Embodiment Construction

[0033] exist Figure 1-4A schematic view of a roller guide mechanism 1 according to an embodiment of the invention is shown in . The roll guiding mechanism 1 serves to guide a billet in a longitudinal feed direction A in a rolling mill mainly towards a pair of rolls for shaping the billet. The roller guide mechanism 1 comprises a frame device 2 and a pair of guide rollers 3 , 4 each mounted on an arm 5 , 6 of the frame device 2 . The arms 5, 6 are pivotable and movable so that the lateral distance between the guide rollers 3, 4, ie the distance in a direction perpendicular to the feed direction A, can be adjusted. The guide rollers 3, 4 are rotatable about parallel axes of rotation C3, C4 perpendicular to the longitudinal feed direction A and perpendicular to the transverse direction. The roller guiding mechanism 1 further comprises a control unit 7 comprising positioning means for adjusting the lateral distance between the guide rollers 3, 4 by moving and pivoting the arms ...

Abstract

A roller guide (1) for guiding stock in a longitudinal feeding direction (A) toward a pair of rolls for shaping the stock. The roller guide comprises a frame arrangement (2), a pair of guide rollers (3, 4) configured to, in a closed position, engage opposite surface portions of the stock,and positioning means for adjusting a lateral distance between the guide rollers. The roller guide further comprises detection means (13) configured to detect a longitudinal position of a piece of stock (20) with respect to the guide rollers. The positioning means is configured to adjust the lateral distance between the guide rollers in response to said detection.

Description

technical field [0001] The invention relates to a roller guiding mechanism for guiding a blank in a longitudinal feed direction towards a pair of rollers for forming said blank according to the preamble of claim 1 and a method according to the independent method claim for The method of guiding the blank. In particular, the invention relates to roll guiding mechanisms and methods for use in the production of wire rods, rods and beams. Background technique [0002] Roll guides are generally used to guide hot billets, such as wire billets or bar billets, in rolling mills. Mainly, the roller guide is placed before a pair of rollers used to shape the blank, so it is called an entry roller guide. These roll guides guide the stock to be rolled towards specific rolling grooves. The use of roller guides reduces the risk of damage to the blank when entering between the pair of rollers and enables feeding of the blank at higher feed speeds. [0003] US3935722 discloses a roller gui...
