Synopsis : Two sets of hot strip profilemeter installed at Chiba Works; a No.1 for No.2 mill in March, 1979, a No.2 for No.1 mill in March, 1980; feature a combination of two high-precision X-ray thickness gases - the fixed type and the scanning type. The measuring system has been operating smoothly, contributing greatly to a high-precision measuring of strip crown and 'high spot'. The results of tests on this development are summarized as follows: (1) The profilemeter can detect 'high spots' of more than 4Κm in height and 5mm in width in off-line tests and those of more than 5Κm in height and 10mm in width during rolling. (2) It can measure the strip crown and wedges at an accuracy of within }10Κm. (3) Regardless of strip profile changes during the scanning of the gage, the profilemeter output shows good correspondence to values measured by the Α-ray thickness gage in the subsequent line. |
