The model considers not only the slab bounce on gauge and hardness , obverse and inverse bounce on width , and the rolling length constraint of the slabs with same width , but also the reasonable arranging of warm - up materials and staple materials 该模型不仅考虑了轧制计划中板坯在厚度和硬度上的跳跃、板坯宽度的正反跳以及相同宽度板坯连续轧制的长度约束，而且考虑了轧制计划中烫辊材和主体材的合理安排。
The work principle and identity of the press with cone - shaped roll have been introduced with expounding use of plc to control the production of such machine of which the technology and control have been based as design of the hardware and software of control system 摘要介绍了轴向轧制的双锥辊辗压机的工作原理和特性，阐述应用可编程控制器控制双锥辊轴向轧机的生产，并且针对其工艺和控制要求，从硬件和软件进行了控制系统的设计。
The configuration of conventional backup and work rolls for revamped 1700 tandem cold rolling mill at wisco was proved unreasonable by systematical test as the cause of work roll edges contact during thin strip rolling and unsatisfactory flatness of product 摘要通过现场跟踪测试和生产实践发现武钢1700冷连轧机组“酸轧联机”改造工程中存在常规凸度辊形配置方案不合理，由此引起了薄规格轧制的工作辊“压肩”现象和轧制过程欠稳定导致成品板形质量欠佳等问题。
For more years , the welded members of steel structure are more popular than the rolled ones in china , but as is well known , the mechanical performance of welded members are effected by many factors : such as the material property of plates , the heat effect during welding process , the residual stress , the weld techniques and so on 一直以来我国使用的钢结构构件以焊接为主，轧制的较少。众所周知，焊接构件的力学性能将受诸多因素的影响，如焊接板材的材性是否一样、焊接产生的热影响以及焊接残余应力和焊接工艺等。
