style="text-indent:25px">軋輥車間主要依靠磨床渦流探傷設(shè)備、操作人員觀察和軋輥管理人員使用磁粉探傷或超聲波探傷儀器來監(jiān)測軋輥存在的裂紋?，F(xiàn)在一般都采用自動渦流探傷與手動超聲波檢測結(jié)合進(jìn)行，更加降低了軋輥缺陷影響的幾率。為磨削出合格的軋輥提供了保障。常見的探傷方法　　常見軋輥探傷方法軋輥的探傷方法主要有以下幾種：磁粉探傷、滲透著色探傷、渦流探傷、超聲波探傷。下面逐一進(jìn)行介紹。1、磁粉探傷　　磁粉探傷技術(shù)主要被用來測定軋輥輥身表面的裂紋和在輥頸區(qū)域的疲勞裂紋、過度的周期負(fù)荷或隨后產(chǎn)生的正常腐蝕。</p><p style="text-indent:25px">由于軋輥超聲波有測量盲區(qū)的固有特性，因此，如果近距離測量時(shí)，當(dāng)測量位置發(fā)生變化而接收到的數(shù)據(jù)不變時(shí)，說明進(jìn)入了測量盲區(qū)。3、超聲波在測量遠(yuǎn)處物體時(shí)，如果沒有測量數(shù)據(jù)返回，可能是超出測量范圍，或是測量角度不對?？梢赃m當(dāng)調(diào)整測量角度。合理的軋輥探傷工藝的優(yōu)點(diǎn)1.節(jié)約成本。（1）未使用軋輥探傷的軋鋼廠在修磨軋輥時(shí)一般采用開環(huán)磨削或車削的方式操作，一般說來這意味著要去掉軋輥表面的一個標(biāo)準(zhǔn)深度，如果缺陷較小，造成了不必要的浪費(fèi)；如果缺陷較大，可能去除不干凈。軋輥在熱處理過程中，對軋輥鋼的淬火和加熱限制在奧氏體中含碳量不超過0.6%的程度。</p><div

style="text-indent:25px">為了減少軋輥工藝重淬消耗，提高軋輥的淬硬層深度、接觸疲勞強(qiáng)度、韌性，延長其使用壽命，從20世紀(jì)70年代后期到80年代中期，國內(nèi)外開始研究使用鉻含量在3%～5%的深淬硬層冷軋工作輥鋼。3%鉻冷軋輥不需重淬，且有效淬硬層深度可達(dá)到25～30mm，5%Cr冷軋輥有效淬硬層深度則達(dá)到40mm，其耐磨性和抗事故性能也有明顯提高。在這一階段，國內(nèi)試制了9Cr3MoV鋼，國外一些制造廠也先后開發(fā)推廣了深淬硬層冷軋輥，如美國的3.25%Cr鋼和5%Cr鋼，日本的ＫａｎｔｏｃＲＰ53、ＦＨ13、ＭｎＭＣ3和ＭＣ5等。這些鋼都采用高碳高合金材料，具有良好的硬度和耐磨性，但軋輥淬硬表面脆性大，接觸疲勞壽命低，質(zhì)量不穩(wěn)定。軋輥是使（軋材）金屬產(chǎn)生塑性變形的工具。上海軋輥批發(fā)價(jià)格</p><p

style="text-indent:25px">使用軋輥探測裝置后，能確保比較小的去除量，正常情況下只為原來的l/3～1/2，避免了不必要的損失，又確保了軋輥的磨削質(zhì)量。（2）可以減少軋機(jī)停機(jī)時(shí)間，增加軋輥使用壽命、減少廢鋼量以及由于在正常操作情況下，裂紋擴(kuò)展導(dǎo)致的產(chǎn)品質(zhì)量下降情況。應(yīng)用合理的軋輥探傷后基本能保證每根軋輥都用到保證的比較小尺寸才報(bào)廢。這樣就可以解決以前很多軋輥由于存在內(nèi)部缺陷檢查不出來，造成缺陷擴(kuò)展，比較后發(fā)生許多斷輥或其它嚴(yán)重影響生產(chǎn)的事故。2.改進(jìn)質(zhì)量使用了軋輥探傷裝置意味著可以將軋輥上的缺陷去除干凈，同時(shí)保證了軋輥機(jī)械性能的完整性和表面的光潔度。這樣就能夠保證不因這些原因使產(chǎn)品的質(zhì)量降低。上海軋輥一般多少錢</p></p><br
