1、使不銹鋼無(wú)縫管安排和成分均勻一致,這對(duì)質(zhì)料特別主要,因?yàn)闊彳埞懿母鞫蔚能堉茰囟群屠鋮s速度不一樣,形成安排結(jié)構(gòu)不一致。在高溫下原子活動(dòng)加重,σ相溶解,化學(xué)成分趨于均勻,疾速冷卻后就取得均勻的單相安排。 </p> <p> <br /> </p> <p> 2、消除加工硬化,以利于持續(xù)冷加工。通過(guò)固溶處理,歪扭的晶格康復(fù),伸長(zhǎng)和破碎的晶粒從頭結(jié)晶,內(nèi)應(yīng)力消除,鋼絲抗拉強(qiáng)度降低,伸長(zhǎng)率上升。 </p> <p> <br /> </p> <p>
