Description

Technical Field

[0001] The utility model relates to the technical field of surface detection of aluminum sheet and strip, in particular to an inspection table for an aluminum sheet and strip rolling mill. Background Technique

[0002] The cold rolling workshop of aluminum sheet and strip is an important place for producing aluminum sheet and strip products. The main production process of cold-rolled aluminum sheet and strip is as follows: ingot casting (homogenization) → surface milling and edge milling → heating → hot rolling → edge cutting and head and tail cutting → coiling → annealing → cold rolling → annealing → cold rolling → inspection → finishing → oiling and packaging. Among them, cold rolling is the final step of aluminum sheet and strip rolling. Cold rolling refers to the rolling production method below the recrystallization temperature. The characteristics of cold rolling are: high dimensional accuracy and good surface quality of the sheet and strip; more uniform organization and performance of the sheet and strip; different states of products can be obtained by combining with heat treatment; thin sheet and strip that cannot be rolled by hot rolling can be rolled.

[0003] Due to the high requirements for the surface quality of aluminum alloy sheet and strip products in the market, the surface of cold-rolled aluminum sheet and strip products should be detected after cold rolling. The general detection items are: thickness, width, flatness, residual amount of surface process oil, surface roughness, etc. According to the usage of users and different technical standards adopted during product production, there are different focuses. After the aluminum sheet and strip rolling is completed, it will be directly coiled into an aluminum coil on the coiling side of the rolling mill. The traditional surface detection of aluminum sheet and strip is to detect the aluminum coil by workers after rolling. During the detection process, usually only the outermost layer of the aluminum coil can be detected, so the accuracy of the detection data is relatively low, and the surface quality problems of the inner layer of the aluminum coil cannot be fully reflected.
