Abstract
(EN)
Provided are a reinforced steel wire for a rubber hose, and a production process thereof, comprising the steps: wire rod preprocessing; pressure-die rough drawing on a direct-feed wire drawing machine; cyanide-free electroplating of copper; using a pressure dual-die to fine-draw the copper plated steel wire on the direct-feed wire drawing machine; cleaning the drawn wire to remove the residual soap powder on the surface to obtain a finished steel wire; obtaining a reinforced steel wire fabricated according to the described production process. The reinforced steel wire for a rubber hose and production process thereof achieve production of large-specification rubber-hose steel wire, and can satisfy various steel-wire performance requirements; the production process eliminates the need for the process steps of intermediate heat treatment and water tank drawing and greatly reduces production costs, while also significantly increasing production efficiency; the quality and overall performance of steel wires are significantly improved, and can be adapted to the production of steel wire of various strengths.

L'invention concerne un fil d'acier renforcé destiné à un tuyau en caoutchouc et un procédé de production associé, comprenant les étapes suivantes : prétraitement de tige de fil ; étirage grossier par matrice de pression sur une machine d'étirage de fil à alimentation directe ; électrodéposition de cuivre sans cyanure ; utilisation d'une matrice double de pression pour étirer finement le fil d'acier plaqué de cuivre sur la machine d'étirage de fil à alimentation directe ; nettoyage du fil étiré pour éliminer la poudre résiduelle de savon de la surface pour obtenir un fil d'acier fini ; et obtention d'un fil d'acier renforcé, fabriqué selon le procédé décrit de production. Le fil d'acier renforcé destiné à un tuyau en caoutchouc et le procédé de production associé permettent la production d'un fil d'acier de tuyau en caoutchouc de grande qualité et peuvent répondre à diverses exigences en matière de performances de fils d'acier ; le procédé de production supprime le besoin d'étapes de procédé de traitement thermique intermédiaire et d'étirage à réservoir d'eau et réduit considérablement les coûts de production, tout en augmentant également nettement le rendement de production ; la qualité et les performances globales des fils d'acier sont nettement améliorées et peuvent être adaptées à la production de fil d'acier de diverses résistances.
