Title: Continuous casting method for clad ingot
Inventor: IWATA KATSUYOSHI
IPC: B22D11/115
Filed: 1985-06-05
Abstract: PURPOSE:To obtain continuously a clad ingot without requiring a base metal and to make possible the optional setting of a cladding ratio and the concn. gradient of a negative segregation layer by forming the negative segregation layer having different component concns. by electromagnetic stirring in the process for solidification of one kind of molten steel. CONSTITUTION:The unsolidified steel 15 is stirred by an electromagnetic stirrer 14 in the stage when the solidified shell 13 of the ingot 12 drawn from a mold 11 grows to a prescribed wall thickness. The thickened steel stagnating in the region (between secondary dendrites) near the shell 13 is thereby migrated toward the centripetal direction and the negative segregation is positively formed. The thickness (t) of the shell 13 and the thickness T of the negative segregation layer 16 are set by adjusting the installation position of the stirrer 14, by which the cladding ratio [t/(T+t)] is controlled. The concn. gradient of the negative segregation layer 16 is controlled by setting the stirring intensity of the stirrer 14.
