| 1 | 双辊薄带铸轧熔池流热耦合的三维数值仿真显示文摘把双辊铸轧熔池处理成钢水和大气的自由表面两相流,考虑了实际生产过程中铸轧辊的转动,建立了铸轧熔池内钢水三维流动传热耦合数学模型。通过此模型,计算并分析了采用楔形布流器时,铸轧熔池内钢水的流动形式和温度分布情况。结果表明,钢水在熔池内以布流器侧水口的位置为基准,在侧水口上部和下部区域分别存在着强弱程度不同的钢水回旋区域。Kiss点(凝固结束点)的高度在纵向上根据侧水口的位置近似呈余弦形式分布。 | 侯晓东 朱光明 刘志良 | 2010 | 特种铸造及有色合金2010，30，11： | 8 |
| 2 | 双辊薄带连铸过程数值模拟显示文摘针对双辊薄带连铸过程,使用了耦合湍流流动和凝固传热的三维数学模型,模拟计算了使用楔型布流系统浇注时,连铸熔池内钢水的流动形态和凝固情况。结果表明,楔型布流系统可使钢水在熔池内合理分布,有利于均匀凝固。 | 王波 张捷宇 樊俊飞 方园 安胜利 | 2007 | 特种铸造及有色合金2007，27，3： | 7 |
| 3 | 基于有限元法的双辊铸轧熔池内钢液流动规律的研究显示文摘把双辊铸轧熔池看做钢液和大气的两相自由表面流,采用有限元法对钢液的流动规律进行研究,并对比分析自由液面以及铸辊的转动对熔池流场的影响。结果表明,把熔池液面处理成平面时,液面附近钢液的流速计算不真实,计算结果会使得液面处的速度在铸带宽度方向上分布极不均匀,不能用此模型研究熔池的液面波动情况;忽略铸辊的转速有可能导致熔池下部流场形式的变化,会使得下部回旋减弱甚至消失,误差较大。 | 侯晓东 朱光明 | 2010 | 铸造技术2010，31，5： | 5 |
| 4 | 双辊薄带连铸铸辊材质及水冷结构分析显示文摘比较了不同成分铜合金的高温表面强度、抗拉强度,模拟冷却孔数量对热传导和温度场的影响规律。选用铬锆铜合金制成了双辊薄带连铸铸辊,在相同的工艺条件下分别采用合金钢铸辊和铬锆铜合金铸辊进行了高速钢双辊薄带连铸实验。结果表明:铬锆铜质铸辊的冷却能力较合金钢质铸辊提高60%,铜辊铸带中心层质量提高,裂纹减少;铜辊铸带的奥氏体晶粒度较钢辊铸带提高一级,凝固过程中析出的共晶碳化物也以颗粒状和鸡爪状为主,没有发现钢辊铸带中存在的半网状共晶碳化物。 | 张彩东 章仲禹 梁小平 丁培道 | 2009 | 重庆大学学报(自然科学版)2009，32，6： | 4 |
| 5 | 双辊薄带连铸熔池内钢液流动的混合行为显示文摘采用数值模拟的方法研究了双辊薄带连铸熔池内钢液的传输行为,分析了采用V形布流系统时熔池内钢液的流动状态和混合特性.计算了熔池自由表面处的湍流动能大小和流体停留时间分布.结果表明,钢液在熔池内均匀分布,有利于薄带坯的均匀凝固.侧封板处钢液更新速度加快,液面波动加强,有利于防止液面结壳. | 张捷宇 王波 周国治 樊俊飞 任三兵 赵顺利 | 2008 | 上海大学学报(自然科学版)2008，14，5： | 3 |
| 6 | Thermal contact conductance at continuous roll-casting interface显示文摘The effects of surface roughness, strain rate, friction coefficient and pressure on real contact area were analyzed based on the research of Stupkiewicz. The real contact area model taking account of the effect of friction and deformation of material was obtained. The model of contact conductance at the rolling interface was obtained by integrating the specific feature of heat transfer through the interface of continuous roll-casting. The results indicate that the real contact area increases obviously when the material is under yield, and the real contact area varies inversely with surface roughness, whereas it varies exponentially with friction coefficient, strain rate and pressure, and the power factor depends on strain rate. | 胡仕成 马维策 杜磊 李晓谦 钟掘 | 2007 | Journal of Central South University of Technology2007，14，3： | 1 |
| 7 | Effects of the microstructure of twin roll cast and hot rolled plates on the surface quality of presensitized plates显示文摘The effect of the microstructure of plates fabricated both in the traditional process, involving casting, hot rolling and cold rolling(HR), and in the novel twin roll casting + cold rolling(TRC) process on the surface quality of presensitized(PS) plates was analyzed by optical microscopy(OM), scanning electron microscopy(SEM), and energy-dispersive X-ray spectroscopy(EDXS). The formation of pores on the surface of the electrolyzed HR plate could be attributed to the presence of approximately 1-μm-sized large Al–Fe precipitates in the HR plate compared to the smaller precipitates in the TRC plate. Moreover, residual graphite lubricants used during the TRC process were entrapped on the surface of the TRC plate during the subsequent rolling process. The entrapped pollutants tended to further deteriorate the formation of pores on the surface of the TRC plate, and no residual carbon was detected on the surface of the HR plate. Furthermore, the surface quality of the TRC plate can be improved by surface cleaning before the cold rolling process, which could dramatically lower the residual graphite on the surface. | Yuan-Zhi Zhu Ya-Feng Zhang Chao-Qi Zhao Feng Zhou | 2014 | International Journal of Minerals,Metallurgy and Materials2014，21，9： | 0 |
