class="khcont">退火在所有的冷軋管生產(chǎn)中是非常重要的工序，退火質(zhì)量的好壞既影響鋼管的性能也影響氧化鐵皮的。冷軋精密鋼管需要配置無氧化光亮退火爐設(shè)備。精密無縫鋼管在硫酸酸洗過程中容易形成以Fe2O3、Fe3O4為主的“黑渣”，在后續(xù)生產(chǎn)中形成表面黑斑。Fe2O3、Fe3O4易溶于鹽酸，為防止黑斑形成則在酸池中加入5-10g/l的NaCl 應(yīng)選用樹脂作潤滑劑，這種潤滑與磷化加潤滑（皂化）相比有明顯的區(qū)別，軋制出來的鋼管呈現(xiàn)鐵基體的本色，既有高的光潔度又有冷軋管般的漂亮外觀色澤。生產(chǎn)冷軋精密無縫鋼管的工業(yè)控制包括模具設(shè)計、退火、酸洗、潤滑等條件控制，同時應(yīng)在毛管質(zhì)量檢測、整修方面做好工作。精軋管技術(shù)包括連軋、精軋管、三輥軋管、CPE頂管、擠壓管等。其中20#精軋管是20世紀90年代才發(fā)展起來的技術(shù)，因其英文名稱為：Accuracy Rolling, 也簡稱為AR軋管。該技術(shù)工藝流程短、操作靈活、鋼種面寬，深受行業(yè)推崇。隨著發(fā)展，該技術(shù)也出現(xiàn)的一定的問題。</div><p><img src="http://2024aiimg.qy55.com//cjjhb_soft/46/80/202402212025026168.jpg"

class="khcont">但是精密鋼管就具備得天獨厚的優(yōu)勢，因為它的表面不易被氧化，這主要和組成精密鋼管的原材料是分不開的。精密不銹鋼管是靠其表面形成的一層極薄而堅固細密的穩(wěn)定的富鉻氧化膜(防護膜)，防止氧原子的繼續(xù)滲入、繼續(xù)氧化，而獲得抗銹蝕的能力。精密鋼管的表明渡化膜中耐腐蝕性比較弱的部分會因為自激反應(yīng)形成點腐蝕反應(yīng)，生產(chǎn)小小的孔，會和接近的氯離子容成很強的腐蝕性的溶液，加快腐蝕的速度。再加上不銹鋼內(nèi)部的晶間腐蝕開裂，都會對不銹鋼板的表面的渡化膜進行破壞。因此，對精密鋼管的表層要進行一定層次的清潔保養(yǎng)，來更好的延長精密鋼管的使用壽命。精密鋼管之所以有這個稱謂是因為精密鋼管在尺寸上更加，鋼管的內(nèi)外表面也更加光滑，韌性也更好。鋼管擴口、壓扁無裂痕、冷彎不變形，并能承受高壓，能作各種復(fù)雜變形及機械深加工處理。</div><p><img
