磷铜中间合金是铸造锡磷青铜的主要原材料,同时又是铜的主要脱氧剂,用途很广.我厂每月生产磷铜合金15~20吨,过去采用坩埚熔制,产量低,成本高,质量不稳定,废气不易控制.自74年开始试用铜水包熔制,经过几年试制,日产量由原800公斤提高到1500公斤,质量稳定在含磷量14%左右,同时也解决了废气回收.
Phosphor bronze master alloy is the main raw material for casting tin phosphorus bronze, copper is also the main deoxidizer, a wide range of uses. I plant monthly production of phosphor bronze alloy 15 to 20 tons, the past crucible melting, low yield and high cost , The quality is not stable, exhaust gas is not easy to control.From 74 years trial copper water bag melting, trial after several years, the daily output from the original 800 kg to 1500 kg, the quality is stable at about 14% of phosphorus, but also to solve Exhaust gas recovery.
