style="text-indent:25px">擠干輥在服役過(guò)程中,整個(gè)輥身受到周期性載荷作用，孔型是軋輥圓柱面上的一圈環(huán)槽，周期冷軋輥的孔型為變截面的環(huán)狀，每個(gè)徑向截面都是一段接近半圓的圓弧。以某450軋輥為例（見(jiàn)圖1），孔型沿周長(zhǎng)按功能分為五個(gè)部分，AB段是前回轉(zhuǎn)送進(jìn)段，形狀由大變小，起到軋坯導(dǎo)入的作用。BC段是后回轉(zhuǎn)送進(jìn)段，形狀不再變化，起到夾緊送進(jìn)作用。CD段是從BC段進(jìn)入DE段的過(guò)渡段之間，孔型尺寸快速由大變小，要光滑過(guò)渡。這三段的加工精度要求都不高。上海擠干輥廠家哪家便宜對(duì)擠干輥存在缺陷的原因分析，并采取相應(yīng)的措施，在很大程度上降低了成本。</p><div
