摘要

PROBLEM TO BE SOLVED: To provide an estimation and its display method for temperature distribution in time series and flow rate vector distribution of flow in time series in the entire region inside a mold of a continuous casting machine.;SOLUTION: The temperature distribution in the region where a temperature sensor inside the mold is not attached in each measuring time, is estimated by interpolation or extrapolation of data in time series obtained by temperature sensors attached inside the continuous casting mold, and the estimated temperature distribution is displayed in time series into a frame. The distribution of flow rate absolute values is estimated based on the estimated temperature distribution, and the distribution of flow rate vectors is estimated based on variance of temperature distribution data between a casting direction and a direction perpendicular to casting, and variance of flow rate absolute value distribution data between two sequential times, and then both are displayed in time series into a frame.;COPYRIGHT: (C)2003,JPO
