Title: Continuous casting method
Inventor: TOKI MASAHIRO
IPC: B22D11/10
Filed: 2001-05-11
Abstract: PROBLEM TO BE SOLVED: To improve entrapment of powder caused by inversion flow, into small amount by shallowing dipping depth of spouting flow of molten steel from a straight nozzle, in the case of casting the molten steel at high speed into a small cross sectional mold provided with a coil for electromagnetic stirring.
