Abstract
PURPOSE: To prevent the occurrence of internal cracking of a solidified shell during unbending and straightening by forming at least the inside surface side of the solidified shell of a cast ingot into the cubic system structure and performing unbending and straightening.
CONSTITUTION: In a rotary ring type continuous casting method, the solidified structure of a brittle region in the solidified shell during straightening of bending is formed into the cubic system, and more preferably, the columnar crystal length from the surface of the cast ingot is kept within about 1/2 the thickness of the solidified shell. To obtain the cubic system structure, in the case of steel, methods such as lowering of casting temp., internal cooling of molten steel by charging of a cooling material, for example, steel grains, into the molten steel prior to teeming into a mold and the molten steel in the mold and inoculating or electromagnetic stirring of the molten steel in the mold are used.
