Method of producing molten aluminum-killed steel for thin steel sheet |
摘要 |
In a method of producing a molten aluminum-killed steel for forming a thin steel sheet, molten steel tapped from a converter is decarburized to a predetermined carbon concentration by using a vacuum degasser, and Al is added to the molten steel in the vacuum degasser to deoxidize the molten steel. A material containing metallic Ca is then added to the molten steel to produce a Ca content of about 0.0005 to 0.005 wt %, and to satisfy [%Ca]x[%S]</= about 2x1 0-5. Thereafter, degassing is performed on the molten steel.
