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 mat...
A flow rate control apparatus for the casting of filaments and sheets, said apparatus having a receptacle for containing a molten material, the receptacle having a lip over which the molten material can flow when its free surface is raised to a level above the lip, the flow control apparatus comprising: (a) at least one movably mounted submersible body mounted for lowering into and raising out of the molten material in the receptacle for variably displacing molten material; (b) a drive means drivingly linked to the body for raising and lowering the subme...
