style="text-indent:25px">一般情況下軋輥大部分制造殘余應(yīng)力會在熱處理過程中消除，并且會隨著軋輥的存放時間延長而逐漸消除，因此新軋輥存放一段時間再使用，能夠降低斷輥風(fēng)險。避免較大機械應(yīng)力的方法主要是避免過冷鋼。降低組織應(yīng)力的方法是通過熱處理將輥身工作層殘余奧氏體含量控制在小于5%以下。減小熱應(yīng)力的辦法是在軋鋼過程中對軋輥進行良好的冷卻。制造殘余應(yīng)力，機械應(yīng)力，組織應(yīng)力和熱應(yīng)力是造成高鉻鋼軋輥斷裂的主要原因，良好的熱處理，軋制條件和冷卻可以有效防治高鉻鋼軋輥斷裂。軋輥的工作條件是使用時又進一步受到了各種周期應(yīng)力的作用。上海軋輥規(guī)格</p><p

style="text-indent:25px">軋輥1.5%～2%Cr鍛鋼的比較終熱處理通常采用淬火加低溫回火，常見的淬火方式有感應(yīng)表面淬火和整體加熱淬火。其主要任務(wù)是考慮如何提高軋輥的耐磨性能、抗剝落性能，并提高淬硬層深度，盡量保證軋輥表面組織均勻，改善軋輥表層金屬組織的穩(wěn)定性。從20世紀(jì)70年代開始，隨著軋件合金化程度的提高，**度低合金結(jié)構(gòu)鋼(HSLA)的普遍應(yīng)用，軋件的強度和硬度也隨之增加，對軋輥材料的強度和硬度也提出了更高的要求，國際上普遍開始采用鉻含量約2%的Cr-Mo型或Cr-Mo-V型鋼工作輥，如我國一直使用的9cr2Mo、9Cr2MoV和86CrMov7、俄羅斯的9X2MΦ、西德的86Cr2MoV7、日本的MC2等。上海軋輥規(guī)格</p><p
