| 摘 要： | 在150 t转炉-出钢脱氧合金化-钢包底吹氩-LF精炼-72.0~92.5 mm板坯连铸-2.75~5.50 mm带材连轧工艺生产中,试验了在转炉出钢时使用Fe-Al-Mg(2.5%Mg,60%Al)脱氧剂对含0.17~0.22C的SS400钢薄板坯纯净度和力学性能的影响。结果表明,用Fe-Al-Mg复合脱氧剂所生产的板材中的夹杂物数量(硅酸盐夹杂0.5级)和尺寸较用Fe-Al脱氧剂生产的板材中夹杂物数量(硅酸盐夹杂3.0级)和尺寸大幅度降低;前者抗拉强度较后者提高10~20 MPa。

| Abstract: | The effect of using Fe-Al-Mg(2.5%Mg,60%Al)deoxidizer during converter tapping on cleanliness and mechanical properties of thin slab of 0. 17~0.22C SS400 steel produced by 150 t converter - LF bottom argon blowing-LF refning-72.0~92.5 mm slab concasting-2.75～5.50 mm strip continuous rolling process has been tested. The results showed that the amount(silicate inclusions rating 0.5 units)and size of inclusion in steel sheet produced by Fe-Mg-Al deoxidizer were obviously lower than the amount(silicate inclusions rating 3.0 units)and size of inclusion in steel sheet produced by Fe-Al deoxidizer and the tensile strength of the former was 10~20 MPa higher than that of the later. |
