| 摘 要： | 介绍了HSLC钢的力学性能、成分和纯洁度控制,讨论了HSLC钢的强化机理.结果表明,在σ8≤450MPa条件下,珠钢电炉-CSP工艺生产的HSLC钢的力学性能与国外同类钢相当.提出了HSLC钢的成分控制要点,开发了电炉终点碳控制和低氧控制技术,发现了低碳钢中存在纳米硫化物、氧化纳、氮化物和碳化物.与HSLA钢类似,HSLC钢亦具有沉淀强化机制,纳米铁碳化物应是主要沉淀强化相.

| Abstract: | The mechanical properties, chemical composition control and cleanness control of HSLC steel were introducted and the strengthening mechanism was discussed. It is pointed out that the mechanical properties level of HSLC steel produced by EAF-CSP technology in Zhujiang Iron Steel Co, Ltd is located at the same position with that of microalloyed HSLA steel produced in foreign CSP plants. The main points of chemical composition and cleanness control were listed and the terminal point control as well as low nitrogen control technology of EAF was developed. It was found that there existed nano-scale sulfides, oxides, nitrides and carbides in HSLC steel. Similar to HSLA steel, the precipation strengthening mechanism is available to HSLC steel. The nano-scale iron carbide would be the main strengthening phase. |
