ＩＦ钢在Ａｒ３温度以上终轧并在低温卷取时（６５０℃），热轧板的组织细小均匀，相对应的热轧板总延伸率很高（δ＞４３％）。受这个现象启发，作者提出了开发拉延用热轧ＩＦ钢的技术思路，并于１９９３年和武钢合作完成了该钢种的现场实验。通过冶炼使钢中Ｃ、Ｎ及杂质...
When IF steel is rolled over Ar3 temperature and coiled at low temperature (650 ℃), the microstructure of hot-rolled sheet is fine and uniform, and the corresponding total hot-rolled sheet elongation is high (δ> 43%). Inspired by this phenomenon, the author put forward the technical ideas for developing hot rolled IF steel for drawing and completed the field experiment of the steel with WISCO in 1993. Through the smelting of steel C, N and impurities ...
