La présente invention se rapporte à des perfectionnements apportés aux blocs de rive (également appelés "dam-block") utilisés pour la coulée continue de barres de cuivre destinées en particulier à la production de fils en cuivre.The present invention relates to improvements made to the edge blocks (also called "dam-blocks") used for the continuous casting of copper bars intended in particular for the production of copper wires.

coulée continue du cuivre. Parmi ces installations, celles appliquant le procédé "CONTIROD" (marque déposée) ont connu un développement considérable. Ce procédé qui est décrit dans 10 "Metallurgie" n° XVI-février 1976 pp comporte l'utili sation d'une lingotière continue Hazelett constituée de deux bandes d'acier sans fin qui forment les parois longitudinales supérieure et inférieure et de deux chaînes de blocs de rives (dam-blocks) formant les parois latérales.continuous copper casting. Among these installations, those applying the "CONTIROD" process (registered trademark) have experienced considerable development. This process which is described in 10 "Metallurgy" n ° XVI-February 1976 pp includes the use of a Hazelett continuous ingot mold made up of two endless steel strips which form the upper and lower longitudinal walls and two chains of blocks of banks (dam-blocks) forming the side walls.
Ces blocs de rives qui sont soumis à des contraintes mécaniques et thermiques très sévères sont réalisés d'une pièce massive en des alliages de cuivre spéciaux ayant subi un traitement de durcissement structural particulier.These banks of banks which are subjected to very severe mechanical and thermal stresses are made in one solid piece from special copper alloys which have undergone a particular structural hardening treatment.
2020
Il s'agit généralement d'alliages cuivre, nickel, silicium, fer et chrome d'une dureté minimale de 200 HV10 (dureté Vickers sous une charge de 10 kg) pour résister à l'écrasement en service et d'une dureté maximale de 220 HV10 pour éviter une fragi-25 lité excessive. De plus, ces alliages doivent être suffisamment conducteurs de la chaleur pour assurer le refroidissement rapide et leur conductibilité thermique, mesurée en terme de conductibilité électrique est d'environ 35 % IACS.They are generally copper, nickel, silicon, iron and chromium alloys with a minimum hardness of 200 HV10 (Vickers hardness under a load of 10 kg) to resist crushing in service and a maximum hardness of 220 HV10 to avoid excessive fragility. In addition, these alloys must be sufficiently conductive of heat to ensure rapid cooling and their thermal conductivity, measured in terms of electrical conductivity is about 35% IACS.
2Q Un alliage convenant pour ces applications est par exemple j une composition connue et brevetée de la formule suivante : ± - 2 - li y | Ni : 1,7 à 2,0 ^2Q An alloy suitable for these applications is for example j a known and patented composition of the following formula: ± - 2 - li y | Ni: 1.7 to 2.0 ^
Si : 0,5 à 0,9 %If: 0.5 to 0.9%
Cr : 0,2 à 0,½ %Cr: 0.2 to 0, ½%
Fe : 0,1 à 0,2 g, 5 qui peut subir un| durcissement structural par précipitation / de Ni^Si.Fe: 0.1 to 0.2 g, 5 which may undergo | structural hardening by precipitation / Ni ^ Si.
i ' Certains alliages cuivre-béryllium peuvent également convenir à cet usage.Some copper-beryllium alloys may also be suitable for this use.
10 *\ Il est cependant apparu que si les compositions d’alliages et " j ~V la conception mime des blocs de rivejfpermet de satisfaire aux j impératifs d’une production continue sans problèmes, les blocs / J de rives subissaient une usure localisée, notamment aux arêtes 15 des blocs. Cette usure pouvait être la cause d’infiltrations de cuivre liquide entre les blocs jointifs formant les parois > latérales de la lingotière mobile, ce qui nécessitait l’arrêt de la production pendant le temps nécessaire à leur remplacement .10 * \ It appeared however that if the alloy compositions and "j ~ V the same design of the blocks of rivejfpermet meet the imperatives of a continuous production without problems, the blocks / J of banks underwent localized wear, in particular at the edges of the blocks 15. This wear could be the cause of infiltration of liquid copper between the contiguous blocks forming the side walls of the mobile ingot mold, which necessitated stopping production for the time necessary for their replacement.
20 * Il apparaîtra à l’homme de l’art que de telles interruptions de production sont particulièrement onéreuses et que la prolongation de la durée de service des blocs de rives constituerait une amélioration considérable apportée à l’exploitation 25 du procédé de coulée continue.20 * It will be apparent to those skilled in the art that such interruptions in production are particularly expensive and that extending the service life of the shoreline blocks would be a considerable improvement in the operation of the continuous casting process.
Tous les efforts pour concilier à la fois les critères de résistance mécanique et de conductibilité thermique suffisantes avec une résistance convenable à l’action du cuivre liquide agissant 30 essentiellement par abrasion se sont avérés négatifs.All efforts to reconcile both the criteria of sufficient mechanical strength and thermal conductivity with a suitable resistance to the action of liquid copper acting essentially by abrasion have been negative.
Le perfectionnement apporté selon l’invention consiste en un bloc de rive destiné à la coulée continue de cuivre du type t f décrit, caractérisé en ce qu’il est constitué d’une masse de è I: I - 3 - forme et de dimensions appropriées à l'installation à laquelle il est destiné, pourvu d'un revêtement d'une dureté supérieure à celle de la masse sous-jacente.The improvement made according to the invention consists of an edge block intended for the continuous casting of copper of the type tf described, characterized in that it consists of a mass of è I: I - 3 - shape and appropriate dimensions for the installation for which it is intended, provided with a coating of a hardness greater than that of the underlying mass.
5 Selon une forme d'exécution particulière de l'invention, la masse du bloc de rive est constituée d'un alliage cuivre-nickel-chrome-silicium-fer.5 According to a particular embodiment of the invention, the mass of the edge block consists of a copper-nickel-chromium-silicon-iron alloy.

Selon une autre forme d'exécution particulière de l'invention, ** I 10 la masse du bloc de cuivre est constituée d'un alliage cuivre-béryllium, i3Î, \According to another particular embodiment of the invention, ** I 10 the mass of the copper block consists of a copper-beryllium alloy, i3Î, \
Ces masses sous-jacentes peuvent recevoir soit un revêtement de chrome pur réalisé par électrolyse, soit un revêtement en 15 acier réfractaire pouvant être déposé par une technique connue en soi, par exemple par projection au chalumeau, brasage ou placage.These underlying masses can receive either a coating of pure chromium produced by electrolysis, or a coating of refractory steel which can be deposited by a technique known per se, for example by spraying with a torch, brazing or plating.
/ Il est totalement inattendu que de tels blocs de rives composites P 20 puissent résister sans (iélaw-inatfiun aux conditions particulières, J ' extrêmement sévères, auxquelles sont exposés les blocs de rives en production./ It is completely unexpected that such P 20 composite shoreline blocks can withstand without (iélaw-inatfiun the particular conditions, J 'extremely severe, to which the shoreline blocks are exposed in production.
Λ /jΛ / d
On n'observe notamment aucune délnminatè.o», éclats ou fissura-/* 25 tions malgré les efforts mécaniques de compression et d'attaque par le cuivre fondu auquel sont soumis les blocs et leur durée de service est considérablement accrue.In particular, no delnminatè.o ", splinters or cracks - / * 25 tions are observed despite the mechanical forces of compression and attack by the molten copper to which the blocks are subjected and their service life is considerably increased.
L'invention sera décrite plus en détail à l'aide des dessins 30 annexés et des exemples qui suivent se rapportant à un bloc de rive destiné à la coulée continue d'une barre de cuivre dans une machine du type Hazelett.The invention will be described in more detail with the aid of the appended drawings and the examples which follow, relating to an edge block intended for the continuous casting of a copper bar in a machine of the Hazelett type.
