- The results indicate that the central carbon segregation of billets is aggravated with the increase of permeability due to enlarged SDAS. 随搅拌电流增大,二次枝晶间距明显减小。随二次枝晶臂间距增大,渗透率增加,造成铸坯中心碳偏析加重。
- Using these results, it can be concluded that slab stack cooling can promote the diffusion of hydrogen, but weakly affect central carbon segregation. 根据氢和碳的元素扩散规律,可知板坯堆冷工艺可以促使氢的扩散,但对中心碳偏析影响不大。
- It was shown that with the M-EMS intensity increase, the central carbon segregation in billets decreased, but the negative segregation near the edge in billets became worse. 在结晶器电磁搅拌条件下,随着二冷比水量增大,中心碳偏析减小;
- Central Carbon Segregation 中心碳偏析
- Both experiments and production practice have showed that the application of static soft reduction technology can decrease carbon segregation and improve looseness state in billet central area. 试验和生产应用表明,静态轻压下技术在高碳连铸方坯生产中应用,可降低铸坯中心碳偏析,改善铸坯中心疏松状况。
- Residual stress, carbon segregation and acid cleaning after cold drawing played decisive roles in the hydrogen-induced cracking. 螺杆心部具有高的残余应力、较严重的碳偏析及拉拔后的酸洗为螺杆心部出现HIC空洞提供了条件。
- Under M-EMS condition, with the increase of secondary cooling water flow rate and the decrease of casting speed, tundish superheat and carbon content, the center carbon segregation was improved. 随拉速、中间包钢水过热度和钢中碳含量增加,中心碳偏析加重。
- Can generate is relatively stable carbon-left groups and the response of vulnerable SN1, central carbon atom space hampered the response of small-prone SN2. 能生成相对稳定的正碳离子和离去基团的反应物容易发生SN1,中心碳原子空间阻碍小的反应物容易发生SN2 。
