随着我国钢铁工业的迅速发展,我厂生产的制氧机容量也迅速增加。由于机组增加,铜瓦已经淘汰,改用钨金瓦。在增速机密封轴中还用一种铅封瓦。这些轴瓦经过长期运转摩损,需要补焊或全焊修复。我们在技术革命和技术革新中总结了钨金瓦和铅封瓦的施焊工艺,其优点如下: 1、工艺简单,与软钎焊相似,不用浇铸; With the rapid development of China’s steel industry, the capacity of oxygen plant produced by our factory also increased rapidly. As the unit increases, copper has been eliminated, switch to tungsten tile. In the gear shaft seal also used a kind of sealing tile. These bearings undergo long-term wear and tear, repair welding or repair required. We have summed up in the technological revolution and technological innovation tungsten tile and lead tile welding process, the advantages are as follows: 1, the process is simple, and similar to the solder, without casting;
