style="text-indent:25px">汽車軸承對(duì)材質(zhì)的冶煉要求非常高：滾動(dòng)軸承的質(zhì)量很大水平上與汽車軸承用鋼的質(zhì)量有著緊密的聯(lián)系。由于汽車軸承鋼所具有的特性，對(duì)冶煉質(zhì)量的要求比一般工業(yè)用鋼要嚴(yán)格得多，如鋼的化學(xué)成分、純度、組織和結(jié)構(gòu)均勻性等。一、嚴(yán)格的化學(xué)成分要求，金華汽車配件在哪里買。一般汽車軸承用鋼主要是高碳鉻軸承鋼，即含碳量1％左右，加入1．5％左右的鉻，并含有少量的錳、硅元素的過(guò)共析鋼。鉻可以改善熱處理性能，金華汽車配件在哪里買、提高淬透性，金華汽車配件在哪里買、組織均勻性、回火穩(wěn)定性，又可以提高鋼的防銹性能和磨削性能。但當(dāng)鉻含量超過(guò)1．65％時(shí)，淬火后會(huì)增加鋼中剩余奧氏體，降低硬度和尺寸穩(wěn)定性，增加碳化物的不均勻性，降低鋼的沖擊韌性和疲勞強(qiáng)度。為此，高碳鉻汽車軸承鋼中的含鉻量一般控制在1.65％以下。只有嚴(yán)格控制汽車軸承鋼中的化學(xué)成分的含量，才可通過(guò)熱處置工序獲得滿足汽車軸承性能的組織和硬度。二、嚴(yán)格高精度的尺寸要求。正常運(yùn)行時(shí)，油脂會(huì)由汽車軸承座甩到軸承內(nèi)。金華汽車配件在哪里買</p><div
