ABSTRACT:The medium plate is important in modern industry , usually accounts for about 10% of the total output of steel.The medium plate is widely used in infrastructure construction, shipbuilding, engineering machinery, container, construction and other industries.These industry put forward higher requirements on the external and internal quality of the medium plate.so,each big steel companies upgrade or expansion the original medium plate production line.In order to ensure the project is technically feasible and economically reasonable, each steel companies has embarked on a scientific, careful analysis of the technical and economic activities. 

    The graduation design is carried out on an steel enterprise’s technical and economic analysis of 2300 plate production line’technological transformation.This article first has carried on the appraisal to the project objectives and product scheme; secondly, evaluate process and plant layout, and evaluated the selection of main equipment; then the make the evaluation of production capacity and financial situation of the whole production unit; analysis the whole project with uncertainty analysis and comprehensive financial evaluation, gives the project financially reasonable conclusion, finally provides a more scientific and rational investment benefit analysis report for the enterprise
