In order to understand the change rules for microstructure and properties of low alloy structural steel with controlled rolling and controlled cooling process, the Mn-B-Cr-Nb-Ti series of Q690 low alloy high strength structural steel was taken as the object of study, the change rules for structure properties with different processes are analyzed through changing the controlled rolling and controlled cooling process. The test results showed that the tensile strength, yield strength and yield ratio of the test steel were all decreased slowly, the elongation was increased and the impact energy at-20 ℃ was decreased periodically with the increase of finish cooling temperature. The microstructure was changed as the rules of ferrite, granular bainite and lath bainite as well as the effects on the properties of the material are different with the decrease of finish cooling temperature.

为了解低合金结构钢控轧控冷工艺下的组织及性能变化规律,以一种Mn-B-Cr-Nb-Ti系Q690低合金高强度结构钢为研究对象,通过改变控轧控冷工艺,分析不同工艺下组织性能的变化规律。试验结果表明:随着终冷温度的升高,实验钢的抗拉强度、屈服强度和屈强比均缓慢下降,伸长率上升,-20 ℃冲击阶段性下降。显微组织随终冷温度降低按铁素体、粒状贝氏体、板条贝氏体的规律变化,对材料性能产生了不同的影响。

为了解低合金结构钢控轧控冷工艺下的组织及性能变化规律,以一种Mn-B-Cr-Nb-Ti系Q690低合金高强度结构钢为研究对象,通过改变控轧控冷工艺,分析不同工艺下组织性能的变化规律。试验结果表明:随着终冷温度的升高,实验钢的抗拉强度、屈服强度和屈强比均缓慢下降,伸长率上升,-20 ℃冲击阶段性下降。显微组织随终冷温度降低按铁素体、粒状贝氏体、板条贝氏体的规律变化,对材料性能产生了不同的影响。

In order to understand the change rules for microstructure and properties of low alloy structural steel with controlled rolling and controlled cooling process, the Mn-B-Cr-Nb-Ti series of Q690 low alloy high strength structural steel was taken as the object of study, the change rules for structure properties with different processes are analyzed through changing the controlled rolling and controlled cooling process. The test results showed that the tensile strength, yield strength and yield ratio of the test steel were all decreased slowly, the elongation was increased and the impact energy at-20 ℃ was decreased periodically with the increase of finish cooling temperature. The microstructure was changed as the rules of ferrite, granular bainite and lath bainite as well as the effects on the properties of the material are different with the decrease of finish cooling temperature.
