⑷特硬輥：肖氏硬度約為85~100，用于冷軋機(jī)。軋機(jī)類(lèi)型：按軋機(jī)類(lèi)型軋輥可分為以下三類(lèi)： ⑴平面軋輥：即板帶軋機(jī)軋輥，其輥身呈圓柱形。一般熱軋鋼板軋機(jī)軋輥?zhàn)龀晌夹?，受熱膨脹時(shí)，可獲得較好的板形；冷軋鋼板軋機(jī)軋輥?zhàn)龀晌⑼剐危谲堉茣r(shí)，軋輥產(chǎn)生彎曲，以獲得良好的板形。⑵帶槽軋輥：它用于軋制大、中、小各種型鋼、線(xiàn)材及初軋開(kāi)坯。在輥面上刻有軋槽使軋件成形。上海軋輥批發(fā)公司斷裂軋輥的外層組織中殘余奧氏體含量小于1%，故組織應(yīng)力可以忽略不計(jì)。</p><div

style="text-indent:25px">軋輥的耐沖擊：對(duì)軋輥還有一些特殊要求，如壓下量大時(shí)，要求軋輥有較強(qiáng)的咬入能力，耐沖擊性好；光潔度：軋制薄規(guī)格產(chǎn)品時(shí)，則對(duì)軋輥的剛性、組織性能均勻性、加工精度以及表面光潔度等要求較嚴(yán)；切削性能：軋制復(fù)雜斷面的型鋼時(shí)，還要考慮輥身工作層的切削加工性能等。選用軋輥時(shí)，對(duì)軋輥的有些性能要求往往是彼此對(duì)立的，軋輥購(gòu)置費(fèi)和維護(hù)費(fèi)用又很昂貴，所以應(yīng)充分權(quán)衡技術(shù)和經(jīng)濟(jì)上的利弊，決定用鑄的還是鍛的，合金的還是非合金的，單一材料的還是復(fù)合材料的。</p><p style="text-indent:25px">是否接觸軋件分為工作軋輥和支承輥。直接接觸軋件的軋輥稱(chēng)工作軋輥；為增加工作軋輥的剛度和強(qiáng)度而置于工作軋輥背面或側(cè)面又不直接接觸軋件的軋輥稱(chēng)支承輥。按使用機(jī)架分為初軋輥、粗軋輥、中間軋輥和精軋輥。按軋材的品種分為板帶軋輥、軌梁軋輥、線(xiàn)材軋輥和管材軋輥等。還可按軋制時(shí)軋件的狀態(tài)分為熱軋輥和冷軋輥。按硬度值 ⑴軟輥：肖氏硬度約為30~40，用于開(kāi)坯機(jī)、大型型鋼軋機(jī)的粗軋機(jī)等。⑵半硬輥：肖氏硬度約為40~60，用于大型、中型、小型型鋼軋機(jī)和鋼板軋機(jī)的粗軋機(jī)。熱軋輥薄板粗軋機(jī)架采用半高速鋼軋輥，其耐磨性是高鉻鋼軋輥的2倍。</p><div style="width:100%;text-align: center;"><img
