Tandem rolling mill output method and installation with coiling carousel coupled with on-line inspection

摘要

Method for coiling and on-line inspection of a continuously-rolled metal strip, involving continuous coiling on at least one mandrel of a coiling station, preferably of carousel type, wherein: the strip is cut by a shears situated before the coiling station, advances over a certain length on an insertion table so as to at least partially cover this table and is then cut a second time by the shears in order to obtain a specimen; —the coiling performed on the mandrel is terminated and the coil is discharged from the coiling station; at the same time, the insertion table bearing the specimen is moved parallel to the rolling-coiling line until it lies in an inspection line comprising an inspection table; —the specimen is inspected on the inspection table so that faults can be detected; —once the specimen has left the insertion table, the latter is placed back in the rolling-coiling line.

主权项

1. An installation for coiling and on-line inspection of a continuously-rolled metal strip to be coiled, comprising, downstream from a last rolling stand, in a main line, a first shears (4) for successively cutting the strip a first time and a second time after the strip has advanced over a certain length to obtain a strip specimen cut in a strip tail and having a predetermined length, a coiling station (3) having at least one coiling mandrel (10, 20) for coiling the strip, and an inspection table (8) for detecting faults on at least one of the faces of the strip specimen, wherein the inspection table (8) is part of a separate, inspection line, and parallel to the main line, and wherein the installation further comprises an insertion table (6), initially situated between the shears (4) and the coiling station (3) in the main line and able to be moved by means of a conveyor (15) from said main line toward the inspection line while being parallel to the main line so that the insertion table (6) allows to transport, toward the inspection table (8), the strip specimen cut in the strip tail and having a predetermined length, said predetermined length corresponding at least partially to the length of the insertion table (6).
