無縫鋼管表面產生銹蝕的原因及處理方法

日期:2020-02-06
無縫鋼管表面產生銹蝕的原因及處理方法

無縫鋼管表面有連續凹坑

原因:

1.輥子和凹槽嚴重磨損

2.輥未充分冷卻,表面為粘鋼

3,輸送輥臺表面不光滑

4,廢管在加熱中的高溫加熱時間過長,導致過熱和過熱。

5,上漿用高壓水去除磷是不正常的,氧化鐵皮被清晰,不干凈地壓入無縫鋼管表面

處理方法:更換框架或修理滾筒表面。

無縫鋼管是由鋼錠或實心管坯通過穿孔制成毛細管,然后通過熱軋,冷軋或冷拔制成的。與實心鋼如圓鋼相比,在彎曲和扭轉強度相同的情況下鋼管重量更輕,是一種經濟型截面鋼,廣泛用于制造石油鉆機等結構零件和機械零件桿,汽車傳動軸和自行車。以及鋼結構建筑中使用的腳手架。
