style="text-indent:25px">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，缺陷的存在會切斷磁力線，形成漏磁場并吸附磁粉，磁粉堆積形成磁痕，通過觀察磁痕來判斷缺陷的存在（磁痕實質(zhì)上就是放大了的缺陷）。磁粉探傷技術(shù)的優(yōu)點：（1）確定表面和次表面線形不連續(xù)缺陷；（2）操作和解釋相對簡單。磁粉探傷技術(shù)的缺點：（1）只能使用在鐵磁體材質(zhì)上；（2）局限于表面缺陷的探傷。2、滲透著色探傷滲透著色探傷由于使用簡單，滲透著色探傷普遍地用于軋輥表面裂紋檢查。比較常見的是用紅色染料，可以用噴霧的方法來施加。</p><p style="text-indent:25px">鑄鋼軋輥 ?：一般按含碳量分類：含碳極高（1.4～2.4%）的過共析鋼軋輥，俗稱半鋼軋輥，高碳的半鋼軋輥實際已伸入鑄鐵領(lǐng)域；高碳過共析鋼軋輥還有一類為石墨鋼軋輥，其石墨是通過孕育和熱處理獲得的。：鍛鋼軋輥 ?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(jī)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(jìn)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，其原因不僅有設(shè)計因素。軋輥按成形方法分為鑄造軋輥和鍛造軋輥，按工藝方法分為整體軋輥、冶金復(fù)合軋輥和組合軋輥。</p><div

膠輥的質(zhì)量主要取決于膠料的配方設(shè)計，丁腈橡膠(NBR)仍是目前紡紗膠輥的優(yōu)先膠種。配方的確定需要進(jìn)行大量的試驗，其中對性能影響較大的幾種材料可以采用正交法設(shè)計多組方案，再通過機(jī)械性能比較進(jìn)行優(yōu)化，以篩選出理想的配方設(shè)計。 </p> <p> 并條機(jī)膠輥的成型方式一般有三種：直接包膠模壓硫化；膠管擠出一硫化罐硫化成型；鋁襯管膠管套裝成型。第一種成型工藝缺點是效率低、成本高，但比較大優(yōu)點是膠層密實，膠層與輥芯粘結(jié)牢靠而不會出現(xiàn)脫輥現(xiàn)象，使用壽命長。后兩種制造工藝使用的成型設(shè)備主要為擠出機(jī)和硫化罐，是現(xiàn)在膠輥制造企業(yè)普遍采用的成型工藝。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。上海軋輥咨詢電話</p><p

style="text-indent:25px">目前5萬錠~16萬錠的生產(chǎn)車間有幾個或十幾個棉紗品種和各種不同硬度、厚度、磨礪次數(shù)的膠輥膠圈,給紡紗廠生產(chǎn)車間的膠輥膠圈管理帶來了諸多不便。即使采用備用膠輥膠圈更換,也會造成不同硬度、磨礪次數(shù)、厚度的膠輥膠圈在同一臺紡紗設(shè)備上使用。膠輥膠圈管理和生產(chǎn)車間管理較好的大紡紗車間,盡管都采用標(biāo)記來區(qū)分不同硬度、厚度、磨礪次數(shù)的膠輥膠圈,但在處理某一臺細(xì)紗機(jī)或某一區(qū)域細(xì)紗機(jī)膠輥膠圈時,仍會發(fā)現(xiàn)混雜有不同厚度、硬度、磨礪次數(shù)的膠輥膠圈。很多紡紗廠膠輥膠圈處理室為紡紗車間不同品種準(zhǔn)備了不同的備用膠輥膠圈便于中夜班更換,但是沒有考慮到不同生產(chǎn)品種對膠輥膠圈的消耗程度不同,也沒有考慮膠輥膠圈在磨礪次數(shù)、厚度、硬度方面相差較大時,更換膠輥膠圈會造成棉紗質(zhì)量存在較大偏差和變異,嚴(yán)重影響棉紗質(zhì)量,導(dǎo)致質(zhì)量投訴。適當(dāng)?shù)膶^大規(guī)模生產(chǎn)車間減少棉紗品種的多樣性生產(chǎn)、嚴(yán)格執(zhí)行大車間紡紗機(jī)臺區(qū)域管理控制、建立嚴(yán)格統(tǒng)一的標(biāo)準(zhǔn)化膠輥膠圈損傷和損壞更換模式、加強(qiáng)設(shè)備維護(hù)與保養(yǎng)、強(qiáng)化紡紗膠輥膠圈的檢查與交接班是減少紡紗廠生產(chǎn)車間膠輥膠圈亂象的重點。表5是不同規(guī)模紡紗廠細(xì)紗車間膠輥膠圈混雜一個月的統(tǒng)計匯總。上海軋輥工廠</p><p
