Abstract：In order to achieve the casting speed of 2.5m/min on No.3 slab caster of Shougang Jingtang steel group, the mold cooling density, mold flux composition and structure of submerged entry nozzle were optimized based on the current casting parameters. Results of industry practice showed that, the casting speed could be held at 2.3m/min stably after the parameters optimized. The surface oscillation was improved obviously, the average heat flux of broad and narrow face was stable, the mold copper temperature filed was rational, the thickness of liquid flux was suitable and the powder consumption was increased. The casting speed could be increased from these industry practice results.
