Abstract
1355144 Making rolled metal sections; breaking BRITISH STEEL CORP 16 Feb 1973 [18 Feb 1972] 7680/72 Headings B3A B3E and B3M A method of making rolled metal sections 20, 21 comprises hot rolling the metal to form a length of uniform cross-section in which two parallel webs 36, 38, each constituting part of a finished rolled section are offset and joined by a relatively thin bridge 12, allowing the rolled length to cool to a substantially non-plastic condition and separating the sections 20, 21 by rotating one finished section with respect to the other about the bridge 12 to fracture the bridge. The sections 20, 21 are of modified T-section for use as a light shaft guide rail. The cross-piece 14 of each section is formed flat by rolling on a universal mill, Fig. 1 (not shown). The rolled length is fed into separating apparatus and is secured therein by hinged latches 33 and inner plates 32 of clamps 24, 25. A pin 29 on the clamp 25 moves in an arcuate slot 30 formed in the clamp 24, the centre of curvature of the slot being located on the bridge 12. A pneumatic cylinder 28 pivots the clamp 25 about an axis passing through the bridge 12 to fracture it. If necessary the cylinder is repeatedly actuated. The rolled metal sections may be of tee or angle section or of other cross-sectional forms.
