Abstract
In a continuous casting method for casting aluminum-deoxidized molten stainless steelby using a continuous casting apparatusin which a long nozzleextending into a tundishis provided at a ladle, the molten stainless steelis poured into the tundishthrough the long nozzle, while the spoutof the long nozzleis being immersed in the molten stainless steelthat has been poured, and the molten stainless steelin the tundishis poured into a casting mold. A TD powderis sprayed so that the powder covers the surface of the molten stainless steelin the tundish, and nitrogen gas is supplied around the molten stainless steel. A calcium-containing material is added to the molten stainless steelin a state other than a state of retention in the tundish
