Abstract: A method of controlling molten metal flow and an electromagnetic brake system for a metal-making process, including: a first magnetic core arrangement having a first and second long sides with Nc teeth, and arranged to be mounted to opposite longitudinal sides of an upper portion of a mould, a first set of coils, each being wound around a respective tooth of the first magnetic core arrangement, and Np power converters, with Np being an integer that is at least two and Nc is an integer that is at least four and evenly divisible with Np, wherein each power converter is configured to feed a DC current to its respective group of 2Nc/Np series-connected coils.

Abstract: A method of determining a temperature distribution in a mold plate of a mold for a metal-making process, wherein the method includes: obtaining a temperature value from each of a plurality of temperature sensors arranged in the mold plate, each temperature sensor being spaced apart from a respective reference point in the mold plate, determining for each temperature value a reference point temperature value at the corresponding reference point using either a respective linear function or a respective non-linear function, wherein a correction factor and correction term of the linear function or a set of parameters in a general non-linear formulation of the non-linear function is obtained from a plurality of initial temperature relationships, wherein each initial temperature relationship is between a simulated temperature at the corresponding temperature sensor in the mold plate and a simulated temperature at the corresponding reference point in the mold plate, each simulated temperature being obtained based on a respective simulation of a model of the mold plate for a unique mold plate condition where the thermal boundary conditions of the mold plate have been completely, explicitly and uniquely stated, and obtaining an estimated temperature distribution at the reference points in the mold plate by means of the reference point temperature values.

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.
