冷加工管機(jī)組生產(chǎn)特點(diǎn)是管料從投入到加工成成品通常要經(jīng)過多次冷變形并產(chǎn)生加工硬化，因而整個(gè)生產(chǎn)過程由多個(gè)準(zhǔn)備工序和變形工序組成，且具有往復(fù)循環(huán)的特點(diǎn)，因而工序多，生產(chǎn)周期長(zhǎng)、金屬消耗較大，生產(chǎn)效率較低，一般生產(chǎn)規(guī)模均不大。 </p> <p> 在機(jī)組中同時(shí)配置冷拔和冷軋機(jī)有利于發(fā)揮它們各自的優(yōu)點(diǎn)，特別是對(duì)生產(chǎn)不銹鋼等高合金鋼管和難變形的有色金屬管更為合理和必要。冷拔機(jī)有單根和多根直條拔管機(jī)以及卷筒拔管機(jī)(見卷筒拔管)。單根冷拔時(shí)管材的長(zhǎng)度達(dá)50m，卷筒拔管時(shí)長(zhǎng)達(dá)幾百米。冷拔機(jī)的噸位小為30kN，為7000kN。常規(guī)冷軋管機(jī)有二輥式冷軋管機(jī)和多輥式冷軋管機(jī)兩種。

冷拔加工鋼管正是發(fā)生了加工硬化。冷拔時(shí)金屬發(fā)生塑性變形，晶體內(nèi)部有多個(gè)滑移系啟動(dòng)，位錯(cuò)運(yùn)動(dòng)彼此攔截，許多位錯(cuò)被釘扎住，造成位錯(cuò)塞積，同時(shí)位錯(cuò)源停止動(dòng)作。上述一系列過程導(dǎo)致了位錯(cuò)的可動(dòng)性降低，晶體中的位錯(cuò)密度顯著增加。 </div> <div id="znnxvrh" class="para"> 當(dāng)塑性變形進(jìn)一步發(fā)生，應(yīng)力增加并足以使釘扎的位錯(cuò)開始運(yùn)動(dòng)，螺位錯(cuò)交滑移，刃位錯(cuò)不能交滑移，這樣發(fā)生位錯(cuò)交截，使不動(dòng)階數(shù)增加。 </div> <div id="v199ddt"
