Abstract

1503864 Measuring the level of molten metal CONCAST AG 28 May 1976 [30 May 1975] 22475/76 Heading G1A [Also in Division H5] In a device for measuring the level of molten metal in a continuous casting mould an elongated radio-active radiation source 2 is centrally positioned in a holder 5. The source 2 is behind a rotatable cylindrical plug 6 that has a diverging slot 10 in it which is aligned with the source 2 during measurement. In use radiation passing via the slot and the mould 1 is received by a detector 4. After use, the plug 6 is rotated by a lever F to a safe position, Fig. 2, wherein the slot is not in alignment with the source 2. The plug may be spring-biased into this latter position. The holder and plug may be designed so that the outer boundary of the crosssection of the holder substantially defines an isodose line.
