Abstract

Abstract

The steel process contains abundant residual valuable components, which come from a wide range of sources and have a complex composition. It is necessary to utilize these components as resources efficiently. This article is based on the theory of metallurgical processes, analyzes the sources, transformation, and migration laws of residual components in the steel process, reveals the causal relationship between the disorder of residual components and carbon pollution emissions in the steel process, and proposes the theoretical viewpoint of self-consistent recycling of valuable components in the steel process, that is, inputting a certain amount of governance material flow and energy flow (negative entropy flow) to promote the disordered residual components and their carried residual energy to return to the main process of steel, or become raw materials for resource recycling in other industrial processes. At the same time, based on the theoretical viewpoint of self-consistent resource utilization of material energy in the steel process, typical process methods and application cases of self-consistent recycling of valuable components, such as non-metallic organic components, non-metallic inorganic components, and heavy (alkali) metal components are introduced.
