Description

Technical Field

[0001] The utility model belongs to the technical field of steel smelting, and in particular relates to a thickness detection device used in hot-rolled plate production. Background Art

[0002] Hot-rolled plate, also known as hot-rolled steel sheet and strip, is made from continuous casting slabs or slabs. After heating in a walking beam furnace and descaling with high-pressure water, the roughing mill processes the material. The roughing mill then undergoes head and tail trimming before entering the finishing mill, where computer-controlled rolling is applied. After final rolling, the material undergoes laminar cooling (with a computer-controlled cooling rate) and is coiled in a coiler to form straight coils. Straight coils often have tongue-shaped or fishtail-shaped heads and tails, poor width accuracy, and often exhibit edge defects such as wavy edges, folded edges, and pyramidal shapes. During the steel rolling process, the quality of hot rolling, especially the uniformity of the plate thickness, directly impacts the quality and process of cold rolling.

[0003] At present, the thickness measurement of hot-rolled steel plates mainly relies on manual measurement. During manual measurement, there are great safety hazards due to the extremely high temperature of the workpiece. At the same time, frequent measurement needs and extremely high ambient temperatures make the labor intensity high and the working environment poor. Some laser sensors are used for non-contact measurement. During measurement, the red light emitted by the high-temperature plate being measured affects the measurement accuracy of the laser sensor. The extremely high ambient temperature reduces the life and measurement stability of the laser sensor. Utility Model Content
