3 ≤23%을 포함하게 된다. RH 정련으로 탈탄이 종료되자마자, 용융된 강은 탈산화되고 Si-Fe, Al-Fe 또는 Mn-Fe를 사용하여 합금화되고, 심도 탈황된다. 탈황의 비율은 50%-75%이다.
The invention relates to a method for controlling the titanium content in the ultra-low carbon killed steel. Steel C≤0.005%, Si: 0.1 ~ 3.4%, Mn: 0.1 ~ 0.5%, P≤0.2%, S≤0.002%, Al: 0 ~ 1.2%, N≤0.005%, Ti≤0.0015% (weight% ), and a small amount of Fe as impurities and the remainder. When steel would have been obtained by the pre-processing, refining, RH refining and casting the molten steel, decarburization is completed to the RH refining by addition of Al-Ca-based modification of the slag to the top of the sand, the top of the slag is below T.Fe It will include ≥5% and Al

3 ≤23%. As soon as the end of the decarburization to the RH refining, and the molten steel is alloyed with a de-oxidized Si-Fe, Al-Fe-Mn or Fe, it is desulfurized field. Rate of desulfurization is 50-75%.
