Abstract

PURPOSE:To obtain a wide measurement range from the start of casting in a narrow space between a tundish and a mold, by suspending an electrode with a wire and by measuring the extent of taking-up and the extent of rewinding of the wire through a potentiometer. CONSTITUTION:Molten steel 21 is supplied from a tundish 24 into a casting mold 23. With the electrodes inserted into the lower region of the flux floated on the surface of molten steel 21, the change in electric resistance due to the temperature change in the insertion position because of the rise of the molten steel level is detected with the electrodes 30. A drum 32 is rotated in either sense of rotations by a motor 31 to displace the electrodes 30 up or down so that the detected value with the electrodes 30 is constant all the time. The extends of taking-up and rewinding of wire 29 due to the rotation of a drum 32 is determined with the potentiometer 33, and from this measured value the height of electrodes 30 is detected to determine the level of molten steel.
