Abstract
In a continuous casting method for casting an 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 through the long nozzle 3 into the tundish 101, while immersing a spout 3a into the poured molten stainless steel 1, 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, a nitrogen gas is supplied around the molten stainless steel 1, and a calcium-containing material is added to the molten stainless steel 1 in the tundish 101. The surface of the molten stainless steel 1 after casting is ground.
