Title
(EN) PROCESS FOR THE INSERTION AND CONVEYING OF LABILE ADDITIVES IN STREAMS OF MOLTEN MATERIAL
(FR) PROCÉDÉ POUR L'INSERTION ET LE TRANSPORT D'ADDITIFS LABILES DANS DES FLUX DE MATÉRIAU FONDU
Abstract
(EN)
The present invention relates to a process for the insertion and conveying of a labile additive, or a mixture thereof, in a transporting pipe, in which a main stream of molten material flows, said process characterized in that it incorporates said additive, or said mixture, in a portion of the pipe delimited by the main stream, according to one of the following alternative modes: a) in a longitudinal direction with respect to the flow direction of the main stream of molten material, or b) in a transversal direction with respect to the flow direction of the main stream of. molten material, or c) according to a composition of the longitudinal (a) and transversal (b) mode, thus forming a resulting stream which keeps the labile additives segregated from the main stream of molten material.
(FR)
La présente invention concerne un procédé pour l'insertion et de transport, d'un additif labile ou un mélange de celui-ci, dans un tuyau de transport, dans lequel un flux principal de matière en fusion s'écoule, ledit procédé caractérisé en ce qu'il incorpore ledit additif, ou ledit mélange, dans une partie du tuyau délimitée par le flux principal, selon l'un des modes alternatifs suivants : a) dans une direction longitudinale par rapport à la direction d'écoulement du flux principal de matière en fusion, ou b) dans une direction transversale par rapport à la direction d'écoulement du flux principal de matériau fondu, ou c) selon la composition du mode longitudinal (a) et transversalement (b), formant ainsi un flux résultant qui maintient les additifs labile séparé du flux principal de matière en fusion.
