See full text

In a continuous casting method for casting aluminum-deoxidized molten stainless steel 1 by using a continuous casting apparatus 100 in which a long nozzle 3 extending into a tundish 101 is provided at a ladle 2, the molten stainless steel 1 is poured into the tundish 101 through the long nozzle 3, while the spout 3a of the long nozzle 3 is being immersed in the molten stainless steel 1 that has been poured, and the molten stainless steel 1 in the tundish 101 is poured into a casting mold 105. A TD powder 5 is sprayed so that the powder covers the surface of the molten stainless steel 1 in the tundish 101, and nitrogen gas is supplied around the molten stainless steel 1. A calcium-containing material is added to the molten stainless steel 1 in a state other than a state of retention in the tundish 101.
