Abstract (en)
[origin: EP2695953A1] A method is provided by which it is possible to easily add zinc to a molten steel in high yield. The method for adding zinc to a molten steel comprises supplying a composite oxide of Zn with Al and/or Si to a molten steel. The method for adding zinc to a molten steel may further includes supplying the oxide of Ca to the molten steel. The molten steel preferably is a molten steel for a hot work tool steel. A process for producing a zinc-containing steel is also provided in which the molten steel to which zinc has been added by the method for adding zinc to a molten steel is cast. The cast zinc-containing steel preferably has a Zn content of 0.001 mass% or higher.
