Ingot Mold Metal Level Control Technologies

From automated systems to simple mechanical devices, Wagstaff offers a metal level control technology to suit your needs.

The precise control of the metal level in ingot molds is a necessity in the efficient casting of aluminum ingots, influencing safety of the process, equipment longevity, and product quality.  Wagstaff offers a variety of sensors and actuators to reliably perform this function with the highest level of accuracy.

Wagstaff Metal Flow Control Valve Actuator with Wagstaff Inductive Sensor

The Wagstaff mold metal level controller with inductive sensor provides a robust, reliable way to measure molten metal in the mold bore.  This sensor combines the proven technology of the Wagstaff inductive MMLC with pin positioner in a smaller, lighter, more functional, and easier to use sensor package than Wagstaff's previous inductive sensor/actuator bundles.  The versatile separated sensor and actuator arrangement improves the ease of maintenance and setup, enables level sensing into smaller mold sizes, and provides an extended measuring range of 304.8 mm.

Wagstaff Steady-Eddy

The Wagstaff Steady-Eddy mold metal level control device is ideal for less demanding ingot casting applications.  The Steady-Eddy incorporates a four-bar mechanism that produces near linear movement of the float in the mold.  This type of mechanism reduces the error created when the float does not move vertically in the mold cavity.  The pivot points have stainless steel shoulder bolts and bearings with a very low coefficient of friction.  After a steady state setting is achieved, the pin preset position can be easily set, and allows for hands-off control thereafter.

Floats and Spouts

For an economical and simple operation, floats and spouts can be used to control the metal level in ingot molds.  This application is effective when low metal levels are not required.
