In this paper, the effects of adding rare earth into A572.Gr65 steel on its inclusions, microstructure and properties were studied with industrial experiments. The results showed that the inclusions in steel were mainly Al2O3 and Al2O3-CaO before add the rare earth and the size was about 5 μm as well as the inclusions were changed to spherical RE2O2S with the size less than 2 μm after add the rare earth. The thermodynamic and dynamics calculations showed that RE2O2S was the most easily formed inclusion in steel after add rare earth as well as the diffusion rate of RE3+ and Al3+ in the intermediate layer of RE2O2S·Al2O3 was the restrictive link of modified rare earth inclusions. After add the rare earth, the microstructure of hot rolled plate was refined as well as the impact and tensile properties were increased with the increase of rare earth content.

文章通过工业实验研究了向A572.Gr65钢中加入稀土后对其夹杂物、组织和性能的影响。结果表明,加入稀土之前,钢中夹杂物主要是Al2O3和Al2O3-CaO,尺寸约为5 μm左右,加入稀土之后,夹杂物变成不足2 μm的球状RE2O2S夹杂物。并且通过热力学、动力学计算表明,添加稀土之后,钢中最容易生成的夹杂物是RE2O2S,而RE3+和Al3+在RE2O2S·Al2O3中间层中的扩散速率为稀土变质夹杂物的限制性环节。加入稀土后,热轧板微观组织有所细化;冲击和拉伸性能随稀土含量的增加而提高。

文章通过工业实验研究了向A572.Gr65钢中加入稀土后对其夹杂物、组织和性能的影响。结果表明,加入稀土之前,钢中夹杂物主要是Al2O3和Al2O3-CaO,尺寸约为5 μm左右,加入稀土之后,夹杂物变成不足2 μm的球状RE2O2S夹杂物。并且通过热力学、动力学计算表明,添加稀土之后,钢中最容易生成的夹杂物是RE2O2S,而RE3+和Al3+在RE2O2S·Al2O3中间层中的扩散速率为稀土变质夹杂物的限制性环节。加入稀土后,热轧板微观组织有所细化;冲击和拉伸性能随稀土含量的增加而提高。

In this paper, the effects of adding rare earth into A572.Gr65 steel on its inclusions, microstructure and properties were studied with industrial experiments. The results showed that the inclusions in steel were mainly Al2O3 and Al2O3-CaO before add the rare earth and the size was about 5 μm as well as the inclusions were changed to spherical RE2O2S with the size less than 2 μm after add the rare earth. The thermodynamic and dynamics calculations showed that RE2O2S was the most easily formed inclusion in steel after add rare earth as well as the diffusion rate of RE3+ and Al3+ in the intermediate layer of RE2O2S·Al2O3 was the restrictive link of modified rare earth inclusions. After add the rare earth, the microstructure of hot rolled plate was refined as well as the impact and tensile properties were increased with the increase of rare earth content.
