style="text-indent:25px">特殊軋輥：它用于鋼管軋機、車輪軋機、鋼球軋機及穿孔機等**軋機上。這種軋機的軋輥具有各種不同的形狀，如鋼管軋制中采用斜軋原理軋制的軋輥有圓錐形、腰鼓形或盤形。工作原理抗熱裂。通常對粗軋輥以強度、抗熱裂為主要要求；小型20輥軋機的工作軋輥重*100克左右，而寬厚板軋機的支承輥重量已超過200噸。選用軋輥時首先根據(jù)軋機對軋輥的基本強度要求，選定安全承載的主體材料（各種級別的鑄鐵、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量，對它以硬度、耐磨等為主要要求。然后考慮軋輥使用時所應有的耐磨性。在軋輥探傷中，常與其他探傷手段配合使用，提高探傷結果的可靠性。上海軋輥廠家哪家便宜</p><p

style="text-indent:25px">斷裂軋輥的外層組織中殘余奧氏體含量小于1%，故組織應力可以忽略不計。軋輥斷裂也可能與溫度不均勻造成的熱應力有關。軋輥在上機使用過程中，由于與軋材的緊密接觸，軋輥表面溫度迅速上升，而軋輥芯部的溫度上升較慢，這時軋輥面和軋輥芯部之間的溫差處于比較大值，溫差引起的軋輥熱應力也處于比較大值。如果軋輥的熱應力和軋輥的殘余應力相疊加，并且超過了軋輥芯部的強度極限時就可能發(fā)生軋輥斷裂的事故。防止斷裂應該從減小制造殘余應力，機械應力，組織應力和熱應力四方面進行。上海軋輥生產(chǎn)線</p><p
