我厂柴油机連杆和曲軸的軸瓦,都是在銅瓦內澆鑄一层錫基巴氏合金。过去在加工軸瓦內孔时,把車下来的合金末子和銅末子一起倒掉,这是很大的浪費。为了节約金屬材料,我們把这些混有銅末子的合金末子存放起来,有了一定数量以后,回收一次。回收时把它放在坩堝中加热,用氯化銨作熔剂,由于銅和巴氏合金熔点不一样,就利用这个道理来回收巴氏合金。巴氏合金 I plant diesel engine connecting rod and crankshaft bearing, are cast in a layer of copper-tin Babbitt alloy. In the past in the process of processing bushing bore, the car down the alloy with the end of the coin and copper drained together, which is a great waste. In order to save metal materials, we put these alloy powder mixed with copper terminal deposit stored, with a certain amount, recycling time. Recycling put it in the crucible for heating, with ammonium chloride as a flux, due to the melting point of copper and Babbitt are not the same, we use this truth to recover the Babbitt. Babbitt
