The present invention relates to a method for manufacturing plated hollow ingots to be processed further into seamless metal tubes, particularly steel tubes, that are plated on the inside. In order to provide a method with which a hollow ingot that is plated only on the inside can be manufactured and with which the hitherto existing shortcomings are avoided, it is proposed that a hollow cylindrical body formed from the plating material be immersed in a melt of a base material and be removed from the melt following crystallization of a sufficiently thick plating layer, whereby the inner surface of the hollow body is protected during immersion against the access of melt.
Cette invention concerne une méthode de production de lingots creux revêtus à être transformés en tubes métalliques sans soudure, en particulier en tubes d'acier, à paroi intérieure revêtue. Pour obtenir une méthode de production d'un lingot creux dont seule la paroi intérieure est revêtue sans les inconvénients des méthodes courantes, il est proposé de former un corps creux cylindrique à partir du matériau de revêtement, de l'immerger dans le métal de base fondu et de l'en extraire seulement lorsqu'une couche de métal de base suffisamment épaisse s'y soit cristallisée, le corps creux en métal de revêtement étant bouché aux deux extrémités pour empêcher la pénétration de métal de base fondu à l'intérieur.
