BENCHMARKING OF INFLUENTIAL FACTORS AND ENERGY CONSUMPTION IN SHOUGANG THREE PLANTS

摘要

Great progress of energy conservation in SHOUGANG is made in recent years, but there is still some gap compared with international advanced steel enterprises. To lower steel comprehensive energy consumption and dig its energy-saving potential in SHOUGANG further, method of energy consumption theory analysis is applied in steel comprehensive consumption benchmarking from the factors such as technical flow, process energy consumption and steel ratio coefficient in SHOUGANG three new-built plants such as SHOUQIN, QIANGANG and JINGTANG. Analysis result shows that it is the effective approach to lower steel comprehensive consumption by shortening flow, lowering process energy consumption in iron-making and iron-steel ratio. By benchmarking of process energy consumption in SHOUGANG three new-built plants, it shows that iron-making process energy consumption in QIANGANG is lowest, sinter and steel-making process energy consumption in SHOUQIN is lowest and hot rolling process energy consumption in JINGTANG is lowest, but higher than the advanced Chinese steel enterprises, so some basic measures to lower energy consumption are put forward, and the best optimizing effect of steel energy-saving can be reached by combining and optimizing with single equipment and systemic energy-saving technology on the base of single energy-saving technology applied fully and energy efficiency of single equipment exerted further.
