Abstract

The invention discloses a ray-type thickness gauge and a calibration method thereof. The thickness gauge comprises a ray source, a ray detector, a pre-amplification circuit board, a control cabinet, a terminal display and operation device, and a C-shaped rack, wherein the ray source is arranged at the lower part of the throat gap of the C-shaped rack; the ray detector is arranged at the upper part of the throat gap of the C-shaped rack; a to-be-measured metal belt penetrates through the throat gap of the C-shaped rack; the pre-amplification circuit board is connected with the control cabinet; and the control cabinet is connected with the terminal display and operation device, and is used for calculating and displaying a thickness and receiving the instruction of an operator. According to the calibration method of the thickness gauge, the measuring accuracy after fast calibration can reach the precision level of a just calibrated thickness gauge, so as to save time spent in re-calibration, eliminate an error caused by anthropic factors during calibration carried out by the operator, and provide a high-precision thickness measure value for the thickness control system of a rolling mill. Therefore, the production efficiency of the rolling mill can be improved; and the tolerance requirement of the metal belt rolled by the rolling mill can be guaranteed.

Description

technical field [0001] The invention relates to a measuring device on a metal strip rolling production line, in particular to a ray-type thickness gauge and a correction method thereof, belonging to the technical field of metal strip rolling in the metallurgical industry. Background technique [0002] In the rolling production of metal strips, in order to ensure that the rolled strips meet the thickness tolerance requirements, a thickness measuring instrument with stable performance is required. Because of the constraints of many factors in the production site environment, such as temperature, humidity, water vapor, oil gas, oil pollution, vibration, etc., will have an adverse effect on the measurement accuracy of the thickness gauge, which will cause its measurement error to increase. [0003] In order to ensure the measurement accuracy and stability of the ray thickness gauge, predecessors have done a lot of work, examples are as follows: [0004] (1) In the 1970s, a dual...
