我厂每年须要大量磷铜中间合金,用于熔炼各种铜合金的脱氧及配制磷青铜合金用.长期以来我们都自行配制.曾采用过磷蒸气加入法和压入法等,这些方法有很多缺点:熔制时间长,磷的损耗大,回收率低,熔制时难于控制,制造成本高等.这些方法很久就已经不采用了,而采用本刊1955年第7期所介绍的磷铜中间合金的快速熔制法.按照此法配制磷铜中间合金,含磷量都
Our factory needs a large amount of phosphor bronze master alloy every year, which is used for smelting all kinds of copper alloy deoxidation and preparation of phosphor bronze alloy .We have long-term self-formulated .Polyphosphoric vapor addition method and press-in method, there are many Disadvantages: long melting time, large loss of phosphorus, low recovery, difficult to control when melting, high manufacturing costs, etc. These methods have not been adopted for a long time, and the use of our magazine No. 7 in 1955 described in the middle of phosphor bronze Rapid melting of the alloy method. In accordance with this method preparation phosphor bronze master alloy, phosphorus content
