    摘要： The invention relates to an apparatus for direct chill casting ingots with in-situ homogenization. Large particles of eutectic material may form in the solid ingot and the metal may exhibit macrosegregation of alloying components, especially when large ingots are cast in this way. This can be alleviated by applying a first liquid coolant to the ingot emerging from the mold, removing the first liquid coolant at a certain distance along the ingot by means of a wiper, and then applying a second liquid coolant to perform a quench at a greater distance along the ingot. The quench raises the level of the molten sump in the ingot, which helps to overcome the indicated problems, without affecting the desired temperature rebound of the ingot shell (usually at least 425°C (797°F)) for a time effective to cause in-situ homogenization.

    摘要： A method of casting a metal ingot with a microstructure that facilitates further working, such as hot and cold rolling. The metal is cast in a direct chill casting mold, or the equivalent, that directs a spray of coolant liquid onto the outer surface of the ingot to achieve rapid cooling. The coolant is removed from the surface at a location where the emerging embryonic ingot is still not completely solid, such that the latent heat of solidification and the sensible heat of the molten core raises the temperature of the adjacent solid shell to a convergence temperature that is above a transition temperature for in-situ homogenization of the metal. A further conventional homogenization step is then not required. The invention also relates to the heat -treatment of such ingots prior to hot working.
