Research On Schedule Plan And Control Of Blast Furnace Construction Project For Xinxing Ductile Iron Pipes Co.,Ltd. In Handan

Iron and steel industry is an important basic industry in the national economy,as it is the support to the industrialization.In the past 2016,Hebei Province continues to sit firmly on the throne of the largest steel province.In response to the call of the state,the transformation of small blast furnaces into large-scale blast furnaces is an inevitable trend.The upgrading and reconstruction of large-scale blast furnaces have become the focus of the transformation of major steel enterprises.In the integrated iron and steel works,blast furnace construction project construction management is the most complex and most difficult.In the progress of the construction work,people generally do not pay attention to the construction schedule control.When the construction period is short and the work site is small,the construction work can not be carried out normally and orderly due to the large work pressure and the blind rush-time.As quality and other aspects of the problem may occur easily during this construction period which shall result in increased operating costs,construction progress management is the core of blast furnace construction project for Xinxing ductile iron pipes Co.,Ltd.in Handan.Based on the review of the basic theory and literature of the project schedule and control at home and abroad and the analysis of the characteristics and difficulties in the blast furnace construction project for Xinxing ductile iron pipes Co.,Ltd.in Handan,in this paperbreakdown the work structure and allocate the duties according to the actual situation of the project,estimate task sequence and time,find out the key path to develop a scientific and rational project schedule,and optimize the progress of the project through the network plan to implement the initial optimization.At the same time,by estimating the time of each process through probability-based estimation in the key chain,a baseline plan of the project plan is formed,which lays the foundation for the control of project progress.The project schedule control is based on this baseline plan.Based on the customized control flow of the blast furnace construction project for Xinxing ductile iron pipes Co.,Ltd.in Handan,combined with the guarantee of organization,technology,resources and management measures,the project implement dynamic tracking and deviation analysis and variation adjustment,so that the project schedule shall meet the requirements of the construction period.Finally,this paper summarizes the actual situation and the direction of improvement of the relevant theories in the process of formulating the project schedule and control,sets a template for the blast furnace construction project in the future,and provides reference for the project schedule control and management.
