| 摘 要： | 在普通热轧机上利用累积叠轧焊工艺对普碳钢Q235进行了实验研究,重点研究了压下量(最大压下量98%)、循环轧制次数等工艺参数对Q235钢组织及性能的影响规律.结果表明:在普通热轧机上应用累积叠轧焊工艺对同种材料进行焊合,不仅可以获得连续、均匀的结合组织,而且使Q235钢的组织得到明显的细化,夹杂物分布更加均匀,材料的强度大幅度提高,抗拉强度达800MPa以上.

| Abstract: | Industrial experiments of Q235 plain carbon steel by Accumulitive Roll-Bonding (ARB) process were carried out. The effects of deformation temperature, reduction (the max reduction 98%) and cyclic roling pass on the microstructure and mechanical properties of the steel were investigated. The results showed that a steel with ultrafine grains and higher mechanical properties could be obtained on a plain hot rolling mill by ARB process. It was also proved that the interfacial microstructure was continuous and homogeneous because of the same material rolling. |
