Nozzle assembly design for a continuous alloy production process and method for making said nozzle.

摘要

A nozzle assembly design (18,20,22) and a method for making the nozzle assembly, as well as a method for controlling a continuous skull nozzle process employing the nozzle assembly are provided wherein the cooling heat transfer coefficient at the nozzle is increased to maintain a steady-state solidified layer of a noncontaminating liner material, the cooling heat transfer coefficient being increased by reducing the contact resistance between a nozzle outer wall member (18) and an inner liner (22) made of the noncontaminating material, the reduction in contact resistance being achieved by shrink-fitting the nozzle outer wall member around the inner liner to increase the contact pressure between those members. <IMAGE>
