基于符号经济模型的转炉--精炼工序热经济分析
Thermoeconomic analysis on the converter-refining procedure based on the symbol ex-ergy-economic model
摘要
Abstract
Taking the converter-refining procedure of a steel plant as an example, symbol exergy-economic model was established by the exergy-economic analysis method. Then the cost balance equation was constructed, and supplementary equations were estab-lished. The unit exergy price and thermal-economic cost of each exergy flow in the procedure were obtained on the converter-refining procedure through thermal-economic analysis. The results show that the thermoeconomic cost of per ton molten steel in the converter-ladle refine process is the lowest, which is 2243. 12 RMB. The thermoeconomic cost of per ton molten steel in the converter-CAS refi-ning process comes second, which is 2259. 92 RMB. And the converter-RH refining process has the highest thermal-economic cost of per ton molten steel, which is 2270. 16 RMB. From the standpoint of energy conservation and cost reduction, the converter-refining process is the reasonable process for SPHC steel production.关键词
