| 摘 要： | 针对42CrMo钢板淬火开裂的问题，分析认为其原因是连铸坯中心偏析严重并伴随有夹杂物所致。通过优化化学成分设计、采用洁净钢冶炼、连铸过程投入电磁搅拌等措施，使42CrMo钢铸坯低倍质量达到C类0.5级；通过辊压式热处理线进行热处理，保证了风电用偏航导向板42CrMo整板调质交货，整板性能满足“GB/T 3077”标准中试样调质热处理试验性能要求，达到客户技术要求。

| Abstract: | U-shaped control model for coiling temperature was put forward to improve the high strength and low plasticity of head and tail of hot rolled strip. The properties contrast of strips by U- shaped model and common model were described, and the good effects of U-shaped control moolel were very obvious. |
