Crop end cutting of a moving metal product prior to a hot rolling operation with precise determination and control of the ideal cutting line for removal of the crop end

摘要

Cutting a crop end of a moving metal product before hot rolling consists of: (a) acquiring some successive images of the crop ends of the product; (b) regulating the threshold of luminosity by means of a system for the treatment of the images to distinguish the environment around the profile; (c) determining the ideal cutting line for completely and strictly eliminating the crop end; (d) determining the speed of acceleration of the products in a manner to evaluate the displacement rules; (e) determining the ultimate instant at which the ideal cutting line arrives at the elevation of a cutting device; (f) starting the cutting at that ultimate instant, : An independent claim is also included for a device for putting this method of cutting into service.
