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：1、檢測時，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。</p><p style="text-indent:25px">硬面軋輥：肖氏硬度約為60~85，用于薄板、中板、中型型鋼和小型型鋼軋機的粗軋機及四輥軋機的支撐輥。 ⑷特硬輥：肖氏硬度約為85~100，用于冷軋機。軋機類型：按軋機類型軋輥可分為以下三類： ⑴平面軋輥：即板帶軋機軋輥，其輥身呈圓柱形。一般熱軋鋼板軋機軋輥做成微凹形，受熱膨脹時，可獲得較好的板形；冷軋鋼板軋機軋輥做成微凸形，在軋制時，軋輥產(chǎn)生彎曲，以獲得良好的板形。⑵帶槽軋輥：它用于軋制大、中、小各種型鋼、線材及初軋開坯。在輥面上刻有軋槽使軋件成形。傳統(tǒng)的軋輥選材及其熱處理工藝，同時，對軋輥材料及其熱處理工藝的發(fā)展進(jìn)行了展望。</p><div

style="text-indent:25px">直接接觸軋件的軋輥稱工作軋輥；上海軋輥采購</p><p style="text-indent:25px">粗磨膠輥時可選用粒度為40、46、54號，寬度為30 mm的大氣孔砂輪，磨削總量一般為1 mm，可分三次走刀，進(jìn)刀量分別可為0.4 mm、0.3 mm、0.3 mm，這樣有利于降低膠輥表面溫度。由于粗磨對膠輥表面粗糙度無嚴(yán)格要求，主要是保證膠輥表面圓柱度。粗磨后不應(yīng)立即進(jìn)行精磨，要將并條膠輥放置48 h，使其經(jīng)時效處理后進(jìn)行。精磨膠輥時可選用粒度為60、70、80號，寬度為30 mm的大氣孔砂輪，磨削總量一般為0.5 mm，棉紡企業(yè)一般*需進(jìn)行復(fù)磨而不用粗磨，磨削總量一般為0.3 mm～0.4 mm，可分三次進(jìn)行，進(jìn)刀量分別可為0.2 mm、0.1 mm、0.1 mm，采用小負(fù)荷磨削可使膠輥表面熱量受到控制，磨削粉塵也較少，更有利于砂輪的清潔與鋒利。在砂輪安全線速度的前提下，為保證磨礪質(zhì)量，一般砂輪主軸轉(zhuǎn)速為1800 r/min，相應(yīng)車頭轉(zhuǎn)速約為200 r/min。磨削前需要調(diào)整好磨床尾座，保證磨削后膠輥兩端錐度不大于0.03 mm，磨削行程要設(shè)置為自動走刀以保證磨削速度均勻，之后一次走刀速度要慢，以3 m/min～4 m/min為宜。精磨后膠輥膠層應(yīng)細(xì)膩、光滑，目測其表面無螺旋線，無機械波紋，表面粗糙度Ra值達(dá)到0.4 μm～0.6 μm為好。上海軋輥采購</p><p
