REPEATER FOR ROLLING ANGLE STOCK

摘要

PURPOSE:To roll satisfactorily an angle stock by twisting successively 180 deg. the angle stock emitted from a rolling mill by means of inlet side and outlet side guide twist rollers and repeater guide rollers to send the angle material to the succeeding rolling mill and absorbing a coil break of the stretched member by the bulging parts of the guides. CONSTITUTION:The angle stock 14 emitted from the rolling mill 4 is successively twisted 180 deg. by the twist rollers 5 of the inlet guide 1, the guide rollers 7 of the repeater and the twist rollers 5 of the outlet side guide 3 and is sent into the succeeding rolling mill 12. The coil break of the stretched member in the repeater part of the material 14 is absorbed by the bulging part 10 of the repeater 2 adjacent to the guide 1 and if the stretching increases further, an outside wall 9 is opened when a sensor detects such stretching. The angle stock is satisfactorily rolled even by juxtaposed rolling mills using the repeater.
