摘要利用热机械模拟试验机对Q960E钢不同焊接线能量的热影响区进行模拟,对显微组织及力学性能进行测试分析。结果表明:Q960E钢的显微组织为回火索氏体。随着焊接线能量从1.0 kJ/mm增加到3.0 kJ/mm,热影响区的组织由粗大板条马氏体逐渐向贝氏体和马氏体混合组织转变,无残余奥氏体组织。不预热的试样热模拟后低温冲击功在一定范围内波动,最大冲击功为33 J,最小冲击功为23 J。而预热温度100 ℃的试样热模拟后低温冲击功在线能量2.5 kJ/mm时最低4 J。随着线能量增加,抗拉强度由1 325.9 MPa降低到1 043.3 MPa。根据显微组织以及力学性能分析,Q960E低合金高强度钢在预热温度100 ℃,焊接线能量2.0 kJ/mm时综合性能最优。(1.燕山大学材料科学与工程学院,范艳军,王越洋,李硕妍,郑春雷,宋贞强,2.久益环球(天津)装备制造有限公司,杨永强)To simulate heat affected zones of Q960E steel under different welding heat input by adopting thermal mechanical simulation testing machine, microstructure and mechanical properties were tested and analyzed. Results show that microstructure of Q960E steel is tempered sorbite. As welding heat input increased from 1.0 kJ/mm to 3.0 kJ/mm, structure of heat affected zone gradually changed from thick lath martensite structure to mixture of bainite and martensite without residual austenite structure. The impact toughness of unpreheated sample after thermal simulation fluctuates within a range, with maximum impact energy of 33 J and minimum of 23 J. Conversely, preheated sample at 100 ℃ showed minimum low temperature impact energy of only 4 J at heat input of 2.5 kJ/mm. With increasing heat input, tensile strength reduced from 1 325.9 MPa to 1 043.3 MPa. Based on analysis of microstructure and mechanical properties, Q960E low alloy high strength steel achieves optimum comprehensive performance when preheated 100 ℃ and using welding heat input 2.0 kJ/mm. |

摘要SAE1215H盘条生产过程中表面氧化铁皮出现鼓泡。对SAE1215H盘条采用不同温度加热,保温5 min后空冷,观察SAE1215H试样氧化铁皮形貌并分析氧化铁皮成分,当温度达到950 ℃时,SAE1215H盘条的氧化铁皮表面出现鼓泡,同时有穿透性裂缝,其原因是P元素聚积于氧化铁皮与基体界面,使Fe3(PO4)2含量增高,在950 ℃分解和升华后造成氧化铁皮起泡脱落。研究表明,适当降低轧制过程温度和吐丝温度可以防止SAE1215H盘条表面出现鼓泡。(1.青岛特殊钢铁有限公司,董强 苏永泽,侯建伟 亓奉友 韩莹;2.哈焊所华通焊业股份有限公司,王千瑞)SAE1215H wire rod surface oxide scale occurred bubbling in production process. SAE1215H wire rods were heated at different temperatures and air cooled after holding for 5 minutes, oxide scale morphology of SAE1215H samples was observed and composition of iron scale was analyzed. When temperature reached 950 ℃, SAE1215H wire rod surface oxide scale appeared bubbling and penetrating cracks, which were caused by accumulation of P element at interface between iron sheet and matrix, content of Fe3(PO4)2 was increased, which promotes foaming and detachment of oxide scale after decomposition and sublimation at 950 ℃. Results show that bubbling on SAE1215H wire rod surface can be prevented by reducing rolling temperature and lay temperature properly. |

摘要Ø50 mm HRB500E钢筋因规格大,传统工艺依靠轧后穿水,从边部到心部组织不均匀,实际淬火冷却速率不够,红钢在轧线长时间保持高温状态,钢中先共析铁素体呈网状沿原奥氏体晶界分布,导致屈服平台不明显。通过对高氮钒铁体系、铌钒复合体系、纯钒体系三种不同的成分体系,以及不同的金相组织与轧制工艺下对比试验,找出最合适的成分体系配比和加大预穿水力度增强奥氏体再结晶轧制工艺,解决了屈服平台不明显的问题。(江苏永钢集团有限公司,江苏 张家港 215628)Due to diameter 50 mm HRB500E steel reinforcement large diameter, traditional processes rely on water penetration after rolling, microstructure is uneven from edge to center, actual quenching and cooling rate is not enough, red steel maintains high temperature state for long time on rolling line, and preeutectoid ferrite in steel is distributed in network along original austenite grain boundaries, resulting in unclear yield platform. By comparing three different composition systems of high nitrogen Fevanadium system, niobiumvanadium composite system and pure vanadium system, and different microstructure and rolling process, the most suitable composition system ratio is found out and austenite recrystallization rolling process is enhanced by increasing prewater cutting force, which solves problem of unclear yield platform. |
