed in the flow of the molten metal 13 in the continuous casting mold due to the clogging of the nozzle, etc., the spouting velocity from each spouting hole 5 can individually be controlled. Further, since the local channeling of the molten metal 13 in the mold is detected and the direction and the intensity of the DC current 3 at each spouting hole are changed based on this detected value, the channeling is more effectively controlled.
