五金套管五金緊固件行業小知識,淬裂原因分析及相對應預防
- 2019-01-17 -

      熱處置是為了讓五金套管失掉更好的功能和強度,但是在熱處置進程中,我們要留意工件發作淬裂的景象。工件一經淬裂就相當于報廢,這樣會形成很大的糜費,因而如何預防淬裂的發作就顯得尤為重要了。     


 緊固件淬裂緣由:    

  1、淬裂和鋼的含碳量有很大的關系,鋼件的含碳量越高,發作淬裂的幾率就越大,為了避免淬裂可選擇0.4%C以下的鋼。   

  2、淬裂和外形也有一定的關系,例如工件存在缺口、尖角、溝槽、孔穴等,這些斷面急劇變化的部位都是淬火內應力集中的中央,所以易發生淬裂。    

  3、溫渡過熱,由于控制溫度不準、溫度的設置過高、爐溫間接加熱部位溫渡過高不平均等要素。    

  4、冷卻,冷卻溫渡過低或冷卻劑的運用不當會形成淬裂,另內在臨界區應該選擇急冷,而在風險區該當慢冷,采取先快后慢的冷卻方式。    


 關于五金套管緊固件淬裂預防措施,自攻螺絲專家次要總結了以下幾點:    

  1. 含碳量0.4%C是淬裂的臨界點,淬火宜選擇低碳鋼。    

  2.淬火鋼應具有優秀的冶金質量和原始組織。    

  3.淬火加熱要留意爐溫平均,防止氧化脫碳等發作。    

  4.淬火冷卻要留意先快后慢的準繩,淬火后要立即回火,避免放置開裂。    

  5.留意工件的外形,其厚度要堅持平均,外形對稱,不要呈現缺口尖角,留意堅持光亮度。
