This heat treatment can prevent the formation of large Sr-Ca-Cu-O particles which can form in tape during isothermic heat treatment of high temperature and can release 30〓 phase in the tape.

发现在银套Bi-Pb-Sr-Ca-Cu-O预烧粉末轧制带热处理中37〓相晶粒以（001）晶面平行带面生成；等温高温处理产生含粗大Sr-Ca-Cu-O相颗粒的组织；升温处理可以避免形成Sr-Ca-Cu-O粗粒并消除30〓相。

Aiming at the special deformation mechanism during the with tension rolling of H beam in universal pass, a three-dimensional continuous kinematically admissible velocity field is put forward for the first time, in which, the non-uniform distribution of longitudinal velocity in lateral direction and the special deformation mechanism of the web and flange joint deformation zone are taken into consideration.

针对H型钢在万能孔型中带张力轧制时特殊的变形机理，首次提出了考虑金属横向流动的三维、连续运动学许可速度场；速度场中考虑了纵向流动速度沿横向的不均匀分布以及腹板和翼缘交界变形区的特殊变形状态。

Such as feeding, two-procedure preheating, sealing, oil-filling, washing, two-procedure under heating, knurling, curling, rolling watering line, unloading bowl and photoelectric checking, troubles warning, counting, etc.

如摄食，双预热程序，密封性，加油，清洗，两个程序下加热，滚花，卷曲，轧制线浇水，卸碗以及光电检测，故障预警，计数等，除了这些，它提高了速度和质量在原有的基础，是理想的设备。

In order to improve product strength and malleableness which are suitable for subsequent(cold-rolling) process,based on condition of the workshop,rational range of cooling rates was established.

带钢热轧以后的冷却速度对于钢带的组织与性能有着极其重要的影响，钢种、板厚、终轧及卷取温度和轧制规程等都相同，只是冷却速度不同就能引起性能上的较大差别[1]。

Later reissues bear a Medallic Art Company name. Davison's usually spelled out their last name in full.

达文森父子负责发行的部分通常在边缘轧制了他们姓名中最后一个词的全拼。

The investigation in surface lineal defect of rod are carried on by means of metallograph,grinding test as well as deformation test during roughing roll.

通过对试样进行金相分析，对铸坯表面修磨试验结果分析及对连铸坯在高线粗轧第1道和第2道轧制的受力和变形的分析，发现盘条表面的一种特殊的线状缺陷形成的原因是连铸坯存在边内裂和皮下气泡，粗轧机组(特别是第1和第2架)孔型设计不合理，也促进这种线状缺陷的形成。

Rolling mill is the most important equipment on the rolling line, and the main transmission system is the nucleal components of the rolling mill.

轧机是轧制线上的重要单体设备，而轧机主传动系统又是轧机的核心组成部分。

Piercing mill is the most important equipment on the rolling pipe line,and the frame is the nucleal component of the piercing mill.

穿孔机是轧制钢管的重要设备，而机架又是穿孔机的核心组成部分。

Based on the failure analysis of hot roll, this paper optimizedly adjusts alloy system and summarizes the experience of rolling wiresand improves ail processing properties. Then, it analyses the effects on some natural parameters such as alloy transfer coefficient, surfacing layers, welding current and arc voltage etc.. It confirms the fitting ageing technique. Also, it discusses the microscopic structural transformation back and forth ageing and the effects on hardness change of overlaying metal by some alloying elements including C, Cr, V, W, Mo, Ni, Mn, B, Re through OM, SEM and X-ray diffraction analyses. Finally the abrasive resistance, red hardness, thermal fatigue property and anti-high temperature oxidability are investigated in experimentation.

全文在热轧辊失效分析的基础上优化调整合金体系，总结了焊丝轧制的经验，改善各种工艺性能，分析了几个特性参数的影响，确定了适宜的时效工艺，并通过光学显微镜、扫描电镜和X-射线衍射对时效前后的显微组织转变以及部分合金元素如C、Cr、V、W、Mo、Ni、Mn、B、Re对堆焊层硬度变化的影响进行分析，最后通过试验考察了堆焊层金属的耐磨粒磨损性能、红硬性、耐热疲劳性和抗高温氧化性。

However, semi-steel is made of 10 ~ 20% cementite and pearlitic matrix, there exists no pellet-shaped graphite, so sticking is easy to happen to it, which is not expected dunng rolling.

然而半钢材质是由10-20％渗碳体及珠光体基体所组成，其内不存在球状石墨，所以半钢材质容易产生粘钢现象，这是轧制过程所不希望的。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
