AI Article Synopsis
- The study focuses on how mold flux entrapment affects the quality of IF steel casting, identified as a significant defect in the process.
- Using a high-temperature mold simulator, it was determined that lower melting and viscosity mold fluxes lead to lower temperature and heat flux in the copper mold.
- Results showed that mold flux A (higher melting/viscosity) produced sharper oscillation marks and less slag entrapment compared to mold flux B (lower melting/viscosity), which had deeper marks resulting in greater slag entrapment.
Article Abstract
The slag entrapment defect has become a big issue for the IF steel casting process. In this study, the mechanism of mold flux entrapment in deep oscillation mark of an IF steel shell was studied by a high-temperature mold simulator. Results show that both temperature and heat flux in a copper mold become lower when mold flux B with lower melting and viscosity is used, compared with these when mold flux A with higher melting and viscosity is used. The average thickness of the slag film for mold fluxes A and B is 1.31 mm and 1.63 mm, and the consumption of them is 0.33 kg/m and 0.35 kg/m, respectively. The shell for mold flux A exhibits sharper oscillation marks, while the shell for mold flux B has shallower oscillation marks. These deeper oscillation marks capture the mold flux by overflow of molten steel at the meniscus, which finally produces the slag entrapment defect in the shell.
