1,125,496. Making wire; rolling. SVENSKA METALLVERKEN A.B. 31 Jan., 1967 [1 Feb., 1966], No. 4700/67. Headings B3A and B3M. A number of separate billets are rolled to a predetermined size, are joined end to end, and are then rolled continuously to form a single length of rod or wire, the billets being temporarily held stationary at their adjacent ends during the joining operation. Billets from a furnace 6 or cold billets are individually fed to a continuously driven 3-high mill 1, where they are rolled in several passes to a desired size, and then passed through a reversing shoot 9 to a joining machine 7. The leading end of the billet is joined to the trailing end of a preceding billet which is held in the machine. While the ends are being held and joined, a loop 13 of the preceding billet steadily decreases in size, Fig. 4, while a loop 12 formed by the following billet is allowed by the shoot 9 to increase in size. Intermittently operable feed rollers 11 feed the billets forwardly after each joining step. A continuous finishing mill 14 rolls the joined billets to wire. |
