发布时间：2019-05-22 03:27
【摘要】：SGQG热轧酸洗线为SG设计院设计的推拉式浅槽紊流式酸洗线,属于单卷独立酸洗的断续式生产线,适于厚度较厚和强度较高的热轧板的酸洗,生产的产品多数为低端产品,相比连续式酸洗线,在表面质量、板形等方面不具竞争优势。随着钢材市场产能逐渐过剩,市场供过于求的形式逐渐凸显,竞争已达到白热化阶段,为了进一步提升产品效益,SGQG热轧产品计划往高端转型,即更薄、更宽、更精确的产品,以便追求更高的利润空间,这就需要产线设备升级,以便提供必要的硬件支撑,因此提出SGQG热轧酸洗生产线改进项目,增加破鳞拉矫机、热轧测厚仪改造、表面质量检测仪、边降仪等设备。首先本文对项目进度管理的相关理论以及文献进行了陈述,包括项目进度计划概念、编制方法以及项目进度控制概念、内容、方法等等,其次针对SGQG热轧酸洗生产线改进项目的特点,尤其是需要在产线正常运行的情况下进行设备升级及改进,对项目进度控制提出了更高的要求。通过分析SGQG热轧酸洗生产线改进项目的整体情况,包括项目背景、项目内容、项目目标等等,同时结合项目进度管理的相关理论及知识,利用计划分解图、网络计划图、甘特图、关键点法等知识内容,分析出SGQG热轧酸洗生产线改进项目可能存在的问题及不确定因素,同时分析可能出现问题的各种原因,并提出解决措施及方案,最后制定了适合于本项目的进度计划及进度控制。
[Abstract]:SGQG hot rolling pickling line is a push-pull shallow tank turbulent pickling line designed by SG Design Institute. It belongs to a single coil independent pickling production line, which is suitable for pickling of hot rolled plate with thicker thickness and higher strength. Most of the products are low-end products. Compared with continuous pickling line, it has no competitive advantage in surface quality, shape and so on. With the gradual overcapacity in the steel market, the form of oversupply in the market has gradually become prominent, and the competition has reached the white-hot stage. In order to further improve the efficiency of the products, SGQG hot rolled products plan to transform to the high end, that is, thinner, wider and more accurate products. In order to pursue higher profit space, it is necessary to upgrade the production line equipment in order to provide the necessary hardware support. Therefore, the improvement project of SGQG hot rolling pickling production line, the addition of scale breaking straightening machine, the transformation of hot rolling thickness measuring instrument and the surface quality detector are put forward. Side drop instrument and other equipment. First of all, this paper describes the related theories and literature of project schedule management, including the concept of project schedule plan, compilation method, project schedule control concept, content, method and so on. Secondly, according to the characteristics of the improvement project of SGQG hot rolling pickling production line, especially the need to upgrade and improve the equipment under the condition of normal operation of the production line, the project schedule control is put forward higher requirements. By analyzing the overall situation of SGQG hot rolling pickling production line improvement project, including project background, project content, project objectives and so on, combined with the relevant theory and knowledge of project schedule management, using plan decomposition diagram, network plan diagram, Based on the knowledge contents of Gantt chart and key point method, this paper analyzes the possible problems and uncertain factors in the improvement project of SGQG hot rolling pickling production line, analyzes the various causes of the possible problems, and puts forward some measures and schemes for solving the problems. Finally, the progress plan and progress control suitable for the project are worked out.
