This paper was studied on the horizontal continuous casting of Al-xSi(x=10~15%) aluminum alloy. The experiments of the horizontal continuous casting was carried out by the horizontal continuous casting machine for various casting conditions and investigated on fracture types and mechanisms. Surface defect types for the horizontal continuous casting is also investigated. And the study was carried out that the horizontal continuous casting conditions such as casting temperature, cooling rate, and drawing speed affect the hardness and primary silicon size of Al-xSi(x=10~15%) aluminum rod bar. Casting temperature within this experiment conditions don't affect on the hardness of rod bar but the higher casting temperature is the smaller primary silicon size. The higher cooling rate and drawing speed have the higher hardness and the smaller primary silicon size.

The continuous casting is primarily a heat-extraction process in which the heat transfer at various cooling zones profoundly influences quality of products. So development of numerical model is necessarily needed for more specific and clear investigations upon heat transfer mechanism at mold and secondary cooling zones. In this study, heat transfer coefficients which show the characteristic of heat transfer mechanism in mold are calculated for more exact analysis with temperature measured in bloom mold using optimal algorithm, and finally the validity of cooling conditions at secondary cooling zone actually used at field fur 30 Ton bloom type continuous casting of 0.187%C is investigated. From the results of solidification analysis, the characteristic of bloom mold shows a similar tendency with that of previous studies, and optimized cooling conditions for 0.187%C are presented.

Continuous casting machine has been experienced a rapid development to increase productivity with high casting speed and to meet consumer's strict demands for high quality. However, because most of defects and cracks are initially formed in mold and grown into surface cracks during the post process, more specific and clear investigations upon heat transfer mechanism between mold and solidified shell are necessarily needed. In this study heat transfer coefficients which shows the characteristic of heat transfer mechanism are calculated with temperatures measured in bloom mold using optimal algorithm, and thermal analysis are investigated using the calculated heat transfer coefficients. Finally uniformity of solidified shell is investigated for high carbon steel, 0.187%C from thermal analysis.
