英国戴维·麦基(Davy Mckee)公司将板型自动控制系统(VIDIPLAN)与日本住友金属工业公司(Sumitomo)的变凸度支承辊(VariablCrown Roll简称VC辊)结合在一起,首先用于日本的一台铝材轧机改造上。这对于带材平直度的控制,取得了非常理想的结果。即使在比较恶劣的条件下,仍能以比较高的速度轧出很平直的带材,使液压技术在继自动厚度控制(AGC),液压弯辊之后,进一步应用在板带轧机上。用比较高的油压使有镶套的支承辊变更凸度,用来补偿轧辊的变形,而生产出乎直的带材来。VIDIPLAN+VC系统的工作原理如图1。最近英国已在新设计的轧机上推广这项新技术,预计不久将象液压AGC板型自动控制和液压弯辊一样,广泛应用在轧机上。
Davy McKee, a British company, combined VIDIPLAN with Sumitomo’s VariablCrown Roll (VC Roller) for the first time in Japan The transformation of an aluminum mill. This for the strip flatness control, achieved very good results. Even in harsher conditions, the very flat strip can be rolled at a relatively high speed, allowing hydraulic technology to be further applied to strip rolling mills following automatic thickness control (AGC) and hydraulic bending. With a relatively high hydraulic pressure to change the crown with a set of support rollers, used to compensate for the deformation of the roll, and to produce almost straight strip. VIDIPLAN + VC system works as shown in Figure 1. Recently, the UK has rolled out the new technology on newly designed rolling mills and is expected to soon be used extensively on rolling mills, like the hydraulic AGC form-factor automatic control and hydraulic bending rolls.
