Energy structure and process optimization for the aluminum industry

The metallurgical nature of production flow was compared between aluminum and iron & steel under structural characteristics of current production flow and energy utilization states in the aluminum industry. The production flow was divided into process sections. The energy structure and energy dissipation disciplines of the aluminum industry were synthetically analyzed. Referred to the practice of energy-saving technology in the iron and steel industry, the systematic energy saving potential was pointed out in the aspects of process improvement, energy structure optimization, industrial waste utilization and excess energy recycling, etc. An ordered and high efficiency mode after electrolysis was proposed in the production flow structure.
