JPS56102302A - Manufacture of long sized metallic shape - Google Patents

Abstract

PURPOSE: To prevent the product from being injured, and to continuously manufacture a good composite shape, by first rolling the metallic materials together with an accompanying dummy tape, and by allowing to make the dummy tape contact with the peeling jig for preventing the clad metallic shape from allowing directly to contact with the peeling jig.

CONSTITUTION: An aluminum material 5 and a stainless steel material 6 sre respectively supplied from the feeders 1, 2, and are applied a chemical and a mechanical preptreatments by the pretreators 3, 4. Then, the materials 5, 6 are heated respectively by heaters 7, 8 are guided by the cladding guide 11, and are fed to the rolling rolls 12, 13. On the other hand, a dummy metallic tape 10 is supplied from the feeder 9, and joins the clad materials 5, 6 at the cladding guide 11, and the confluent three materials 5, 6, 10 are fed to the rolling rolls 12, 13 which then applies them a hot rolling work under a 40W80% draft percentage to these materials 5, 6 10. The metallic tape 10 is located between the clad materials 5, 6 and the surface of the grooved lower roll 13, and contacts with the peeling jig 17; hereby, the clad material is protected from being injured by the peeling jig 17. The metallic tape 10 passes over the roll surface and is peeled off of the clad material 16, and is coiled by the coiling reel 15. On the other hand, the clad material 16 is coiled by the coiler 14.
