七十年代以来,人们十分注重提高轧制板带的质量,发展了各种形式的板形控制装置。其中,应用最多并较为成熟的是液压弯辊装置,它是一种简单、有效、基本的板形控制手段。我国除少数几套引进的轧机装备有此装置外,国内尚属研究试用阶段。本文介绍钢铁研究总院四辊冷轧机的液压弯辊装置概况及应用实验结果。 1.实验用轧机和液压弯辊装置轧机是一套三机架冷连轧机,轧机辊缝调整方式是电液伺服液压压上式,在第三机架上装有液压
Since the seventies, people pay great attention to improving the quality of rolled strip, the development of various forms of shape control device. Among them, the most widely used and more mature is the hydraulic bending device, which is a simple, effective, basic shape control. Except for a few sets of imported rolling mills equipped with this device in our country, there is still a pilot phase of research in China. This paper introduces the general situation and experimental results of the hydraulic bending device of the four-high cold rolling mill of the Iron and Steel Research Institute. 1. Experimental Mill and Hydraulic Bending Device The mill is a three-stand tandem cold rolling mill. The roll gap adjustment method of the mill is electro-hydraulic servo hydraulic pressure type. The third rack is equipped with hydraulic pressure
