摘要
Secondary cooling information is critical when modeling the direct-chill (DC) casting process of magnesium alloys. However, accurate data for the heat flux in the secondary cooling zone are scarce, and most reported research is concerned with the DC casting of aluminum alloys. Cooling experiments that simulated the secondary cooling of magnesium AZ31 were conducted in order to observe the influence of various parameters on the different boiling-water heat-transfer phenomena. The heat flux in each boiling regime was quantified as a function of the cooling-water flow rate, water temperature, and initial sample temperature. Equations developed from the cooling experiments could be combined to build "idealized" boiling curves for a given set of DC casting conditions.
