The invention discloses a method and system for optimal modeling of energy consumption of energy flow of a galvanizing unit. An energy model is mainly established for important energy consumption of acontinuous hot-galvanizing production line; an energy flow theory is utilized, energy consumption composition of electric energy and heat energy conversion in two parts of a heating furnace and a zinc pot in the production line of the galvanizing unit is analyzed on the basis of energy conservation, composition and characteristics of the energy flow are especially explored, energy input and output balance equations are respectively established according to internal relations and mapping mechanisms of output power and various process parameters, and the problem about the external input energyof the entire is minimal galvanizing production line is solved. The energy model is obvious, reasonable, simple and accurate in meaning, the problem about energy consumption calculation of the galvanizing unit is solved, the foundation is provided for further study on process parameter optimization of energy efficiency and completion of the research on multiple-objective sequencing optimization, and processing energy consumption can be evaluated and predicted as well.

Description

technical field [0001] The invention belongs to the field of energy consumption optimization of a galvanizing unit, and relates to a method and system for optimizing modeling of energy flow and energy consumption of a galvanizing unit. Background technique [0002] my country's GDP accounts for about 8.6% of the world's total, but its energy consumption accounts for 19.3% of the world's total; energy consumption per unit of GDP is 3.3 times that of the United States, 7 times that of Japan, and 2.5 times that of the global average. The iron and steel industry is a major energy consumer. The energy consumption of China's iron and steel industry accounts for 16.1% of the country's total energy consumption, while the total industrial output value only accounts for 3.2% of the total GDP output value. Under the new normal of China's economy, the steel industry is facing increasingly severe challenges. China's steel industry, which accounts for about half of the world's steel produ...
