CA 2334851

The invention relates to a method for producing metal shapes with a partially or totally polygonal cross-section by means of continuous casting in a double-flanged wheel and continuous rolling using a series of at least 3 pairs of rollers with a peripheral flange, whereby said rollers are alternately horizontally and vertically disposed in a symmetrical position with respect to said shape. The inventive method is characterised in that the flanges of the first pairs of rollers are identical to those used to produce shapes with a circular cross-section; the last pair of rollers has flanges defining a section that corresponds substantially to that of the desired shape; the section formed by the grooves of the last pair of rollers has curve radiuses of between 1 and 5 mm at the highest points of the polygon; the sides of the polygon that are not parallel to the air gap pertaining to the last pair of rollers have a clearance angle of ? - 3· in comparison with the corresponding sides of the section of the final shape. The invention can be used to produce copper or aluminum alloy shapes for drawing or and/or subsequent redrawing.

L'invention concerne un procédé de fabrication de profilés métalliques de section partiellement ou totalement polygonale par coulée continue dans une roue à gorge et laminage en continu à l'aide d'une série d'au moins 3 paires de galets munis d'une gorge périphérique, et disposés symétriquement par rapport au profilé, et alternativement horizontaux et verticaux. Ce procédé est caractérisé en ce que: les gorges des premières paires de galets sont identiques à celles des galets utilisés pour la fabrication de profilés de section circulaire; la dernière paire de galets comporte des gorges délimitant une section correspondant sensiblement à celle du profilé désiré; la section formée par les gorges de la dernière paire de galets présente aux sommets du polygone des rayons de courbure compris entre 1 et 5 mm; les côtés du polygone non parallèles à l'entrefer de la dernière paire de galets présentent, par rapport aux côtés correspondants de la section du profilé final une dépouille comprise entre 1/2 et 3~. L'invention s'applique notamment à la fabrication de profilés en alliage d'aluminium ou de cuivre destinés à un tréfilage et/ou un étirage ultérieur.
