| 1. | The development of modern coiler system is mainly aiming at improving the yield and quality of product 现代热轧卷取机的发展主要着眼于提高产品的产量和质量。 |
| 2. | We need on long - term : cr , cr full hard , hr and hr p & q in term of coil / sheet / top - end 我们长期需要冷轧和热轧卷板的二级料,其形式诸如:非标的一级剩馀,小卷和切头。 |
| 3. | Hot - rolled coil , for instance , the sheet steel for cars and fridges , rose from around $ 200 a tonne to more than $ 600 例如热轧卷钢(用来制造汽车和冰箱的板材)价格从200美元一吨涨到了600美元一吨。 |
| 4. | Because of the collision between lap of strip steel and unit roller , too big an impact occours during the initial coiling of previous coiler of hot rolling 以往热轧卷取机在卷取开始时,由于带钢头部搭头部位与助卷辊发生冲撞,产生过大的冲击。 |
| 5. | This provides theoretic and experimental base for developing high - level step - by - step control system and improving installation of coiler and quality of production 为研制高水平的热轧卷取机步进控制系统,提高卷取机装机水平和卷取质量提供了理论基础与实验依据。 |
| 6. | Experiments show that in the system , step - by - step control is realized , the utilization rate of materials is gained . this model lays the basis for developing the better coiler 实验证明,该控制系统能实现带头的自动步进回避,提高材料利用率,为研制高水平热轧卷取机奠定基础。 |
| 7. | Abstract : the structure , composition analysis and mechanical test of q235 hot - rolled strip showed that main season of fracture during forming and welding is high nitrogen , oxygen and inclusion content 文摘: q235钢热轧卷板在冲压和焊接成形时出现开裂,对其进行化学分析、宏观和微观组织观察及力学性能测试,结果表明:氮、氧及夹杂物的含量高是该钢冲压性和可焊性差的主要原因。 |
| 8. | Modern coiler of hot rolling is coiling faster and faster . based on the physical simulation model built in laboratory , a series of experiments have been conducted to study how to evite the step even faster and more placidly 现代热轧卷取机卷取速度越来越快,为探讨如何更快速、更平稳地实现助卷辊的台阶回避,针对实验室建造的热轧卷取机系统半物理模型进行了仿真和实验研究。 |
| 9. | Abstract : this paper presents an analysis of the moment of inertia ofcoiler in hot strip mill in detail , the derivation of theoretical formula of the inertia and the analysis , taking 2050 hot strip mill for example , of the inertia change rule and the compensation of moment of inertia 文摘:对热轧带钢卷取机的惯性力矩进行了分析,推导出惯性力矩的理论表达式,并结合2050热轧卷取机分析了惯性力矩的变化规律,对惯性力矩进行了补偿。 |
| 10. | Hydraulic servo system used in coiler is mainly to realize the step - by - step control . by using the servo system , vibration and striking are largely decreased , the accidents are reduced , and the level of automation is largely improved , as well as the quality of production 电液伺服系统在现代的热轧卷取机中的应用主要是实现带头的自动步进回避,这样就有效地消除冲击,同时也使卷取过程中各种事故大为减少,大大提高了轧制过程的自动化水平,产品产量和质量。 |
