Abstract

본 발명에 따라 제조되는 칼슘처리한 황 첨가강재는 기계 구조용 탄소강재나 냉간 압조용 강재로 샤프트, 쇼크압소바(shock absorber)등 자동차 부품에 사용된다.Calcium-treated sulfur-added steel produced according to the present invention is used in automotive parts such as shafts, shock absorbers, etc. as carbon structural steel or cold rolling steel.

본 칼슘처리한 황 첨가강의 제조방법은 전로에서 정련이 종료된 용강에 대해 염기도 (CaO/SiO2)가 6~7로, CaO/Al2O3가 2로 되도록 래들의 슬래그 조성을 조정하고, 알루미늄 함량은 강재가 요구하는 범위내에서 하한으로 조정하고, 황 함량은 0.010% 이하로 조정하는 단계와, 상기 성분 조정된 용강에 칼슘처리하는 단계와, 상기 칼슘 처리된 용강에 황 와이어(Sulfur Wire)를 첨가하는 것을 특징으로 한다.The method of manufacturing the calcium-treated sulfur-added steel is to adjust the slag composition of the ladle so that the basicity (CaO / SiO 2 ) is 6-7 and CaO / Al 2 O 3 is 2 with respect to the molten steel after the refining in the converter. The content is adjusted to the lower limit within the range required by the steel, the sulfur content is adjusted to 0.010% or less, the step of calcium treatment of the component adjusted molten steel, sulfur wire in the calcium treated molten steel (Sulfur Wire) It is characterized by the addition of.

전로에서 정련이 종료된 용강에 대해 염기도 (CaO/SiO2)가 6~7로, CaO/Al2O3가 2로 되도록 래들의 슬래그 조성을 조정하고, 알루미늄 함량은 강재가 요구하는 범위내에서 하한으로 조정하고, 황 함량은 0.010% 이하로 조정하는 단계와, 상기 성분 조정된 용강에 칼슘처리하는 단계와, 상기 칼슘 처리된 용강에 황 와이어(Sulfur Wire)를 첨가하는 것을 특징으로 하는 칼슘 처리된 황 첨가강의 제조방법.The slag composition of the ladle is adjusted so that the basicity (CaO / SiO 2 ) is 6-7 and CaO / Al 2 O 3 is 2 for the molten steel after the refining in the converter, and the aluminum content is the lower limit within the range required by the steel. And the sulfur content is adjusted to 0.010% or less, calcium treatment to the component-controlled molten steel, and calcium wire, characterized in that sulfur wire is added to the calcium-treated molten steel. Method for producing sulfur added steel. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
