Method for controlling shape of ingot head

Systems and associated methods for controlling the shape of an ingot head during formation are provided. At the casting end, a chilled bar or other cooling structure may be lowered into an ingot mold and define a reduced casting footprint for forming the ingot head prior to forming the ingot head. Supplemental molten metal may be fed into the reduced casting footprint, and the chill bar may be moved laterally toward the center of the ingot, further reducing the casting footprint. As additional molten metal fills the reduced mold footprint, the ingot may be lowered relative to the quench bar to further increase the height of the ingot head. Additional molten metal may be added until a desired shape of the ingot head is formed. 提供了用于在形成期间控制锭头部的形状的系统和相关联的方法。在铸件端部处，在形成所述锭头部之前，可将激冷棒或其他冷却结构降低到锭模具中并且限定用于形成所述锭头部的减小的铸造覆盖区。可将补充熔融金属进给到所述减小的铸造覆盖区中，并且可将所述激冷棒横向地朝向锭的中心移动，从而进一步减小所述铸造覆盖区。随着额外的熔融金属填充所述减小的模具覆盖区，可相对于所述激冷棒降低所述锭以进一步增加所述锭头部的高度。可添加额外的熔融金属，直到形成所述锭头部的期望的形状为止。
