真空熔炼是改善康铜合金细丝加工性能的有效方法。本文介绍了真空熔炼过程中,各元素含量的相对变化;合金的化学成分均匀性;采用不同熔炼工艺生产的康铜合金,拉制细丝时的加工性能对比以及制成细丝时的各项性能指标。认为真空熔炼的康铜合金,化学成分均匀、比电渣重熔以及其它非真空熔炼的康铜合金加工性能好,成材率高。采用真空熔炼的康铜合金,能稳定地生产出如.时mm细丝。本文还探讨了成品减面率、热处理工艺对康铜合金细丝性能的影响。认为减面率对成品细丝占(延伸率)和。。(抗张强度)无显著影响,成品热处理制度是影响合金细丝性能的主要因素。主张采用真空熔炼的康铜合金,大的冷加工减面率,高温快速连续退火的工艺生产康铜合金细丝。推荐按如.0关“3·o苦”1·尹“。·3芳”0.02井mm工艺生产和.肥mm合金细丝
Vacuum smelting is an effective method to improve the processing performance of ACTON filament. This article describes the relative changes in the content of elements in the vacuum melting process, the chemical composition of the alloy uniformity, the use of different smelting process production of copper alloy, draw the filaments of the processing performance comparison and when the filament Performance. It is believed that the vacuum melting of copper alloy, chemical composition, electroslag remelting and other non-vacuum melting of Hong Tong copper alloy processing performance, high yield. The use of vacuum melting of copper alloy, can produce stable, such as when mm filament. The article also discusses the finished product reduction rate, heat treatment process on the performance of the constant copper alloy filament. Think of the reduction rate of finished filaments as (elongation) and. . (Tensile strength) had no significant effect, finished heat treatment system is the main factor affecting the performance of alloy filaments. Advocated the use of vacuum melting of Hong Tong copper alloy, a large cold reduction rate, high temperature rapid continuous annealing process Kang Tong alloy filament.
