焊管的熱處理有哪些工藝發布者:admin  點擊:770焊管加工過程中有很多工序,每一個細節都是我們需要注意的,焊管在應用之前是需要經過各個流程的加工的,焊接鋼管的熱處理是焊接鋼管加工中很重要的一個環節。熱加工首先是將金屬材料放在一定的介質內加熱、保溫、冷卻,通過改變材料表面或內部的金相組織結構,來控制其金屬性能的一種金屬熱加工工藝。 結構焊管工件在加熱和冷卻過程中,由于表層和心部的冷卻速度和時間的不一致,形成溫差,會導致體積膨脹和收縮不均而產生應力,即熱應力。在熱應力的作用下,由于表層開始溫度低于心部,收縮也大于心部而使心部受拉,當冷卻結束時,由于心部冷卻體積收縮不能自由進行而使表層受壓心部受拉。即在熱應力的作用下使工件表層受壓而心部受拉。 這種現象受到冷卻速度,材料成分和熱處理工藝等因素的影響。 當冷卻速度愈快,含碳量和合金成分愈高,冷卻過程中在熱應力作用下產生的不均勻塑性變形愈大,形成的殘余應力愈大。
