Research on Structured Description Framework of High Temperature Molten Metal Accident

Abstract

The high-temperature molten metal leakage accident and its secondary accidents have become urgent problems to be solved in the current metallurgical industry because of their destructive power. The description of the high temperature molten metal leakage accident structure is the basis for studying its evolution law. Based on the idea of collection, this article uses multiple case analysis methods to abstract the accident attributes, and constructs an accident institutionalized description framework with the content of accident types, internal attributes, environmental attributes, management attributes, and hazard assessment attributes. A structured description of the leak. Finally, the “4.18” ladle capping accident of Qinghe special steel in Tieling, Liaoning Province was selected for example verification, and the attribute relationship between the primary accident and the secondary accident was analyzed. The research results have reference value for studying the evolution law of high temperature molten metal leakage accidents and making emergency decisions.
