| Abstract Scope |
Using a self-developed RH snorkel slag adhesion simulation device, simulation experiments were conducted on the slag adhesion behavior of high-carbon steel RH refining slag from a steel plant. The effects of refining slag composition and properties on snorkel slag adhesion were investigated through a combination of high-temperature thermophysical property measurements and thermodynamic calculations performed with Fact sage 8.1. Measures to mitigate slag adhesion were also explored. The composition and properties of the refining slag were optimized by appropriately increasing the basicity and slag index, reducing the melting temperature and viscosity, and minimizing the precipitation of high-melting-point compounds. Industrial application demonstrated that the optimized RH refining slag developed in this study effectively reduced slag adhesion on the snorkel during the RH refining process, resulting in a 25% increase in the service life of the snorkel. |
