Molten metal level measurement for immersion nozzle and molten metal level measuring device

摘要

Without accompanying troublesome job, the melting metal level measurement equipment which measuring the level of the melting metal at high precision it is possible, uses the electromagnetic wave is offered. The device, the said dipping nozzle (100) with being separated by the longitudinal direction of the dipping nozzle as one unit, mutually the 1st and 2nd conductive part which consists of the carbon which was formed (1001A and 1001B) with, in the said 1st conductive part, transmits the signal which forms the 1st pseudo random signal, the said 1st conductive part, the melting metal and the said 2nd conductive part receives the signal which is spread from the said 2nd conductive part, the signal which is received and, frequency of the pseudo random signal barely differs in the pattern which is identical with the 1st pseudo random signalMultiplying the 2nd pseudo random signal, it calculates multiplication value, uses the signal or the said multiplication value of the said multiplication value and the range measurement section which measures the propagated distance of the said signal from time serial pattern of the signal which is generated (200,300) with, it has.
