ABSTRACT:
The disclosed continuous casting mold is especially constructed for use with a vaporizable coolant which is nonreactive with the molten metal being cast or the mold itself and includes an inner mold body having a longitudinal solidification chamber therethrough, an intermediate mold body surrounding and spaced from the inner mold body to define an annular cooling chamber therebetween and an outer mold body surrounding and spaced from the intermediate mold body to define an annular manifold chamber therebetween. Coolant access means associated typically with the outer mold body provides entry for coolant into the manifold chamber. The intermediate mold body includes coolant access means adjacent one end of the mold and coolant discharge means adjacent the other end so that coolant from the manifold chamber enters the cooling chamber at one end of the mold and flows around and along the length of the inner mold body to the other end where it is discharged, the coolant absorbing heat from the inner mold body and solidifying metal therein as it travels through the cooling chamber.
