| 摘 要： | 通过对电脉冲孕育（ＥＰＭ）处理和未经处理的Ｑ２３５钢连铸小方坯热加工后组织及性能的比较，研究了经ＥＰＭ自理后改善和细化了的凝固组织对热加工后组织和性能的影响，研究结果表明，经ＥＰＭ处理后的Ｑ２３５钢连铸小方坯铸造。热处理后的组织均匀，比未经处理钢的晶粒更为细小，晶粒尺寸由４０μ冯小到２０μｍ；提高了６．９％，值提高了１０％。

| Abstract: | Compared the structure and property of Q235 continuous casting bloom by EPM treating with no-treating after heating working, the influence of structure and prop- erty of heating working with improved and fined casting structure by EPM treating have been researched. The results shown that the structure of heating working by EPM treating is more even, and the crystal is finer than no-treating. The increases 6.9%, and increases 100%. |
