Protective device and method of hot rolled strip steel lower surface detecting device

Abstract

The invention relates to a protective device and method of a hot rolled strip steel lower surface detecting device and belongs to the technical field of hot rolled strip steel production devices of the metallurgical industry. According to the technical scheme, a roller bed overturning plate (2) is arranged between a conveying roller bed A (20) and a conveying roller bed B (30), a detecting camera(12) and an imaging light source (13) are arranged in a glass protective cover (16), the strip steel lower surface detecting device is arranged below the roller bed overturning plate (2), a protectiveplate (5) is arranged below the conveying roller bed A (20), a protective plate water discharge opening (6) is arranged on the protective plate (5), a water accumulating groove (7) is arranged belowthe conveying roller bed B (30), a high-pressure air spray nozzle (11) is arranged below the protective plate (5), a roller bed roller groove (3) is arranged below a conveying roller in the conveyingroller bed B (30). The protective device and method of the hot rolled strip steel lower surface detecting device has the beneficial effect that the situation that cooling water is splashed to the glass protective cover of the strip steel lower surface detecting device, so that clearness of the imaging view field of the camera is influenced is avoided.

Description

technical field [0001] The invention relates to a protective device and a protective method for detection equipment for the lower surface of hot-rolled strip steel, belonging to the technical field of hot-rolled strip steel production equipment in the metallurgical industry. Background technique [0002] In the production process of hot-rolled steel strip, it is necessary to detect the lower surface of the strip to distinguish the surface quality defects of the strip. [0003] The detection equipment for the lower surface includes a detection camera and an imaging light source. The detection camera and the imaging light source are set in the glass protective cover and installed in the equipment room below the output roller table of the hot-rolled strip steel production line. The roof of the equipment room is provided with holes. The imaging light source The emitted light passes through the glass protective cover and shines on the lower surface of the hot-rolled steel strip t...

AI Technical Summary

Problems solved by technology

Since the detection equipment for the lower surface of the strip is installed in the equipment room below the output roller table of the hot-rolled strip production line, it is more susceptible to the influence of splashed cooling water, and scattered water droplets fly onto the glass protective cover of the detection equipment for the lower surface, especially The splashing of water droplets is more serious when producing checkered plates and when the strip shape is poor

Since the industrial cooling water contains a variety of additives and contains a lot of oil and impurities, when the water droplets splash on the glass protective cover, the water droplets evaporate and form spots, which affect the clarity of the camera's imaging field of view

Therefore, in the production of hot-rolled strip steel, it is usually required to manually wipe the glass protective cover within 2 hours. It is difficult to completely remove the spots of grease and additives, and frequent wiping is easy to scratch the protective glass. The amount of labor increases, and there are also major safety hazards, and the thorough cleaning of the protective glass cannot be guaranteed.
