A wire thickness meter is known. Recently, new gamma-ray thickness gauges have been installed in new mills for thick steel plates, but as is well known, gamma-ray thickness gauges are expensive, and in older mills, workers still have to use a micrometer or other device to measure the thickness by hand. The actual situation is that the plate thickness is measured. Needless to say, measuring plate thickness by hand on a hot rolling line is extremely dangerous work.
It's inefficient.

定するようになっている。Structure of the Invention The steel plate thickness measuring device according to the present invention is a device that measures the thickness of the four circumferential edges of a steel plate on a conveyance line, and has a gate-shaped structure that extends over the steel plate conveyance line. A running trolley that can move in a direction perpendicular to the conveyor line is installed on the mount, and the measuring instrument, which is vertically attached to this running trolley so that it can rotate 270 degrees at a fixed position, is attached to the plate by clamping the side edges of the steel plate from above and below. It is equipped with a distance measuring device (e.g., Magnescale) that is equipped with a pair of measuring rods that can be raised and lowered, and that measures the distance between the probes provided at the tips of both measuring rods by the amount of elevation of the measuring rods. The thickness of the steel plate on the conveyance line is measured by sandwiching the steel plate between two contacts of a pair of measuring rods and detecting the distance between them using a magnescale or the like.

。As described above, this invention device measures a steel plate by sandwiching a steel plate with a pair of contacts that can be moved across the width of the plate and can be raised and lowered in a fixed position and rotated, and the distance between the contacts is detected and measured using a magnescale or the like. Since this method completely automates the conventional manual measurement of the thickness of the four circumferences of a steel plate, it is possible to safely and accurately measure the thickness of a thick steel plate in a hot rolling line. Furthermore, since the device itself can be manufactured using inexpensive components, the equipment investment is also lower than that of a gamma-ray plate thickness measuring machine. Furthermore, since the plate thickness is only measured by contacting the thick steel plate while the plate is stopped, there is an advantage that the life of the contactor is long and the tip needs to be replaced less frequently. Furthermore, even if the steel plate is running diagonally, it can be measured because the edge of the plate can be automatically detected before measurement.
