Study on Effect of Technical Parameter on Fluid Flow and Solidification in Steel Strip Roll-Casting Process

Abstract:

Article Preview

A 3-D coupled numerical model for flowing distribution and temperature distribution in twins strip roll-casting process is developed, and the influence of technological parameter on roll-casting process is studied. As a result, lower superheat can get more homogeneity structure in thickness direction, but the metal will solidify in the casting system if the superheat is too low, which doesn’t benefit the slag inclusion floating up. When the velocity is between 6m/mim and 8m/min, the end-point will be at 2~8mm above the anastomotic point. The model can provide the theory to the control on strip roll-casting process.
