| titleOfInvention | How to prepare ladle slag |
| abstract | It is an object of the present invention to provide a ladle slag preparation method capable of shortening the preparation time of slag and improving the slag conversion rate of the injected material by adding a predetermined amount of calcium, magnesium, zinc and the like.n n n The present invention for achieving the above object, in the ladle slag preparation method for performing the secondary refining by putting the slag preparation material such as quicklime after tapping the molten steel firstly refined in the converter or electric furnace in the ladle. In the converter or electric furnace, calcium (Ca), magnesium, which volatilizes from molten steel after inputting preparations such as quicklime, aluminum, and deoxidizer at the time of tapping, tapping, after tapping, or the second refining process. (Mg) and zinc (Zn) are charged at 0.05 to 0.2 kg per tonne of molten steel to the molten steel in the ladle to form a ladle slag. In the present invention, CaO, Al 2 O 3 , CaF 2 and MgO are additionally mixed with calcium (Ca), magnesium (Mg) and zinc (Zn) to inject 0.05 to 0.2 kg per ton of molten steel into the molten steel in the ladle. To form a ladle slag. |
