The Use of Hot Stage Microscope to Analysis the Fluidity of High Speed Mold Powders in Continuous Casting of Steel

The purpose of this research is evaluation of the effects of chemical compositions on the fluidity of steel continuous casting high speed mold powders in laboratory. Thermal microscope analysis was used to compare the fluidity of generated powders with that of the industrial mold powder. A sample purpose with low fluorine and other samples purposed from mixture of iron oxide، zinc oxide، sodium carbonate and titanium oxide showed similar fluidity to the industrial mold powder. These powders can be substituted for high speed casting powder in steel continuous casting processes.
