Theoretical Energy Consumption

Thermodynamic analysis method for iron and steel manufacturing system is developed to describe the energy flow. The theoretical energy consumption for the manufacturing process is proposed to analyze the energy-saving potential. Energy balance based on enthalpy with a uniform reference state is established to analyze the amounts and forms of energy flow in the manufacturing system. The energy-saving potential of blast furnace system is discussed to choose the appropriate energy-saving methods and technologies.

Energy saving of iron-making system and secondary energy recovery are the main approaches for the Chinese steel industry’s sustainable development. The theoretical analysis of secondary energy generation of four typical BF-BOF steel manufacturing processes showed that improving the resource and energy efficiency, and strengthening recovery and rational utilization of by-product gases are the main way of energy saving for steel industry. According to the status of secondary energy recovery of Chinese steel industry, the technological development tendency energy saving, greenhouse gas emission reduction for Chinese steel industry are presented.

Iron And Steel

The iron and steel industry annually consumes about 10% of electricity in China, while the utilization efficiency is relatively low. A two-step energy-saving method for steel enterprise is proposed in this paper. The production plan is regulated to minimize the energy utilized in steel rolling. The electrical load is forecasted according to the optimized steel-rolling plan and the reactive power is compensated to minimize the active power loss and voltage fluctuation. Practical application in Jigang Group Co., Ltd shows the efficiency of the proposed method.
