Width measuring device of hot-state continuous casting sheet billet for hot rolling

The utility model relates to the technical field of steel rolling mechanical equipment, in particular to a hot-state continuous casting slab width measuring device for hot rolling, which is characterized in that a slab passes through the middle of a protective device, so that the other ends of a first roller and a second roller are rolled on the slab; the first pressure sensor and the second pressure sensor are used for detecting the extrusion force of the first rolling wheel and the second rolling wheel to the plate blank correspondingly, and when the width of the plate blank changes, the extrusion force detected by the first pressure sensor and the second pressure sensor changes; the first pressure sensor and the second pressure sensor transmit detection data to a display on continuous casting slab production equipment, so that a worker can calculate the width change of the slab according to the extrusion force detected by the first pressure sensor and the second pressure sensor, and the worker can convenie
