MOLTEN STEEL FLOW-STATE ESTIMATING METHOD AND FLOW-STATE ESTIMATING DEVICE

摘要

The method for estimating the flow state of molten steel is a method in which the CPU 113 calculates the temperature distribution of the molten steel measured by the thermocouple 41 at the position where the thermocouple 41 in the mold of the continuous casting machine is installed, An external force is applied to the vicinity of the discharge port of the nozzle for discharging the molten steel into the mold and the flow state of the molten steel is calculated in the state where the external force adjusted to compensate for the error is applied, And estimates the flow state of molten steel.
