The DC casting process is characterized by discontinuous cycles of casting followed by a stop and set-up time. A waiting time is required, after each drop, to complete metal solidification in the ingot head and cool the ingot to an adequate temperature prior to removal using a head crane. The sheet ingot cooling time after casting is an important element affecting the total cycle time. The objective of this work is to reduce the cooling time of the ingot in the casting pit to increase productivity. Two approaches were evaluated. The first one is to increase the cooling rate in the pit, and the second, is to strip the pit faster with ingots at a higher temperature. For each method, a complete characterization of the ingot temperature was performed. Constraints and issues were identified, and some possible solutions were explored to eliminate major bottlenecks.
