Abstract
PURPOSE: To obtain steel plates free from strain after processing at low cost, by disposing a plurality of plastic adjusting machines having rolls of specified diameter and number arranged in specified configuration.
CONSTITUTION: A hot rolled coil 2 from a coil opener 1 is inserted into plastic adjusting machines of the first stage consisting of a plurality of rollers 4, 5, 6, etc. disposed in specified diameter, number and configuration as designated sepaarately through fitting part 3, pinch roll 9, and others, and plastic adjustment is performed by repeating reverse plastic deformation, and is then inserted into roll groups 14, 15, 16 of plastic adjusting machines 13 of the second stage through side trimmer 10. By repeating reverse plastic deformation with a drum roll having a curvature corresponding to the internal stress distribution curve of a hoop steel 2, the plastic adjustment is accomplished, and steel plates are obtained by cutting to specified dimension by a die set shear 17. In this method, the reduction ratio is lower than in the conventional method, and strain after processing does not occur, and, hence, the job efficiency is improved. In addition, depending on the thickness of the hoop, it is possible to adjust the reduction ratio freely as desired.
