style="text-indent:25px">熱軋輥工作在交變的高溫和力的作用下，其表面反復(fù)受到摩擦，會產(chǎn)生強烈的磨損，因此熱軋輥的發(fā)展主要在于進一步提高其耐磨性。在實際的軋制生產(chǎn)中，表面淬火和滲碳強化處理的熱軋輥己不能滿足對其高耐磨性的要求，但整體的高速鋼或硬質(zhì)合金軋輥成本極高，對于軋輥芯部材料將造成浪費。因此，軋輥的生產(chǎn)迫切需要進行表面處理，將硬質(zhì)合金或陶瓷材料熔覆在軋輥的表面作為軋輥的工作表層。表面鍍鉻、火焰噴涂、等離子噴涂以及激光毛化都是工具表面合金強化技術(shù)，將進一步用于提高的軋輥的性能。軋輥按成形方法分為鑄造軋輥和鍛造軋輥，按工藝方法分為整體軋輥、冶金復(fù)合軋輥和組合軋輥。上海軋輥制造廠家</p><p

style="text-indent:25px">軋輥渦流檢測原理：渦流檢測是建立在電磁感應(yīng)原理基礎(chǔ)之上的一種無損檢測方法，它適用于導(dǎo)電材料。當(dāng)把一塊導(dǎo)體置于交變磁場之中，在導(dǎo)體中就有感應(yīng)電流存在，即產(chǎn)生渦流。由于導(dǎo)體自身各種因素（如電導(dǎo)率、磁導(dǎo)率、形狀，尺寸和缺陷等）的變化，會導(dǎo)致渦流的變化，利用這種現(xiàn)象判定導(dǎo)體性質(zhì)，狀態(tài)的檢測方法，叫渦流檢測。渦流探傷的優(yōu)點：1、檢測時，線圈不需要接觸工件，也無需耦合介質(zhì)，所以檢測速度快。2、對工件表面或近表面的缺陷，有很高的檢出靈敏度，且在一定的范圍內(nèi)具有良好的線性指示，可用作質(zhì)量管理與控制。3、能測量金屬覆蓋層或非金屬涂層的厚度。上海軋輥制造廠家</p></p><br
