Heavy plate rolling mill - has easy plate identification with coloured ink jet groups for surfaces and edges

摘要

A roller train for producing heavy plate has a device for applying identification numbers to the sections of plate. It consists of a roughing frame (1), finishing frame (2), cutter (3), heat straightening section (4), cooling bed (5), trimmer (6), transverse cutter (7) and store (8). It may also have an annealing furnace (9), additional cutter (10), and an associated store. The use of edge marking enables each plate to be identified easily in each pile using decoding templates for manual or automatic identification. The surface marker (11) is a conventional automatically controlled ink jet pistol group positioned before or after the straightening device (4). An edge marker (12), also consisting of a group of coloured ink jet pistols, may be placed in front of or behind the transverse cutter (7). A diode camera reactor (14) is placed near the store (8).
