Abstract

1471596 Joining rails; rolling; welding by pressure LONDON TRANSPORT EXECUTIVE 14 April 1975 [22 April 1974] 17513/74 Headings B3A B3M and B3R A method of profile finishing elongate steel members, such as rails, includes flash-butt welding the members together and hot rolling the weld to the profile of the elongate members by means of loaded rollers and without reheating the weld. The rolling apparatus comprises three pairs of profiled rolls, the end pairs of rolls la, 1b, 3a, 3b, being provided with means 27 for adjusting the gap between the rolls. The centre pair 2a, 2b are mounted in a loading frame comprising vertical tension bars (14), 15, Fig. 4 (not shown), and a cross-bar 16, while the spindle 17 of the roll 2a is additionally located in pressure equalizing links (21), 22, pivotally mounted on spaced vertical supports (23), 24, Fig. 3 (not shown). After the rails have been flash butt welded, excess metal may be stripped from the weld and then the weld is passed through the apparatus while still hot. The rolling load is applied by an hydraulic power cylinder 13 and either the apparatus or the joint may be reciprocated to provide multi-pass rolling.
