ABSTRACT:
A process and apparatus for the control of a continuous process for casting metal. The apparatus includes a mold cavity (8) formed by upper and lower movable belts (2 and 3, respectively) and side dams (6 and 7) and including an inlet opening (9). Molten metal (11) is flowed to the inlet opening from a source (14) by conduit (12) connecting with an outlet (13). An opto-electronic device (17, 51) provides a signal which is a function of the level of the molten metal at a zone (FIG. 4) within the mold cavity and a circuit (40) responsive to the signal controls the position of a plug (15) relative to the outlet to control the flow of molten metal. The opto-electronic device includes a photosensitive element (23, 57) whose sensitivity lies essentially to radiation within the visible spectrum and only weakly responsive to infra-red radiation.
