[0031] This all significantly affects the overall operating cost of the rolling mill
[0032] Furthermore, grinding also takes time, and thus removal of useless material is also expensive in terms of time, machine and operator

Embodiment Construction

[0045] With reference to the figures, a method 100 for classifying the defects in question and performing lamination cylinder grinding falls within the scope of a process 200 for managing from measurement data revealed during a first phase of said process 200 Repair of damage to lamination cylinders.

[0046] The method 100 for classifying defects and performing lamination cylinder grinding according to the invention enables this process 200 to be fully automated, since there is no need to resort to the intervention and evaluation of an expert operator.

[0047] The management process for repairing damage to the lamination cylinder is preferably based on a joint analysis of results obtained from geometric analysis and at least non-destructive control measurement and diagnostic means.

[0048] This measuring and diagnostic device is preferably implemented on the grinding machine.

[0049] For example, the process begins by obtaining 210 starting data such as geometric properti...

Abstract

Method (100) for the classification of defects and running of the grinding of lamination cylinders comprising the following phases which consist in: a) identifying defect areas in a map illustrating a plurality of surface measurements of a cylinder; b) calculating, for each defect area identified, a plurality of typical parameters; c) identifying a type of defect associated with said defect areas identified, on the basis of said parameters calculated; d) determining (120) an acceptability threshold of the specific defect for each type of defect identified; e) defining (130) a corrective action for each defect area on the basis of the comparison between said acceptability threshold associated with the type of defect of said defect area, and a measurement of said plurality of surface measurements of the cylinder associate with said defect area; f) determining (140) grinding parameters on the basis of said surface measurements of said cylinder, if the corrective action defined in phase c) is a grinding operation to remove the defects.

Description

technical field [0001] The invention relates to a method for classifying defects and performing lamination cylinder grinding. Background technique [0002] Lamination cylinders are extremely expensive mechanical components that are particularly critical to obtaining the high quality properties of panels and other steel frame products. [0003] Cylinders are moving elements in direct contact with the product, so their degree of wear is extremely high and their operation is particularly expensive. In turn, their breakage can cause considerable production losses. [0004] Due to the critical nature of these elements and their cost, areas associated with lamination lines for their reprocessing and grinding or reprocessing are envisaged in steelworks. [0005] This section called "Roll Shop" includes a number of grinding machines, a movement and storage system for the cylinders, and also means for measuring the geometrical and diagnostic properties of their defects produced by ...
