To solve the surface sliver defect of threated steel, the macro morphology and micro composition of threated steel were detected by SEM scanning electron microscope and energy spectrum analyzer. The results showed that there were unilateral sliver defects of different sizes at the longitudinal and transverse ribs of the threated steel. The irregular inclusions of Al2O3, SiO2 and Al2O3-SiO2 were detected at the cross section of the sliver defects, with sizes ranging from 40~120 μm. These non-metallic inclusions caused a deterioration in the local plasticity of the threaded steel ingot, leading to the formation of cracks. As the rolling process progressed, these cracks gradually expanded and ultimately resulted in sliver defects. By implementing measures such as reducing the oxygen content at the converter endpoint and enhancing the air-tightness during pouring, the average oxygen content of the molten steel in the tundish was reduced to 25ppm. Consequently, the incidence rate of surface sliver defects in hot - rolled products decreased from 2.7% to 1.5%, effectively preventing the occurrence of sliver defects.

为解决螺纹钢表面翘皮的缺陷问题,利用SEM扫描电子显微镜和能谱分析仪对螺纹钢的宏观形貌和缺陷处微观成分进行了分析与检测。结果表明:螺纹钢纵肋和横肋处存在大小不一的单侧翘皮缺陷;在翘皮断面处检测到Al2O3-SiO2、Al2O3及SiO2类型不规则状夹杂物,其尺寸在40~120 μm。这些非金属夹杂物导致螺纹钢锭局部塑性变差,进而产生裂纹,随着轧制过程的进行,这些裂纹逐渐扩展并最终形成翘皮缺陷。采用降低转炉终点氧含量、加强浇注气密性等措施将中间包钢水的氧平均含量降至25ppm,热轧件表面翘皮缺陷的发生率从2.7%下降到1.5%,有效地减少了翘皮缺陷的发生。

为解决螺纹钢表面翘皮的缺陷问题,利用SEM扫描电子显微镜和能谱分析仪对螺纹钢的宏观形貌和缺陷处微观成分进行了分析与检测。结果表明:螺纹钢纵肋和横肋处存在大小不一的单侧翘皮缺陷;在翘皮断面处检测到Al2O3-SiO2、Al2O3及SiO2类型不规则状夹杂物,其尺寸在40~120 μm。这些非金属夹杂物导致螺纹钢锭局部塑性变差,进而产生裂纹,随着轧制过程的进行,这些裂纹逐渐扩展并最终形成翘皮缺陷。采用降低转炉终点氧含量、加强浇注气密性等措施将中间包钢水的氧平均含量降至25ppm,热轧件表面翘皮缺陷的发生率从2.7%下降到1.5%,有效地减少了翘皮缺陷的发生。

To solve the surface sliver defect of threated steel, the macro morphology and micro composition of threated steel were detected by SEM scanning electron microscope and energy spectrum analyzer. The results showed that there were unilateral sliver defects of different sizes at the longitudinal and transverse ribs of the threated steel. The irregular inclusions of Al2O3, SiO2 and Al2O3-SiO2 were detected at the cross section of the sliver defects, with sizes ranging from 40~120 μm. These non-metallic inclusions caused a deterioration in the local plasticity of the threaded steel ingot, leading to the formation of cracks. As the rolling process progressed, these cracks gradually expanded and ultimately resulted in sliver defects. By implementing measures such as reducing the oxygen content at the converter endpoint and enhancing the air-tightness during pouring, the average oxygen content of the molten steel in the tundish was reduced to 25ppm. Consequently, the incidence rate of surface sliver defects in hot - rolled products decreased from 2.7% to 1.5%, effectively preventing the occurrence of sliver defects.
