Abstract: A casting mold including a copper plate and a plurality of optical fibers, having a plurality of temperature measuring points for the copper plate while casting. Molten metal is cast into the mold along an axis of, the optical fibers built-in the plate. A method for detecting temperature distribution of a molten metal in a casting mold having at least one copper plate, including determining by calculation or measurement an ideal molten flow of the metal, building-in a plurality of optical fibers into the copper plate based on flow, arranging the optical fibers inside at least the upper part of the copper plate, receiving the measurements of temperatures, and comparing the measurements of temperatures with a calculated/measured distribution of an ideal molten flow.
