Abstract
Abstract A method and apparatus for continuously measuring the temperature of a metal rod which is continuously cast and as the rod is fed away from its associated casting mold includes a rotating cylinder or wheel having a plurality of temperature sensors arranged at spaced locations around the circumference which engage against the rod at one or more particular locations. The temperature which is sensed is advantageously transmitted either by wire or radio wave to a control station where the information is employed for the regulation of the feeding and molding and subsequent forming of the continuously cast rod. The device advantageously includes an electrical temperature feeler having one feeler element which is adapted to be connected to a segmental contact and another feeler element adapted to be connected to another segmental contact within the cylinder which moves with its circumference in engagement with a side of the cast rod which is formed. A electrical circuit is provided with means for determining the maximum temperature of each of the feeler elements or a specific temperature as desired and for amplifying the indicated value in transmitting it to a control station as desired. The cylinder may be arranged to roll against the rod, for example, at the location of the so-called sump tip at which the entire rod cross sections begins to solidify.
