Research on the Temperature Distribution near the Surface of Long-Shaft Heavy Forging

Abstract:

The precise edges of forging should be extracted from the image when measuring the dimensions of high temperature forging based on the non-contact image measurement technique. It is difficult to distinguish the forging boundary precisely due to the continuous variation of the air temperature near the forging. The two-dimensional simplified cross-section models, including the squaring, chamfering and rounding models, were established by the symmetrical modeling method. The air-cooling process from 1200°C to 800°C of high temperature long-shaft heavy forging was simulated based on ANSYS software. The variation regularities of temperature with the distance and time were obtained, which provides a theoretical basis to determine the edges of high temperature objects in non-contact measurement.
