Procédé pour fabriquer une matière composite métallique en forme de bande par enrobage par plongée à haute température d'une bande de support métallique, sur la surface de laquelle, lorsque la bande de support est guidée à travers une matière de revêtement métallique fondue ayant une température plus élevée que celle de la matière de support, une mince couche de cette matière de revêtement différente de la matière de la bande de support est cristallisée par solidification, la bande de support, avant d'être guidée à travers la matière de revêtement fondue, étant préchauffée sur sa surface et prétraitée par addition ou insertion d'éléments chimiques, grâce auxquels, pendant le guidage à travers la matière de revêtement fondue, entre la surface prétraitée de la bande de support et la coque se cristallisant sur la surface de la bande de support, il se crée, par des processus de diffusion, une zone de liaison en une matière à gradient, dont la température du liquidus, au moins dans des parties de cette zone de liaison, se trouve au-dessous de la température du liquidus de la matière de la bande de support et de la matière de revêtement et, de plus, dans cette zone, il se crée des portions en phase liquide.
  2. Procédé selon la revendication 1,
    caractérisé en ce que la bande de support, pour prétraiter sa surface, est guidée à travers un agent qui contient les éléments chimiques correspondants pénétrant au moins partiellement dans la surface.
  3. Procédé selon la revendication 2,
    caractérisé en ce que l'agent est un gaz, comme de l'azote, de l'hydrogène, du monoxyde de carbone, de l'ammoniac ou du dioxyde de carbone.
  4. Procédé selon la revendication 2,
    caractérisé en ce que l'agent est un liquide comme de l'acide sulfurique, de l'ammoniaque liquide ou de l'azote liquide.
  5. Procédé selon la revendication 2,
    caractérisé en ce que l'agent est une matière solide, comme un sel de cyanure, un carbonate ou un ferrocyanure de potassium.
  6. Procédé selon la revendication 1,
    caractérisé en ce que la bande de support est constituée d'acier qui présente, dans la zone de sa surface, une teneur en carbone > 20 ppm.
  7. Procédé selon la revendication 1,
    caractérisé en ce que la bande de support est constituée d'acier qui, dans la zone de sa surface, présente une teneur en azote > 20 ppm.
  8. Procédé selon une des revendications 2 - 5,
    caractérisé en ce que la vitesse de transport de la bande de support et/ou sa profondeur de plongée dans la matière de revêtement liquide sont réglées de manière qu'un temps de plongée minimal de 50 ms est obtenu.
  9. Procédé selon au moins une des revendications précitées,
    caractérisé en ce que la surface de la bande de support est rendue rugueuse avant la plongée dans la matière de revêtement liquide.
  10. Procédé selon au moins une des revendications précitées,
    caractérisé en ce que la bande de support est un acier contenant du carbone qui est préchauffé, au moins sur sa surface, à une température de Tvor > 900°C.
  11. Procédé selon au moins une des revendications précitées,
    caractérisé en ce que la matière de revêtement est un acier fortement allié, en particulier un acier allié au chrome.
  12. Dispositif pour fabriquer une matière composite métallique en forme de bande par enrobage par plongée à haute température d'une bande de support métallique (21) selon le procédé décrit dans les revendications 1 à 11, comportant un récipient métallurgique (11) pour recevoir la matière de revêtement liquide à travers laquelle la bande de support peut être guidée dans une direction de traversée avantageusement verticale au moyen de paires de rouleaux agencées du côté d'entrée et du côté de sortie, ainsi qu'un dispositif de préchauffage (41) disposé en amont du récipient métallurgique pour la bande de support (21), qui est agencé dans un carter (61) entourant la bande de support (21) et agencé dans la zone d'entrée avant le récipient métallurgique (11), dans lequel l'agent provenant d'une alimentation (52) peut être introduit par l'intermédiaire d'au moins un conduit d'amenée (51) guidé dans le carter,
    caractérisé en ce que des éléments de mesure (91, 92, 93) pour détecter la température du bain de fusion, la température de la bande de support (21), ainsi que la vitesse sont prévus, qui commandent, par l'intermédiaire d'un processeur (94), au moins un actionneur (95) pour régler la vitesse de la bande de support (21) et, soit sur le conduit d'amenée pour souffler un agent gazeux dans l'espace interne (62) du carter (61) et/ou sur la surface de la bande de support, des buses de soufflage (53) ou, pour pulvériser un agent liquide (51) sur la surface de la bande de support (21), des buses de pulvérisation (55) sont prévues, ou en ce que, par l'intermédiaire du conduit d'amenée (51, 59), des matières solides susceptibles de ruisseler peuvent être amenées dans des goulottes (57), les matières solides pouvant être amenées en contact avec la surface de la bande de support (21), ou en ce que, de façon alternative, l'agent, comme matière solide pouvant être chargée ensuite (B), peut être pressé contre la surface de la bande de support (21).
