Abstract
PURPOSE: To perform automatic control of molten metal level in a mold at low cost, by burying a temperature measuring element in the inner wall of a mold for continuous casting at a height where the molten metal level reaches the critical level of the mold when the output of the element indicates the maximum value.
CONSTITUTION: A temperature measuring element 7 is buried in the inner wall of a mold 3 for continuous casting at a position lower by H from critical level Lr of the mold. When the molten metal level in the mold 3 reaches first and second specified levels Lu, Ld, a manual commanding circuit 14 is operated on every occasion, and sampling command (i) and holding command (j) are input in a sampling circuit 8 and a holding circuit 9, and the outputs of the temperature measuring element 7 corresponding to each level are held. Then, a selector 15 is changed to the automatic operation side, and the molten metal level and reference level Lo are compared and processed in a comparator circuit 12. Depending on whether the difference signal is larger or smaller than Lo, an opening or closing signal O for a slide valve 2, or an accelerating or decelerating signal (n) for a pinch roll 4 in proportion to the magnitude thereof is output from a molten metal amount control device 13, so that the molten metal level may be always maintained at the reference level Lo.
