2）膠管硬度從邵爾A60度～90度不等，因此在購進膠管前要清楚制造廠家的制造工藝流程，對生產(chǎn)廠家的設(shè)備狀態(tài)及技術(shù)水平有一定的認(rèn)識； </p> <p> 3）進行小批量試驗，在成紗質(zhì)量穩(wěn)定的前提下進行中試； </p> <p> 4）大面積購進時，至少要進行一個車位的試驗，以多方面了解其生活波動、試紡性能以及品種適用性，并要經(jīng)不同季節(jié)（尤其是高溫、高濕季節(jié)）的車上運轉(zhuǎn)，考驗?zāi)z輥的抗繞花性、耐磨性，彈性恢復(fù)以及對化學(xué)涂料的滲透性能等，試驗合格后，方可進行大面積推廣。 </p> <p> <br />

?一般按用途分類。?其他采用特殊加工工藝的以外，都直接以材質(zhì)稱呼。如用電渣重熔鑄造坯料鍛壓的軋輥稱為電渣重熔鍛壓軋輥。軋輥的損壞原因：軋機部件中軋輥的工作條件比較為復(fù)雜。軋輥在制造和使用前的準(zhǔn)備工序中會產(chǎn)生殘余應(yīng)力和熱應(yīng)力。使用時又進一步受到了各種周期應(yīng)力的作用，包括有彎曲、扭轉(zhuǎn)、剪力、接觸應(yīng)力和熱應(yīng)力等。這些應(yīng)力沿輥身的分布是不均勻的、不斷變化的，其原因不*有設(shè)計因素。上海軋輥廠鑄造軋輥是指將冶煉鋼水或熔煉鐵水直接澆注成型制造的軋輥。</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(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(fù)磨而不用粗磨，磨削總量一般為0.3 mm～0.4 mm，可分三次進行，進刀量分別可為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值達到0.4 μm～0.6 μm為好。</p><p style="text-indent:25px">軋輥1.5%～2%Cr鍛鋼的比較終熱處理通常采用淬火加低溫回火，常見的淬火方式有感應(yīng)表面淬火和整體加熱淬火。其主要任務(wù)是考慮如何提高軋輥的耐磨性能、抗剝落性能，并提高淬硬層深度，盡量保證軋輥表面組織均勻，改善軋輥表層金屬組織的穩(wěn)定性。從20世紀(jì)70年代開始，隨著軋件合金化程度的提高，**度低合金結(jié)構(gòu)鋼(HSLA)的普遍應(yīng)用，軋件的強度和硬度也隨之增加，對軋輥材料的強度和硬度也提出了更高的要求，國際上普遍開始采用鉻含量約2%的Cr-Mo型或Cr-Mo-V型鋼工作輥，如我國一直使用的9cr2Mo、9Cr2MoV和86CrMov7、俄羅斯的9X2MΦ、西德的86Cr2MoV7、日本的MC2等。軋輥磁粉探傷原理：電磁學(xué)原理，磁化電流通過鐵磁性工件表面形成電磁場。</p><div

也可以減少膠輥膠圈的損壞和損傷,這也是棉紗質(zhì)量保持穩(wěn)定、減少棉紗疵點的重點。牽伸和卷繞部件隨著每天清潔次數(shù)的增加,飛花附入牽伸和卷繞部件的幾率降低,膠輥膠圈纏繞幾率下降,膠輥膠圈損傷、損壞的程度明顯下降;隨著紡紗號數(shù)的增加和棉紗質(zhì)量要求提高,膠輥膠圈纏繞、損傷、損壞的程度更加明顯,增加牽伸和卷繞部件的清潔頻次是行之有效的。在生產(chǎn)普通號數(shù)棉紗時,牽伸和卷繞部件每班清潔兩次膠輥膠圈的損傷、損壞只有牽伸和卷繞部件每天清潔一次的10%~20%。實踐證明,牽伸和卷繞部件合理的清潔頻次和適當(dāng)增加清潔頻次,是保證膠輥膠紡紗完整的重要環(huán)節(jié)。
