摘要
通过对衡阳钢管厂２０钢水平连铸坯的［Ｐ］、［Ｓ］、Ｍｎ／Ｓ及其对应的中间裂纹统计，得出：［Ｐ］、［Ｓ］、Ｍｎ／Ｓ对中间裂纹有较大影响，随［Ｐ］的增加，中间裂纹的敏感性增大；随［Ｓ］的增加，敏感性增大；随Ｍｎ／Ｓ增加，敏感性变小。
From the statistics of ,,Mn/S and the corresponding inner capillary cracks in 20 steel horizontal continuous cast billets,it is concluded that ,and Mn/S have great influence on inner capillary cracking,the inner capillary cracking sensibility increases with the increase ofand ,and decreases with the increase of Mn/S
