style="text-indent:25px">為提高軋輥淬硬層深及接觸疲勞壽命，降低淬硬層脆性及過熱敏感性，同時也為滿足軋件對冷軋工作輥力學(xué)性能和使用性能的進(jìn)一步要求，自20世紀(jì)80年代中、后期，國外軋輥生產(chǎn)廠對5%Ｃｒ冷軋輥鋼進(jìn)行了化學(xué)成分的優(yōu)化工作，主要是在5%Ｃｒ鋼中增加鉬、釩的含量或加入鈦、鎳等元素。添加0.1%左右鈦的5%Ｃｒ鋼軋輥中，鈦以碳氮化合物(ＴｉＣＮ)形式在基體中微細(xì)析出，經(jīng)過摩擦損耗后ＴｉＣＮ脫落，在軋輥表面形成劃痕，使適度的粗度再生。在鍍錫板軋機(jī)的實(shí)際操作中，有效利用粗糙度降低小的優(yōu)點(diǎn)，從軋制初期就可高速軋制。</p><p style="text-indent:25px">實(shí)際的軋輥生產(chǎn)表明，高鉻鑄鐵軋輥有較好的抗熱裂性能，原因是軋輥表面生成一層致密且有韌性的鉻的氧化膜，能減少熱裂紋的數(shù)量和深度。因此，高鉻鑄鐵輥在20世紀(jì)80年代被非常普遍用于精軋前架。目前，高鉻鑄鐵復(fù)合軋輥已普遍用作熱軋帶 (鋼)連軋機(jī)，粗軋和精軋前段工作輥、寬中厚板；粗軋和精軋工作輥及小型型鋼和棒材軋機(jī)精軋輥等。高鉻鑄鐵軋輥的熱處理有兩種形式，一是低于臨界轉(zhuǎn)變溫度的亞臨界熱處理，另一種是高于臨界點(diǎn)Ａ3的高溫?zé)崽幚?。高鉻軋輥表面材料的珠光體基體，希望具有極細(xì)的片間距，并在基體上有大量彌散分布的二次碳化物，要求有盡量低的殘余奧氏體和殘余應(yīng)力，所以一般選用后一種形式的熱處理，具體為正火加回火。軋輥常用的熱處理類型：去應(yīng)力退火、等溫球化退火、擴(kuò)散退火、正火、回火、淬火、深冷處理。</p><div
