СПОСОБ И УСТРОЙСТВО ДЛЯ КОНТРОЛЯ ТЕХНОЛОГИЧЕСКОГО ПРОЦЕССА ИЗГОТОВЛЕНИЯ ГОРЯЧИМ СПОСОБОМ ТРУБ ИЗ СТАЛИ

摘要

Monitoring the finishing process in the manufacture of hollow steel pipes comprises completely thermographically determining the heat radiation of at least one defined section of the outer surface of the pipe (4) and comparing the heat image obtained with a reference image of an already prepared pipe of the same steel quality class and dimensions. A deviation of the heat image produced on a determined measuring site on the pipe is used to compare with the heat image of the same measuring site to judge the process condition. An independent claim is also included for a device for carrying out the monitoring method comprising a thermal camera (1), a heat imaging camera (3) and an evaluation unit.
