style="text-indent:25px">軋輥表面淬火方法按加熱方法可分整體快速加熱淬火法和連續(xù)感應加熱淬火法，目前后者在生產實踐中應用更廣。在連續(xù)式感應加熱淬火工藝方法中雙頻感應淬火很有特色，它使用兩種不同頻率的感應器匹配進行感應加熱，在輥面溫度控制和加熱層溫度分布方面的具有明顯的優(yōu)勢。典型的雙頻淬火裝備以電流透入深度較大的工頻感應器作為主感應器，實現(xiàn)深層加熱，均熱一段時間后，再使用一個中頻感應器來得到較深的經過等溫的奧氏體化層,淬后獲得所需的淬硬層深度。中頻電源以250Hz為佳，也有使用500、1000、1200和2500Hz。上海軋輥品牌軋輥是使（軋材）金屬產生塑性變形的工具。</p><div

style="text-indent:25px">軋輥對組織應力影響比較大的就是外層組織中殘余奧氏體含量。殘余奧氏體在軋制溫度，軋制壓力和水冷的交變作用下，發(fā)生奧氏體向馬氏體或貝氏體的轉變，由于奧氏體的比容小，而馬氏體的比容大，因而在組織轉變的過程中伴隨著體積的膨脹，會致使軋輥的工作層產生更大的壓應力，芯部產生更大的拉應力，芯部應力一旦超過材料的強度，必然造成軋輥斷裂?？紤]到殘余奧氏體對組織應力的影響及熱帶連軋機軋輥的工作條件，一般軋輥的殘余奧氏體含量控制在小于5%即可保證安全使用。</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，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合較好。軋輥的工作條件是使用時又進一步受到了各種周期應力的作用。</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。粗磨后不應立即進行精磨，要將并條膠輥放置48 h，使其經時效處理后進行。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，為保證磨礪質量，一般砂輪主軸轉速為1800 r/min，相應車頭轉速約為200 r/min。磨削前需要調整好磨床尾座，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。軋輥在熱處理過程中，對軋輥鋼的淬火和加熱限制在奧氏體中含碳量不超過0.6%的程度。上海軋輥一般多少錢</p><p

</p> <p> 3）磨礪量應控制在0.15 mm以內。磨礪量大，膠輥受壓大，產生熱量大，易灼傷膠輥表面而影響膠輥性能。 </p> <p> 4）對于免處理膠輥在制作過程中，根據(jù)品種需要考慮是否進行光照處理。試驗證明，免處理膠輥經光照處理后成紗質量有所提高，但光照處理的時間應掌握適當，試驗結果見表1。 </p> <p> 從試驗數(shù)據(jù)來看：膠輥的表面粗糙度并不是越小越好，應掌握在0.5 μm左右；當然，表面粗糙度值還應根據(jù)纖維性質、所紡品種號數(shù)來確定。上海軋輥供應</p><p
