Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania drutów bimetalowych poprzez umieszczenie w stalowej rurce 316L stanowiącej płaszcz rdzenia z Ag i wieloetapowym ciągnieniu, który charakteryzuje się tym, że po pierwszym ciągnieniu zaciskającym prowadzi się międzyoperacyjną obróbkę cieplną w temperaturze 900°C - 940°C przy ciśnieniu 990 - 1100 bar, a następnie po każdorazowym kolejnym ciągnieniu ze średnim gniotem sumarycznym 30% - 35% prowadzi się przesycanie w temperaturze 900°C - 930°C w czasie 1 - 1.5 h, aż do uzyskania pożądanej średnicy.The subject of the application is a method of manufacturing bimetallic wires by placing an Ag core in a 316L steel tube constituting a casing and multi-stage drawing, which is characterized in that after the first compressive drawing, an intermediate heat treatment is carried out at a temperature of 900°C - 940°C at a pressure of 990 - 1100 bar, and then after each subsequent drawing with an average total reduction of 30% - 35%, solution heat treatment is carried out at a temperature of 900°C - 930°C for 1 - 1.5 h, until the desired diameter is obtained.
