Green Manufacturing Process of Shougang Jingtang Steel Plant

摘要

Shougang Jingtang Steel Plant is the project which is built based on the concept of new generation recycling iron and steel process, with characteristics of "three functions", namely iron and steel product manufacture, high efficient conversion of energy, and disposal of wastes by reutilization. In engineering design, on the strength of theory of metallurgical process engineering, the advanced iron and steel manufacturing process of static process structure has been established by construction of two blast furnaces, one steel making plant and two hot rolling production lines, the advanced interface technology on ironmaking and steelmaking process has been developed, and the complete process of energy flow networking framing technology has been created. Energy consumption is reduced, with sufficient recovery of gas, heat and surplus energy during iron and steel manufacturing process, as well as emission reduction of dust and pollutant so as to achieve green iron and steel manufacturing and recycling economy, and energy utilization efficiency has an outstanding improvement. This paper introduces the green iron and steel manufacturing process of Shougang Jingtang Iron & Steel Plant, and establishment of its energy flow network.
