轧机扩径增速改造设计与实践

济钢二小型围绕成品轧机提速,采取改进轧机径向、轴向调整结构,改进关键部件材质,优化粗、中、精轧节奏匹配等措施,在主机列不做任何改变的情况下,将成品线速度由８．５ｍ／ｓ提高到１０．５ｍ／ｓ,通过轧机扩径的途径,达到了提高横列式轧机产品产量和质量的目的。

Design and Practice of Expanding Diameter and Increasing Speed Reformation of Rolling Mill

Round increasing speed of product mill in No. 2 small section rolling plant of Jinan iron and steel group,some measures included of improving radial and axial regulation mechanism of rolling mill,improving the material quality of key part,optimizing the match of rough rolling, meduim rolling and finish rolling , etc, are taken on. In the condition of unchanging main mill train , the line speed of finished proauct will be enhanced from 8. 5m/s to 10. 5m/s. Through the way of expanding diameter of rolling mill the aim of increasing product putout and quality of transverse rolling will is achieved.
