style="text-indent:25px">冷拔方鋼是什么？冷拔方鋼是將經(jīng)熱加工后的鋼材在冷狀態(tài)下進(jìn)行二次加工的一種鋼材，這種鋼材的特點(diǎn)就是更加的精密、尺寸精度高、表面相對(duì)比較光滑，機(jī)械性能好可用于多種機(jī)械行業(yè)的加工之中。它的生產(chǎn)工序是比較多的，這里簡(jiǎn)單介紹一下它的拔制要求：1.拔制方式：長(zhǎng)芯棒拔制；短芯棒拔制；無芯棒拔制；游動(dòng)芯棒拔制。其中多采用短芯棒+無芯棒拔制。2.拔管機(jī)：鏈?zhǔn)?、鋼繩式、液壓式。3.冷拔工具：外模、內(nèi)模、模套、連接桿及螺絲、芯桿、牙板。冷拔鋼種類型號(hào)多嘛？新鄉(xiāng)冷拔六角鋼出廠價(jià)</p><p
