Abstract

See full text

The invention is directed to an apparatus and method for controlling the overflow of molten material from a receptacle for the purpose of achieving more uniform casting of the molten material. The apparatus and method utilize a force detector able to detect the change in the buoyant force exerted on a submersible body lowered into a molten material. A differentiating means, a control means, and a drive means are responsive to the force detector, whereby a constant rate of change of buoyant force is translated into a uniform rate of overflow of molten material delivered to a heat extracting substrate for solidification.
