| Abstract: | In this work, by means of a series of C. C. hot modelling experiment we got the shells in initial 3 seconds of solidification. And then, using a special software to analyze these experimental results,which is based on an one-dimension analytics of heat-transfer in solidification process, we got the distribution of heat-flow and heat-transfer coefficient between the surface of mould and initial solidification shell for different mould materials. According to these experimental results, the effect of Hot-Top mould matsrial on the heat-transfer in initial solidification process was investigated. |
