2007年8月1日 · Mathematical analysis of continuous variable crown (CVC) roll contour used in CSP production line was conducted and the roll contour function of CVC roll was obtained.

In 1980 already, the basic principle of CVC ® (Continuously Variable Crown) was invented to perfectly supplement the established work roll bending system. It allowed work rolls with a special contour to be axially shifted and the resulting roll crown and hence the roll gap profile to be continuously influenced.

CVC technology is one of the widely used roll shifting technologies. Many research works have been conducted on roll contour curve design, shifting strategy optimization, and new kinds of work roll with shifting function. Xu et al. 13 introduced a method to design the CVC-Plus work roll curve.

CVC(Continuously Variable Crown)轧辊,就是连续可变凸度轧辊,其辊身曲线呈S型,图1给出了CVC轧辊的辊系布置及其工作原理。 两个外形相同的轧辊相互倒置180°布置,通过两辊沿相反方向的对称移动,可获得从中凹到中凸连续变化的辊缝形状。

CVC technology is generally called continuous variable crown control technology. It was originally applied to the two-roller rolling mill and was successful. In recent years, it has been commonly used on the four-roller rolling mill and six-roller mill, and has achieved remarkable results.

Axial shifting of these rolls results in a continuously variable crown (CVC) system, and the crown gets imparted to the rolled strip. In addition, crown builds up owing to a number of other...

2023年1月6日 · In order to improve the crown control ability and high quality to meet the Profile Contour Flatness Control (PCFC) requirements of wide electrical steel in the hot strip mills (HSMs), the control strategy of multi-stand work roll bending forces and shifting stroke on the crown for the universal variable crown (UVC) mill is established based on ...

摘要: 跟踪某2250 mm热轧生产线CVC辊形实际窜辊数据发现,连续变凸度(CVC)辊形常窜到两端极限位置.分析表明,CVC辊形的二次凸度调控能力随带钢宽度减小而呈二次方下降趋势,表现出对较窄带钢凸度控制能力的明显不足.Smart-Crown辊形也存在同样问题.提出一种新的先进 ...

upc轧机是德国mds研制的万能板形控制轧机，是继hc、cvc技术之后又一种可改善板形的轧辊横移式轧机。其原理是将普通4辊轧机的工作辊磨成雪茄型，大、小头相反布置，构成一个不同凸度的辊缝。
