style="text-indent:25px">不銹鋼無縫管加熱工藝的制定應綜合考慮熱爐設備、管坯或鋼管種類、數量等固有屬性，嚴格控制加熱速度、保溫時間和冷卻速度，避免產生裂紋、過熱或過燒。以穿孔階段管坯加熱為例，考慮不銹鋼常溫下導熱系數小(即傳熱慢)，而膨脹系數大，所以應當在爐內應有較長的預熱時間，加熱初期的升溫速度宜慢，以防產生熱裂紋；當坯溫超過一定溫度(一般850℃左右)后，不銹鋼的導熱性和塑性迅速增加，同時不銹鋼在高溫段停留的時間太長會產生α相，即生成鐵素體，α相超過一定比例后，金屬熱塑性急劇下降，嚴重時，將導致穿孔無法進行，而且高溫及長時保溫還會使內部晶粒粗大，因此在均熱階段則應當快速加熱，短時間完成均熱。山西工業(yè)無縫不銹鋼管廠家</p></p><br
