摘要

An experimental method which has been developed makes use of thermal vision to study the temperature of metal during hot shaping. The method also uses a computer to analyze video images and does not require costly equipment. It is suited for noncontact measurement of the surface of heated semifinished products within the range 400-1600 deg C. The article reports the results of commercial trials in which the thermal state of semifinished products was examined during radial-shear rolling, forging, the piercing of shells, and the rolling of tubes on a unit equipped with a Pilger mill.
