Continuous casting sealing method

A casting furnace for manufacturing a metal casting comprises an interior chamber and a secondary chamber through which the metal casting passes from the interior chamber into external atmosphere. A seal along the secondary chamber surrounds and seals against the metal casting to separate the interior chamber from the external atmosphere in a manner which allows for an extended period of continuous casting. A force producing mechanism typically forces the seal against the metal casting. Multiple seals may be used sequentially to increase the duration of the sealing capability and the continuous casting process.

Homogenization and heat-treatment of cast metals

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.
