A molten metal surface level in a mold type continuous casting machine is controlled with an improved responsiveness and high accuracy by means of a novel electrical control system comprising a servo mechanism incorporating a microcomputer or the like, means for processing an input signal thereto from a detector means at the molten metal surface to feedback thereto a controlling output and, optionally, an ITV camera for photographing the molten metal surface portion to produce binary-coded signals through a suitable processing means so that the molten metal surface level can be detected and controlled with higher accuracy. |
