    優質冷拉方鋼的力學性能及應用舉例
    發布日期:2018-11-17       點擊數:260       
    ? ? ?? 冷拉方鋼指的是在常溫狀態下,采用先進的冷擠壓技術,選擇精確的模具,并以高于鋼筋原本屈服點強度的拉應力,強行拉伸鋼筋,使鋼筋產生塑性變形以達到提高鋼筋屈服點強度和節約鋼材為目的。所拉出的冷拉方鋼成品具有高精度、表面光滑的特征。 關于優質冷拉方鋼的力學性能介紹: 抗拉強度(σb/MPa):315-430; 伸長率(δ5/%):≥33。 結合目前的應用情況來看,冷拉方鋼的應用極其廣泛,主要應用舉例內容如下: 該產品主要可用于制造地腳螺栓、犁鏵、煙筒、屋面板、鉚釘、低碳鋼絲、薄板、焊管、拉桿、吊鉤、支架、焊接結構等。也可用于軋制薄板和盤條。此外還可用于冷、熱軋薄鋼板及以其為原板制成的鍍鋅、鍍錫及塑料復合薄鋼板大量用于屋面板、裝飾板、通用除塵管道、包裝容器、鐵桶、儀表殼、開關箱、防護罩以及火車車廂等。 除了以上的應用之外,目前也有很多優質冷拉方鋼產品可用于盤條,多冷拔成低碳鋼絲或經鍍鋅制成鍍鋅低碳鋼絲,用于捆綁、張拉固定或用作鋼絲網、鉚釘等。關于方鋼理論重量計算公式是邊長乘以邊長Х0.00785=kg/m。其方鋼邊長(mm)、截面面積(cm2)、理論重量 (kg/m)、邊長(mm)、截面面積(cm2)、理論重量(kg/m)。在標準件中,邊長105到250毫米的方鋼未列出截面面積及重量,必要時可參照表列數據的倍數進行算。 優質冷拉方鋼的熱處理工藝知識分享: 在實際加工中,熱處理是一個重要的環節,該產品熱處理規范及金相組織要求為,熱處理采用熱軋工藝。其的金相組織則為鐵素體+珠光體。
