style="text-indent:25px">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。傳統(tǒng)冷軋輥材料及其熱處理方式冷軋輥在工作過程中要承受很大的軋制壓力，加上軋件的焊縫、夾雜、邊裂等問題，容易導致瞬間高溫，使工作輥受到強烈熱沖擊造成裂紋、粘輥甚至剝落而報廢。因此，冷軋輥要有抵抗因彎曲、扭轉(zhuǎn)、剪切應(yīng)力引起的開裂和剝落的能力，同時也要有高的耐磨性、接觸疲勞強度、斷裂韌性和熱沖擊強度等。國內(nèi)外冷軋工作輥一般使用的材質(zhì)有GCr19、9Cr2、9Cr、9CrV、9cr2W、9Cr2Mo、60CrMoV、80CrNi3W、8CrMoV、86CrMoV7、Mo3A等。20世紀50～60年代，這一時期的軋件多為碳素結(jié)構(gòu)鋼，強度和硬度不高，所以軋輥一般采用1.5%～2%Cr鍛鋼。</p><p style="text-indent:25px">采用了球墨復合鑄鐵軋輥，相對而言，使用壽命提高了幾倍，至今仍然在使用。國外則一般采用半鋼和高硬度特殊半鋼材質(zhì)，對克服表面粗糙和抗磨損都很有效。為了提高熱軋輥的表面耐磨性，熱軋輥的材料不斷地得到改進，其基本的發(fā)展過程是從冷硬鑄鐵到高鉻鑄鐵到半高速鋼和高速鋼。高鉻鑄鐵軋輥的化學成分為：2.0%～4.0%Ｃ，10%～30%Ｃｒ，0.15%～1.6%Ｎｉ，0.3%～2.9%Ｍｏ。其本質(zhì)是一種高耐磨性的高合金白口鐵，鉻含量一般在10%～15%，其碳化物主要是Ｍ7Ｃ3型，與白口鑄鐵的連續(xù)的Ｍ8Ｃ型碳化物不同，它不但具有良好的耐磨性，還有較高的硬度(ＨＶ可達1800)，基體為奧氏體、馬氏體，因而其硬度和韌性結(jié)合較好。軋輥按制造方法又可分為整體鑄造軋輥和復合鑄造軋輥兩類。</p><div

style="text-indent:25px">軋輥冷焊修補方法：冷焊機是利用電火花高頻放電原理對金屬表面進行無熱堆焊，因而在修補軋輥砂眼、劃傷等缺陷過程中不變形、不退火、不咬邊和殘余應(yīng)力，不改變金屬組織狀態(tài)。修復精度高，涂層厚度從幾微米到幾毫米，可對金屬工件出現(xiàn)磨損、劃傷、小洞、裂紋、缺損變形、硬度降低、沙眼、損傷等缺陷進行沉積、封孔、補平等修復功能，只須打磨、拋光，也可進行車、銑、刨、磨等各類機械加工，以及電鍍等后期加工。軋輥的冷焊操作方法比較麻煩一些。合理選材及采用合適的熱處理方式高質(zhì)量地制造軋輥，可以節(jié)約大量的輥材。上海軋輥排行榜</p><p

膠輥作為重要的牽伸元件，其性能、管理水平都與成紗質(zhì)量密切相關(guān)。使用廠家不僅要注重其制作工藝及磨礪精度，膠輥的后續(xù)使用、管理與維護對確保膠輥紡紗性能的優(yōu)良及穩(wěn)定也非常重要，二者應(yīng)相輔相成才能達到穩(wěn)定的紡紗質(zhì)量水平。我們本著“認真選型、嚴把質(zhì)量、精細制作、分區(qū)管理、以國產(chǎn)逐步替代進口”的原則，對膠輥進行全過程管理。 </p> <p> <br /> </p> <p> 批量購進膠管（包括新品膠管或者選擇新的膠管制造廠家）前，要對所選膠管型號、規(guī)格、性能、紡紗質(zhì)量做到心中有數(shù)，具體做法是： </p> <p> 1）由于現(xiàn)在全國制造膠管的廠家眾多、品種繁雜，因此首先要對制造廠家進行了解； </p> <p> 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，彈性恢復以及對化學涂料的滲透性能等，試驗合格后，方可進行大面積推廣。 </p> <p> <br /> 上海軋輥排行榜</p><p
