style="text-indent:25px">軋輥的工作條件：使用時又進(jìn)一步受到了各種周期應(yīng)力的作用，決定于三個因素：①軋機(jī)、軋材和軋制條件，以及軋輥的合理選擇；②軋輥材料及其制造質(zhì)量；③軋輥的使用和維護(hù)制度。軋輥品種。鑄鐵軋輥：一般按制造工藝分類：工作層因金屬型的激冷作用呈白口組織（基體+碳化物）的軋輥稱冷硬鑄鐵軋輥；用上述方法，但適當(dāng)提高鐵水碳當(dāng)量而得到麻口組織（基體+碳化物+石墨）的軋輥稱無限冷硬鑄鐵軋輥。采用襯砂金屬型并繼續(xù)提高碳當(dāng)量可得粗麻口組織的軋輥，稱半冷硬鑄鐵軋輥。所有上述品種的組織中凡石墨呈球狀的，稱球墨鑄鐵軋輥；復(fù)合澆鑄的軋輥加“復(fù)合”一詞。</p><p style="text-indent:25px">軋輥磁粉探傷原理：電磁學(xué)原理，磁化電流通過鐵磁性工件表面形成電磁場，缺陷的存在會切斷磁力線，形成漏磁場并吸附磁粉，磁粉堆積形成磁痕，通過觀察磁痕來判斷缺陷的存在（磁痕實質(zhì)上就是放大了的缺陷）。磁粉探傷技術(shù)的優(yōu)點：（1）確定表面和次表面線形不連續(xù)缺陷；（2）操作和解釋相對簡單。磁粉探傷技術(shù)的缺點：（1）只能使用在鐵磁體材質(zhì)上；（2）局限于表面缺陷的探傷。2、滲透著色探傷滲透著色探傷由于使用簡單，滲透著色探傷普遍地用于軋輥表面裂紋檢查。比較常見的是用紅色染料，可以用噴霧的方法來施加。軋輥的內(nèi)部質(zhì)量則決定著軋輥的使用壽命的長短。</p><div

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(jī)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(jìn)行良好的冷卻。制造殘余應(yīng)力，機(jī)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。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。上海軋輥有哪些</p><p
