A system and method for detecting uniformity of surface roughness of cold-rolled sheet

Abstract

A system and method for detecting the uniformity of the surface roughness of cold-rolled sheets proposed by the present invention belong to the technical field of cold-rolled sheet detection. The system includes: an image acquisition module and a uniformity detection host, and the image acquisition module and the uniformity The data connection of the detection host; the image acquisition module is fixedly installed above the conveying roller table of the rolling mill, and is used to collect the image information of the surface of the cold-rolled plate and upload it to the uniformity detection host. The uniformity detection host is used to: issue acquisition instructions to the image acquisition module according to the preset time interval; generate the topography curve of the image according to the image information, and calculate the average roughness of the image; Roughness, to determine the actual roughness of the current cold-rolled sheet; according to the actual roughness, the consistency detection of the subsequent calculated image average roughness is carried out. The invention can effectively improve the detection speed and accuracy of the detection of the uniformity of the surface roughness of the cold-rolled plate.

Description

technical field [0001] The invention relates to the technical field of cold-rolled sheet detection, and more specifically relates to a detection system and method for the uniformity of the surface roughness of a cold-rolled sheet. Background technique [0002] Cold-rolled thin steel plate is the abbreviation of ordinary carbon structural steel cold-rolled plate, also known as cold-rolled plate, commonly known as cold-rolled plate, sometimes mistakenly written as cold-rolled plate. The cold plate is a hot-rolled strip of ordinary carbon structural steel, which is further cold-rolled into a steel plate with a thickness of less than 4mm. Due to rolling at room temperature, no iron oxide scale is produced. Therefore, the cold plate has good surface quality and high dimensional accuracy. With the addition of annealing treatment, its mechanical properties and process properties are superior to hot-rolled thin steel plates. In many fields, especially In the field of home appliance...

Problems solved by technology

However, this detection method requires multiple data comparisons and summaries, and the amount of calculation is large.

Moreover, all data are judged on the basis of roughness quality standards, which cannot intuitively reflect the actual state of the surface roughness of cold-rolled sheets
