邯钢新区3500mm中厚板轧机机架安装找正最新方案研究优化
Research and Optimization of Latest Approach for Alignment and Installation of 3500mm Medium-Heavy Plate Rolling Mill Frame in Handan New District
本文着重探讨邯郸新区中板厂粗轧机底板和机架的安装过程。为实现双机架轧制,现有的 3500mm单机架被迁移至精轧机位置,同时新建一套 3500mm 轧机以取代粗轧机。本文详细介绍了底板安装过程,强调底板垫铁对轧机精度的影响,以及如何通过垫铁调整来优化精度。此外,还阐述了粗轧机机架的安装过程,包括上下横梁的安装和组合键的安装。最后,通过第三方重新测试牌坊的垂直度、扭曲、水平度和底板标高,以确保工程质量。本研究聚焦于搬迁项目中的关键步骤和精度控制,为确保项目顺利完成提供了宝贵的指导和实践经验。
This paper focuses on the first-phase project of Handan New Zone Medium Plate Plant,which is part of the Handan Iron and Steel relocation project.The study specifically investigates the installation process of the roughing mill's bottom plate and frame.To achieve dual-stand rolling,the existing 3500mm single stand is relocated to the finishing mill position,and a new set of 3500mm rolling mill is produced to replace the roughing mill.The paper provides a detailed account of the bottom plate installation procedure,emphasizing the impact of the bottom plate cushion on mill precision and how to optimize precision through cushion adjustment.Additionally,the installation process of the roughing mill frame is elaborated,including the fitting of upper and lower beams and the installation of combination keys.Finally,a third-party retesting of the verticality,twist,levelness,and base elevation of the portal is carried out to ensure project quality.This study focuses on key steps and precision control in the relocation project,offering valuable guidance and practical experience to ensure the successful completion of the project.
