EVM-2CP型光电位置检测器在二次冷轧机组的应用

Application of EVM-2CP Photoelectric PSD in DCR

随着自动化的高速发展和对产品质量要求的提高,在轧制过程中,需要对带钢在作业线上的位置进行连续检测,对带钢位置进行连续稳定的控制。特别是在高速轧制线,对于带钢位置的精确控制尤其重要,位置对中控制器对于带钢的稳定控制,有效地保证了高速稳定的轧制过程,产品的质量也相应得到了可靠的保证。宝钢分公司冷轧薄板厂二次冷轧机组采用了EMG公司的新型EVM-2CP光电位置检测器,利用光电检测技术对带钢位置进行检测和控制,文章阐述了光电检测技术及其现场应用情况。

With fast development in automation and higher requirement for product quality, it is necessary that the position of steel strip on the production line be constantly detected and controlled steadily. It is particularly important to control position of strips on the high speed rolling line. Center position controller（CPC） can be used to control edge of strip accurately, which will effectively ensure the rolling process steadily at a high speed, and guarantee the quality of products at the same time. DCR（ double cold reduction） unit of the Steel Sheet Cold Rolling Plant, Bao- steel Branch, has adopted the EVM-2CP PSD, a photoelectric position detector, manufactured by EMG Company to detect strip＇ s position. This technology and its applications on the worksite are introduced in this article.
