低碳微合金化对轧制工艺及钢种性能的影响

Effect of Low Carbon Microalloying on Rolling Process and Steel Grade Properties

鉴于低碳微合金化可显著提高钢材强度、韧性、可焊接性及加工稳定性等,分析探究了低碳微合金化对轧制工艺及钢种性能的影响。为进一步验证各微合金元素对轧制工艺的影响,选取了4个不同钢种(均为低碳钢)进行了热模拟实验;为探究低碳微合金对钢种性能的影响,选取2个钢种采用相同调制工艺,通过观察各金相组织以获取钢种性能。

The low-carbon microalloying can significantly improve the strength, toughness, weldability and processing stability of steel, the influence of low-carbon microalloying on rolling process and steel grade properties was analyzed and explored. In order to further verify the effect of microalloyed elements on rolling process, four different steel grades(all low carbon steel)were selected for thermal simulation experiments. In order to explore the influence of low-carbon microalloying on the properties of steel grades, two steel grades were selected by the same modulation process, and the properties of steel grades were obtained by observing each metallographic structure.
