【Abstract】 In order to evaluate the energy efficiency of heating furnace operation, six energy efficiency evaluation models were used to develop energy consumption analysis, including thermal efficiency, product unit consumption, hot charging rate, tapping temperature hit rate and air consumption coefficient. By further defining and analyzing the models, an evaluation system is formed. Through data mining, the change mechanism of the key production index of a heating furnace on energy consumption was studied. Using the research results, an energy efficiency evaluation system was developed to achieve online index calculation and evaluation, improve the level of refined energy management, and reduce energy consumption in the production line by 4.3%.更多还原
