Abstract

A method analyzes global average grayscale change of tundish ink tracing experiment. The method includes the following steps: building a water model based on a prototype size and production parameters of a tundish; carrying out experiments by using the water model to obtain a video file of the ink tracing; processing the video file and extracting a characteristic curve of a global average grayscale changing with the time; analyzing the characteristic curve, and extracting a global peak grayscale time, a global tracer residual volume and a global emptying time as indicators for evaluating a tundish structure and flow characteristics of the tundish structure.
