hot water surface level and measuring method of mold powder thickness of the molten metal in the continuous casting mold

摘要

PROBLEM TO BE SOLVED: To provide a method capable of continuously measuring a molten metal surface level of molten metal in a casting mold for continuous casting from an initial stage of injecting the molten metal, and capable of also continuously measuring a mold powder thickness.;SOLUTION: A method according to the present invention calculates a thickness of mold powder P inputted on molten metal based on a measured value of s first level gauge and a measured value of a second level gauge, by outputting a molten metal surface level measured value measured by the first level gauge as a molten metal surface level, after the molten metal surface level reaches the lower limit, by outputting the molten metal surface level measured value measured by the second level gauge as the molten metal surface level until the molten metal surface level reaches the lower limit of a measurement range set in the first level gauge, by using the electromagnetic type first level gauge 10 for measuring the molten metal surface level of the molten metal S in the casting mold 50 for the continuous casting and the microwave type second level gauge 20 capable of measuring the molten metal surface level of a range overlapping with a measurement range set in the first level gauge and a range lower than this range.;COPYRIGHT: (C)2014,JPO&INPIT
