日本金属公司研制的KZR轧机，是在传统的ZR轧机（Sendzimir轧机）的基础上进行改进，即在原来的ZR轧机上安装了新颖高效的“双AS－U系统”和具有“神经／模糊逻辑控制的ASC系统”。其中“双AS－U系统”是通过弯曲支承环轴而达到控制各种板型的装置，其板型控制能力是普通ZR轧机 The KZR mill, developed by Japan Metals Corp., is based on the traditional ZR mill (Sendzimir mill) with the addition of a new highly efficient “dual AS-U system” to the original ZR mill and a “ Controlled ASC system ”. Among them, the “Dual AS-U System” is a device that controls various plate types by bending the support ring axis. The plate type control capability is that of an ordinary ZR rolling mill
