连续铸造方法
摘要：
在使用浇桶(2)设有延伸至中间包(101)内的长喷嘴(3)的连续铸造装置(100)来铸造进行了铝脱氧的不锈钢水(1)的连续铸造方法中，一边使浇注口(3a)浸渍于注入的不锈钢水(1)，一边将不锈钢水(1)通过长喷嘴(3)注入中间包(101)内，并且将中间包(101)内的不锈钢水(1)注入铸模(105)。进而，以覆盖中间包(101)内的不锈钢水(1)的表面的方式喷洒TD覆盖剂(5)，向不锈钢水(1)的周围供给氮气，向中间包(101)内的不锈钢水(1)添加含钙物。然后，对铸造后的不锈钢水(1)的表面进行磨削。
摘要（英）：

In a continuous casting method for casting aluminum-deoxidized molten stainless steel (1) using a continuous casting apparatus (100) in which a long nozzle (3) that extends into a tundish (101) is provided on a ladle (2), in addition to pouring the molten stainless steel (1) into the tundish (101) through the long nozzle (3) while immersing the spout (3a) in the molten stainless steel (1) that has been poured, the molten stainless steel (1) in the tundish (101) is poured into a mold (105). TD powder (5) is sprinkled so as to cover the surface of the molten stainless steel (1) in the tundish (101), nitrogen gas is supplied around the molten stainless steel (1), and a calcium-containing substance is added to the molten stainless steel (1) in the tundish (101). The surface of the molten stainless steel (1) after casting is ground.
