Abstract
PURPOSE: To achieve the prevention of the reduction in the accuracy of the captioned detection by calculating the point of intersection with the cooling water temperature of the mold as a molten steel level from the linear expression approximated by a number of measured values of the portions where the temperature gradient near the meniscus is sharp.
CONSTITUTION: The level of the molten steel 2 poured from tundish into a mold 1 is obtained by the device consisting of the output multiplexer 3 for changing- over of the output signals V1WVn of thermocouples T1WTn, an A/D converter 4, arithmetic processing unit 5 and D/A converter 6. First, the unit 5 performs the operations of Vi+1-(Vi+β)≥0 subsequently with the outputs V1WVn and selects the thermocouples near the meniscus. β is an offset signal. If the temperature distribution is like the curve (a), as a result of this, the point where the straight line passing the three points (Vi-1, yi-1), (V1, yi), (Vi+1, yi+1) intersects with water temperature Vw is calculated as the level y and is fetched as the level signal from the converter 6.
