style="text-indent:25px">軋輥的耐沖擊：對軋輥還有一些特殊要求，如壓下量大時，要求軋輥有較強的咬入能力，上海軋輥市場行情，耐沖擊性好；光潔度：軋制薄規(guī)格產(chǎn)品時，則對軋輥的剛性、組織性能均勻性、加工精度以及表面光潔度等要求較嚴；切削性能：軋制復雜斷面的型鋼時，還要考慮輥身工作層的切削加工性能等。選用軋輥時，對軋輥的有些性能要求往往是彼此對立的，軋輥購置費和維護費用又很昂貴，所以應(yīng)充分權(quán)衡技術(shù)和經(jīng)濟上的利弊，決定用鑄的還是鍛的，合金的還是非合金的，上海軋輥市場行情，上海軋輥市場行情，單一材料的還是復合材料的。軋輥1.5%～2%Cr鍛鋼的熱處理通常采用淬火加低溫回火。上海軋輥市場行情</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海軋輥市場行情,軋輥"

style="text-indent:25px">傳統(tǒng)熱軋輥材料的選用及熱處理工藝熱軋輥常工作在700℃～800℃的高溫環(huán)境，與灼熱的鋼坯相接觸，需要承受強大的軋制力，同時表面要承受軋材的強力磨損，反復被熱軋材加熱及冷卻水冷卻，經(jīng)受溫度變化幅度較大的熱疲勞作用。這就要求熱軋輥材料必須具有高的淬透性、低的熱膨脹系數(shù)、高的熱傳導能力和高的高溫屈服強度及高的抗氧化性。國內(nèi)曾經(jīng)使用過鍛鋼軋輥和無限冷硬鑄鐵軋輥，除普通冷硬鑄鐵外，還有低鎳鉻鉬、中鎳鉻鉬、高鎳鉻鉬鑄鐵材料，比較好次的冷硬鑄鐵材料為高鎳鉻鉬冷硬鑄鐵。這類材質(zhì)軋輥的缺點是硬度低，耐磨性不好。上海軋輥規(guī)格鑄鐵軋輥正火的目的是增加基體中的珠光體或索氏體組織的數(shù)目和彌散度。</p><div

style="text-indent:25px">磨床對膠輥的磨礪是通過砂輪與膠輥精確穩(wěn)定的相對運動，由砂輪的微粒鋒刃對膠輥表面進行磨削，磨床和砂輪的質(zhì)量與其穩(wěn)定性直接影響膠輥表面的磨礪質(zhì)量。通常選用粒度為(40～80)號大氣孔綠碳化硅或碳化硅砂輪，且要選用中低硬度的砂輪，太硬的磨粒變鈍后不能順利脫落，磨削力和熱量增加影響磨礪后膠輥表面質(zhì)量。砂輪使用前必須調(diào)平衡并且修整，砂輪兩棱應(yīng)用舊砂輪或油石倒角。目前，棉紡企業(yè)復磨并條膠輥使用的大多數(shù)磨床仍為FLJ804型等設(shè)備，其使用年限較長，磨礪膠輥前應(yīng)確保具有良好的機械性能，特別是砂輪主軸、車頭主軸的跳動應(yīng)不大于0.0l mm，要求其旋轉(zhuǎn)平穩(wěn)，振動小。</p><p style="text-indent:25px">軋輥的工作條件：使用時又進一步受到了各種周期應(yīng)力的作用，決定于三個因素：①軋機、軋材和軋制條件，以及軋輥的合理選擇；②軋輥材料及其制造質(zhì)量；③軋輥的使用和維護制度。軋輥品種。鑄鐵軋輥：一般按制造工藝分類：工作層因金屬型的激冷作用呈白口組織（基體+碳化物）的軋輥稱冷硬鑄鐵軋輥；用上述方法，但適當提高鐵水碳當量而得到麻口組織（基體+碳化物+石墨）的軋輥稱無限冷硬鑄鐵軋輥。采用襯砂金屬型并繼續(xù)提高碳當量可得粗麻口組織的軋輥，稱半冷硬鑄鐵軋輥。所有上述品種的組織中凡石墨呈球狀的，稱球墨鑄鐵軋輥；復合澆鑄的軋輥加“復合”一詞。熱軋輥薄板粗軋機架采用半高速鋼軋輥，其耐磨性是高鉻鋼軋輥的2倍。</p><div

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格要求，主要是保證膠輥表面圓柱度。粗磨后不應(yīng)立即進行精磨，要將并條膠輥放置48 h，使其經(jīng)時效處理后進行。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*需進行復磨而不用粗磨，磨削總量一般為0.3 mm～0.4 mm，可分三次進行，進刀量分別可為0.2 mm、0.1 mm、0.1 mm，采用小負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值達到0.4 μm～0.6 μm為好。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)展進行了展望。上海軋輥規(guī)格</p><p
