style="text-indent:25px">冷拔圓鋼精度高，機(jī)械性能高，不經(jīng)加工就可以使用，在金屬加工制造業(yè)中比較受歡迎的鋼材。它與另一種常見(jiàn)的鋼材冷軋圓鋼在處理工藝有什么不同呢？冷拔圓鋼是將光圓鋼筋通過(guò)硬質(zhì)合金拔絲模孔強(qiáng)行拉拔。冷拔作用比純拉伸的作用強(qiáng)烈，鋼筋不僅受拉，而且同時(shí)受到擠壓作用。經(jīng)過(guò)一次或多次的冷拔后得到的冷拔低碳鋼絲，其屈服點(diǎn)可提高40%~60%，但失去軟鋼的塑性和韌性，而具有硬鋼的特點(diǎn)。冷軋，是將圓鋼在冷軋機(jī)上軋成斷面形狀規(guī)則的鋼筋，可提高其強(qiáng)度及與混凝土的粘接力。鋼筋在冷軋時(shí)，縱向與橫向同時(shí)產(chǎn)生變形，因而能較好地保持其塑性和內(nèi)部結(jié)構(gòu)均勻性。河南冷拔方鋼非標(biāo)定做</p></p><br
