                                                                                              鋼管在生產中容易出現裂紋、重皮、夾渣三種質量問題。裂紋產生與離心澆注過程、澆注制度不合理產生;重皮與澆注溫度、澆注轉速有關;夾渣與金屬化學元素含量、扒渣處理有關。

                                                                                              天津無縫鋼管廠家的預防和控制措施有以下:

                                                                                              改進冷軋設備,有效預防裂紋

                                                                                              減少鋼坯在高溫的停留時間,加強孕育特別是隨流孕育效果。隨流孕育劑加入量控制為鋼坯量的0.1-0.25%;確保管模粉分布均勻,控制管模內表面用量為20-30g/m2??刂坪盟浣饘傩碗x心機冶煉工藝參數。

                                                                                              離心機要防止流槽振動造成鋼坯濺出現象,承口砂芯要安放合適,鍍鋅無縫鋼管,避免產生毛刺??刂其撆鞒煞?,降低鋼坯的含硅量,沖入球化劑后W(Si)應控制在0.8-1.2%為宜。離心機機殼內采用均勻布置圓弧形噴淋冷卻管,無縫鋼管廠家,且分段設置,并避免各段的冷卻水相互影響。

                                                                                                   鋼管在生產過程中哪一步都是重要的,都會影響到鋼管的成材率,應該合理正確生產。
