style="text-indent:25px">軋輥渦流檢測原理：渦流檢測是建立在電磁感應(yīng)原理基礎(chǔ)之上的一種無損檢測方法，它適用于導(dǎo)電材料。當(dāng)把一塊導(dǎo)體置于交變磁場之中，在導(dǎo)體中就有感應(yīng)電流存在，即產(chǎn)生渦流。由于導(dǎo)體自身各種因素（如電導(dǎo)率、磁導(dǎo)率、形狀，尺寸和缺陷等）的變化，會導(dǎo)致渦流的變化，利用這種現(xiàn)象判定導(dǎo)體性質(zhì)，狀態(tài)的檢測方法，叫渦流檢測。渦流探傷的優(yōu)點(diǎn)：1、檢測時(shí)，線圈不需要接觸工件，也無需耦合介質(zhì)，所以檢測速度快。2、對工件表面或近表面的缺陷，有很高的檢出靈敏度，且在一定的范圍內(nèi)具有良好的線性指示，可用作質(zhì)量管理與控制。3、能測量金屬覆蓋層或非金屬涂層的厚度。軋輥能感生渦流的非金屬材料其主要優(yōu)點(diǎn)是能探測次表面缺陷以及能探測復(fù)合澆注軋輥的結(jié)合處的缺陷。上海軋輥哪家強(qiáng)</p><p

style="text-indent:25px">軋輥的構(gòu)造：(1)輥身:軋輥與軋件接觸并使金屬產(chǎn)生塑性變形的部分。(2)輥頸:軋輥支撐部分，安裝在軸承里置于機(jī)架中，并通過軸承座和壓下裝置把軋制力傳給機(jī)架。(3)輥頭:通過與聯(lián)軸器相連接來傳遞軋件扭矩的。軋輥常用的材料有55Mn2、55Cr、60CrMnMo、60SiMnMo等，熱軋輥使用在開坯，厚板，型鋼等加工中，它承受了強(qiáng)大的軋制力，劇烈的磨損和熱疲勞影響，而且熱軋輥在高溫下工作，并且允許單位工作量內(nèi)的直徑磨損，所以不要求表面硬度，只要求具有較高的強(qiáng)度，韌性和耐熱性。熱軋輥只采用整體正火或淬火，表面硬度要求HB190~270硬度。上海軋輥哪家強(qiáng)</p></p><br
