Abstract

PURPOSE:To measure the thickness of the rolled material between the stands, by installing either the radiation detector or the radiation generator in the hollow roll which makes the rolling contact with the rolled material. CONSTITUTION:A hollow roll 1, to make a rolling contact with the rolled material ST, is installed between two stands of the hot continuous rolling mill; a radiation generator 2 and a radiation detector 3 are installed facing each other interposing the circumferential wall of the hollow roll 1 or the traveling zone of the rolled material ST, either one of them, the radiation detector 3 for example, is located within the hollow roll 1. Then, the circuits of the X-ray generator 2 and the X-ray detector 3 are actuated in order to irradiate X-rays upon the rolled material ST and the hollow roll 1; the irradiated X-rays are caught by the X-ray detector 3 which then produces a voltage signal corresponding to the dose of detected X-rays and inputs it to the adder 5. The deviation amplifier 7 economically produces the deviation of the thickness of the strip to be the object of measurement from the reference signal, depending on above stated voltage signal and the reference signal preset in the set point adjuster 6; hereby, the thickness measurement or the thickness control for the rolled material ST is carried out.
