Description
<EMI ID=1.1> L'invention se rapporte au domaine de la métallurgie. Les objectifs pour lesquels l'application de l'invention est possible et avantageuse sont des procédés pour la déformation à froid de matériaux métalliques, par exemple pour le tréfîlage de même que pour l'étirage de fil, profilés, tubes et tôles, en particulier pour l'étirage avec lubrification .hydrodynamique. Pour l'étirage de matériaux métalliques on utilise des agents de lubrification solides, semi-solides ou liquides. Comme lubrifiants liquides on connait entre autres des stéa- <EMI ID=2.1> <EMI ID=3.1> ple que le stéarate de sodium n'est utilisable que pour une <EMI ID=4.1> opératoire continu pour une déformation en plusieurs' stades <EMI ID=5.1> solvant contenu dans le lubrifiant qui a un point d'ébulli- <EMI ID=6.1> exécuté de manière très soignée parce que la viscosité dynamique du lubrifiant en cas de séchage insuffisant est encore plus faible. Au surplus un désavantage est que ce lubrifiant <EMI ID=7.1> taines circonstances, un prétraitement dégraissant supplémentaire de l'article à étirer devient nécessaire. l'objectif de l'invention réside dans l'élargissement du domaine d'application des lubrifiants solides et semi- solides et dans l'abaissement de la dépense technologique dans la déformation à froid des matériaux métalliques. l'invention s'impose pour tâche de développer un procédé dans lequel est réalisée une couche de lubrifiant homogène à haute viscosité dynamique, comme celle qui est nécessaire dans la déformation à froid de matériaux à plus haute résistance. Cet objectif est atteint avec un procédé dans lequel, sur le matériau à déformer ou sur les surfaces d'outil, est appliqué un lubrifiant dans lequel sont contenus dans un solvant organique ayant un point d'ébullition égal ou infé- <EMI ID=8.1> <EMI ID=9.1> <EMI ID=10.1> <EMI ID=11.1> <EMI ID=12.1> composés organiques chlorés ou fluorée, - comme par exemple de la trifluoracétone. Comme composant de mélange solvant ayant <EMI ID=13.1> ployer ici du benzol et/ou du trichloréthylène. , L'invention prévoit, en outre - que le lubrifiant puisas <EMI ID=14.1> amphotères ou non ioniques. Dans ce cas les films résiduels de lubrifiant éventuels se laissent enlever simplement et facilement avec de l'eau, laquelle peut aussi être chauffée. <EMI ID=15.1> <EMI ID=16.1> <EMI ID=17.1> manière homogène le lubrifiant à l'état liquide sur-la sur- face de l'article à étirer et il reste adhérent, après éli- mination du solvant, sous forme d'une couche de lubrifiant solide sur l'article à étirer, en pouvant en règle générale renoncer à un prétraitement de l'article à étirer avec des supports de lubrifiants. Le lubrifiant combine les avantages des lubrifiants solides qui, en raison de leur viscosité dynamique élevée à l'étirage, peuvent s'employer aussi pour l'étirage de matériaux à plus haute résistance et qui sont fabricables avec une dépense relativement faible, avec les avantages des lubrifiants liquides ou semi-solides qui assurent une application homogène du lubrifiant. Le lubrifiant est utilisable dans le procédé d'étirage continu en plusieurs stades. La couche homogène de lubrifiant sur l'article à étirer garantit des conditions d'étirage stables et .les avan- <EMI ID=18.1> <EMI ID=19.1> <EMI ID=20.1> <EMI ID=21.1> <EMI ID=22.1> <EMI ID=23.1> nullement de problèmes de protection de l'environnement ou <EMI ID=24.1> des gaz aspirés. Exemple . Une forme avantageuse de réalisation de l'invention <EMI ID=25.1> riau à déformer un lubrifiant qui contient du benzol comme solvant organique. Dans ce solvant est dissous du stéarate de <EMI ID=26.1> brifiant convient particulièrement pour l'étirage hydrodynamique, par exemple du fil d'acier à ressort. On a pu ainsi déformer avec le lubrifiant un fil d'acier à ressort ayant un. diamètre initial.de 10 mm et une résistance initiale de 1600 <EMI ID=27.1> filière d'étirage l'article d'étirage possède une qualité de surface remarquable et montre une couche homogène de lubrifiant solide résiduel sur sa surface. Exemple 2 <EMI ID=28.1> de calcium. Dans ce liquide contenant du stéarate de calcium <EMI ID=29.1> étirer. Lors de l'étirage on obtient, en raison des propriétés de viscosité dynamiques excellentes du lubrifiant; des <EMI ID=30.1> <EMI ID=31.1> <EMI ID=32.1> lubrifiant à viscosité dynamique élevée qui, avant comme <EMI ID=33.1> <EMI ID=34.1> <EMI ID=35.1> REVENDICATIONS <EMI ID=36.1> 1.- Procédé de déformation à froid de matériaux métalli- <EMI ID=37.1> <EMI ID=38.1> dans un solvant organique ayant un point d'ébullition égal ou inférieur à 200[deg.]0, sont contenus des sels alcalins, alcalino-terreux, ammoniques et de zinc ou de métaux ou nonmétaux apparentés d'acides ayant plus de 10 atomes de carbone dans la molécule, de préférence d'acides ayant 15 à 20 atomes de carbone dans la molécule.
