Abstract

The invention discloses a steel coil end portion quality detection method. The detection method comprises the following steps: arranging an imaging device at each of two sides of a steel coil convey chain, respectively shooting the end portions at two sides of the pass-through steel coil through controlling the imaging devices by PLC to obtain images, and processing and comparing the images through an image processing server to realize defect determination; and querying historic image information and the defect detection result in real time through an image operation terminal. The invention also discloses a steel coil end portion quality detection system. The detection system and the detection method can mitigate the labor intensity and damages of high temperature radiation to human bodies, and effectively avoid the subjectivity and false negatives caused by visual inspection, so various defects existing in the end portions of the steel coil are effectively and objectively detected and assessed, and the qualified rate of finished steel coil is guaranteed.

Description

technical field [0001] The invention relates to an imager, and more specifically relates to a steel coil end quality detection system and method. Background technique [0002] In the hot rolling and continuous rolling mill production line of iron and steel enterprises, the surface quality of the strip steel and the forming quality of the steel coil are usually inspected in the coiling area, that is, the surface quality of the strip steel is inspected online before coiling, and the quality of the coil is inspected after coiling. Some steel coils are uncoiled for inspection confirmation and sampling. The former is to use machine vision and image pattern recognition technology to detect the surface defects of hot-rolled strip steel online, while the latter is to use the quality inspection unit to assist manual offline inspection and sampling. However, for the defects at the ends of both sides of the steel coil, it can only be inspected by manual visual inspection at present. ...
