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(duì)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(shí)效處理后進(jìn)行。精磨膠輥時(shí)可選用粒度為60、70、80號(hào)，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(dòng)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(cè)其表面無螺旋線，無機(jī)械波紋，表面粗糙度Ra值達(dá)到0.4 μm～0.6

style="text-indent:25px">冷軋工作輥的熱處理一般有鍛后熱處理，調(diào)質(zhì)和表面淬火。鍛后熱處理鍛后熱處理的目的是降低硬度，消除殘余應(yīng)力，同時(shí)還改善組織，得到細(xì)粒珠光體，消除網(wǎng)狀碳化物。鍛后熱處理還有擴(kuò)氫作用。擴(kuò)氫時(shí)間視鋼錠氫含量而定，一般認(rèn)為[H]≤2×10-4%時(shí)，可取消擴(kuò)氫處理。調(diào)質(zhì)：調(diào)質(zhì)的目的是為表面淬火提供組織準(zhǔn)備，使輥頸和輥心得到強(qiáng)韌性配合良好的粒狀珠光體組織，獲得良好的綜合力學(xué)性能，以承受激烈的表面淬火。表面淬火：表面淬火使工作輥獲得高硬化層。</p><p

style="text-indent:25px">實(shí)際的軋輥生產(chǎn)表明，高鉻鑄鐵軋輥有較好的抗熱裂性能，原因是軋輥表面生成一層致密且有韌性的鉻的氧化膜，能減少熱裂紋的數(shù)量和深度。因此，高鉻鑄鐵輥在20世紀(jì)80年代被非常普遍用于精軋前架。目前，高鉻鑄鐵復(fù)合軋輥已普遍用作熱軋帶 (鋼)連軋機(jī)，粗軋和精軋前段工作輥、寬中厚板；粗軋和精軋工作輥及小型型鋼和棒材軋機(jī)精軋輥等。高鉻鑄鐵軋輥的熱處理有兩種形式，一是低于臨界轉(zhuǎn)變溫度的亞臨界熱處理，另一種是高于臨界點(diǎn)Ａ3的高溫?zé)崽幚怼８咩t軋輥表面材料的珠光體基體，希望具有極細(xì)的片間距，并在基體上有大量彌散分布的二次碳化物，要求有盡量低的殘余奧氏體和殘余應(yīng)力，所以一般選用后一種形式的熱處理，具體為正火加回火。上海軋輥規(guī)格是多少</p><p
