style="text-indent:25px">軋輥斷裂原因：1、脆性斷裂，此類軋輥斷口形狀較為平整，斷口周圍輥身表面較為齊整；?2、韌性斷裂，此類軋輥斷口形狀多呈"蘑菇頭"狀，斷口附近的輥身均成粉碎狀破碎。脆性斷裂和韌性斷裂都是因為軋輥應(yīng)力超過芯部強度造成的。其產(chǎn)生原因與軋輥本身殘余應(yīng)力，軋制時機械應(yīng)力以及軋輥熱應(yīng)力有關(guān)，特別是當(dāng)輥身的表面和芯部的溫差大時更容易產(chǎn)生。這種溫差可能由不良的輥冷卻，冷卻中斷或在新的軋制周期開始時軋輥表面過熱引起。軋輥的這種表面和芯部間的巨大溫差引起較大的熱應(yīng)力，當(dāng)較大的熱應(yīng)力，機械應(yīng)力以及軋輥的殘余應(yīng)力超過軋輥的芯部強度時引起斷輥。</p><p 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(yīng)加熱淬火法，目前后者在生產(chǎn)實踐中應(yīng)用更廣。在連續(xù)式感應(yīng)加熱淬火工藝方法中雙頻感應(yīng)淬火很有特色，它使用兩種不同頻率的感應(yīng)器匹配進行感應(yīng)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(yīng)器作為主感應(yīng)器，實現(xiàn)深層加熱，均熱一段時間后，再使用一個中頻感應(yīng)器來得到較深的經(jīng)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。冷軋輥的發(fā)展方向?qū)⑹窃谶M一步提**度硬度和淬硬層深度的同時，保證一定的韌性。</p><div

style="text-indent:25px">采用了球墨復(fù)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(xué)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。平面軋輥是即板帶軋機軋輥，其輥身呈圓柱形。上海軋輥有哪些</p><p

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(dǎo)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(jì)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。上海軋輥有哪些</p></p><br
