| 摘 要： | 以Q235B和Q345R为例,分析了连铸坯和电渣重熔钢锭的内部质量情况,并在实验室条件下,采用小压缩比、轧制6道次的相同轧制工艺轧制成厚板,分析了轧制成钢板的组织、性能。结果表明,电渣重熔工艺可以显著改善钢的内部质量,消除偏析和缩松,细化组织,提高钢板的屈服强度和抗拉强度,断面收缩率分别提高1.7和1.9倍。

| Abstract: | Making Q235B and Q345R as examples, this article analyzed the internal qualities of the continuously casting slabs and the ESR ingots. And then, in the condition of laboratory, they were rolled into heavy plates by low reduction ratio and 6 passes. It researched the microstructure and properties of the heavy plates. The results showed that ESR process improved the internal qualities, eliminated the segregations and porosities, refined the microstructure, and increased the yield strengths, tensile strengths and the percentage reductions of area for 1.7 times and 1.9 times. |
