style="text-indent:25px">特殊軋輥：它用于鋼管軋機(jī)、車(chē)輪軋機(jī)、鋼球軋機(jī)及穿孔機(jī)等**軋機(jī)上。這種軋機(jī)的軋輥具有各種不同的形狀，如鋼管軋制中采用斜軋?jiān)碥堉频能堓佊袌A錐形、腰鼓形或盤(pán)形。工作原理抗熱裂。通常對(duì)粗軋輥以強(qiáng)度、抗熱裂為主要要求；小型20輥軋機(jī)的工作軋輥重*100克左右，而寬厚板軋機(jī)的支承輥重量已超過(guò)200噸。選用軋輥時(shí)首先根據(jù)軋機(jī)對(duì)軋輥的基本強(qiáng)度要求，選定安全承載的主體材料（各種級(jí)別的鑄鐵、鑄鋼或鍛鋼等）。?硬度。而精軋輥速度較高，軋制比較終產(chǎn)品要有一定的表面質(zhì)量，對(duì)它以硬度、耐磨等為主要要求。然后考慮軋輥使用時(shí)所應(yīng)有的耐磨性。</p><p style="text-indent:25px">軋輥在使用中磨損、溫度和輥形的不斷變化。此外，軋制條件經(jīng)常會(huì)出現(xiàn)異常情況。軋輥在使用后冷卻不當(dāng)，也會(huì)受到熱應(yīng)力的損害。所以軋輥除磨損外，還經(jīng)常出現(xiàn)裂紋、斷裂、剝落、壓痕等各種局部損傷和表面損傷。一個(gè)好的軋輥，其強(qiáng)度、耐磨性和其他各種性能指標(biāo)間應(yīng)有較優(yōu)的匹配。這樣，不*在正常軋制條件下持久耐用，又能在出現(xiàn)某些異常軋制情況時(shí)損傷較小。所以在制造軋輥時(shí)要嚴(yán)格控制軋輥的冶金質(zhì)量或輔以外部措施以增強(qiáng)軋輥的承載能力。合理的輥形、孔型、變形制度和軋制條件也能減小軋輥工作負(fù)荷，避免局部高峰應(yīng)力，延長(zhǎng)軋輥壽命。直接接觸軋件的軋輥稱(chēng)工作軋輥；</p><div

style="text-indent:25px">雖然軋輥的探傷方法也有很多種，但是總的來(lái)說(shuō)都是為了將軋輥上各種各樣的缺陷去除干凈，以保證軋線用輥的表面質(zhì)量和內(nèi)部質(zhì)量的合格，為了達(dá)到此目的，現(xiàn)在軋輥探傷向著自動(dòng)化（安裝在軋輥磨床上）、綜合化（幾種探傷方法聯(lián)合使用）、專(zhuān)業(yè)化（設(shè)置專(zhuān)業(yè)探傷人員）的方向發(fā)展。我們現(xiàn)有的探傷水平有待提高，我們努力學(xué)習(xí)掌握更先進(jìn)的探傷技術(shù)和探傷經(jīng)驗(yàn)。軋輥的壽命主要取決于軋輥的內(nèi)在性能和工作受力。內(nèi)在性能包括強(qiáng)度和硬度等方面。要使軋輥具有足夠的強(qiáng)度，主要從軋輥材料方面來(lái)考慮；硬度通常是指軋輥工作表面的硬度，它決定軋輥的耐磨性，在一定程度上也決定軋輥的使用壽命，通過(guò)合理的材料選用和熱處理方式可以滿(mǎn)足軋輥的硬度要求。冷軋輥輥身表面應(yīng)有高而均勻的硬度，其優(yōu)劣表現(xiàn)在輥身工作層的耐磨性，即耐粗糙性。上海軋輥哪家專(zhuān)業(yè)</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(shí)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(jìn)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(shì)。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(shí)現(xiàn)深層加熱，均熱一段時(shí)間后，再使用一個(gè)中頻感應(yīng)器來(lái)得到較深的經(jīng)過(guò)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。上海軋輥廠商哪家好</p></p><br
