一般來(lái)說(shuō),低鉻球含鉻量為0.5%到2.5%,含碳量從1.80%到3.20%。因此,根據(jù)國(guó)家標(biāo)準(zhǔn),低鉻球硬度應(yīng)該不小于45hrc，沖擊值應(yīng)該不小于1.5j/cm2。低鉻球也需要高溫度回火處理來(lái)保證質(zhì)量。這種處理可以消除鑄造應(yīng)力。如果鋼球的表面呈深紅色,表明經(jīng)過(guò)了高溫回火處理，上海庫(kù)存鋼球推薦廠家。如果表面仍然呈金屬本色,表明鋼球沒(méi)經(jīng)過(guò)高溫回火。

鋼球開(kāi)裂原因分析：某公司送檢成品鋼球5粒（斷裂成半粒的鋼球），材料為GCr15軸承鋼，加工工藝過(guò)程如下：φ6.0mm熱軋盤(pán)圓（連鑄）→球化退火后冷拔成φ4.5mm→去應(yīng)力退火后冷拔成φ3.2mm→去應(yīng)力退火后冷拔成φ2.5mm→冷鐓成鋼球→冷、熱加工成φ2.36mm成品鋼球。該批次鋼球共300萬(wàn)粒，用戶(hù)在使用過(guò)程中發(fā)現(xiàn)約60粒開(kāi)裂成兩半，要求對(duì)鋼球發(fā)生開(kāi)裂的原因進(jìn)行分析。 </p> <p> 觀察與分析 </p> <p> 宏觀形貌 </p> <p> 送檢的5個(gè)半粒鋼球斷口的中心部位材料均呈現(xiàn)為線狀分布，邊緣光亮且凹凸不平，具有明顯的擠壓、磨損痕跡。接下來(lái)進(jìn)行斷口的微觀形貌觀察與分析： </p> <p> 為了更詳細(xì)地觀察缺點(diǎn)形貌，任取半粒鋼球放置在JSM-6380LV掃描電子顯微鏡下變倍觀察斷口形貌，結(jié)果表明：鋼球中心部位約五分之三斷口呈現(xiàn)為深淺不一平行的條帶狀，形貌自然、疏松，其余部位主要呈現(xiàn)為擠壓、磨損狀態(tài)，局部為瓷狀斷裂面，斷口的微觀形貌見(jiàn)圖2～圖5。采用EDS7582能譜儀對(duì)條帶處的多處部位進(jìn)行微區(qū)成分分析，發(fā)現(xiàn)材料內(nèi)存在異常元素，主要為氧、鈣、鎂及微量的鈉。 </p><p> 鋼球等溫淬火 </p> <p> 將奧氏體化鋼球加熱到320°C并在硝酸鉀的鹽浴中，等溫保持足夠長(zhǎng)的時(shí)間，使之轉(zhuǎn)化為下貝氏體組織，然后取出在空氣中冷卻。下貝氏體組織的強(qiáng)度、硬度較高而韌性良好，提高了鋼球的綜合力學(xué)性能。等溫淬火減小了鋼球與淬火介質(zhì)的溫差，從而減小了淬火應(yīng)力，又由于貝氏體的體積比馬氏體小，而且鋼球內(nèi)外溫度一致，故淬火組織應(yīng)力也小。等溫淬火可以較好減小鋼球變形和開(kāi)裂傾向。 </p> <p> 鋼球回火 </p> <p> 當(dāng)鋼球全淬成馬氏體再加熱到150°C-170°C回火時(shí)，隨著回火溫度升高，按其內(nèi)部組織結(jié)構(gòu)變化，分四個(gè)階段進(jìn)行： </p> <p> <br /> </p> <p>

球磨機(jī)鋼球是球磨機(jī)重要的基礎(chǔ)零部件，尤其是精密工業(yè)鋼球在國(guó)民經(jīng)濟(jì)發(fā)展中起著巨大作用。較廣用于水泥廠，發(fā)電廠等。高低鉻多元素合金鋼球，高低鉻多元素合金鑄鍛，在國(guó)民經(jīng)濟(jì)發(fā)展中起著巨大作用。 </p> <p> 在一些特殊條件下，常常需要特殊材質(zhì)的鋼球，來(lái)完成不同環(huán)境下所要求達(dá)到的功能。其實(shí)一些特殊材質(zhì)鋼球已較廣應(yīng)用于國(guó)民經(jīng)濟(jì)各個(gè)領(lǐng)域中，包括高鉻鋼球;高鉻鋼鍛;低鉻鋼球;低鉻鋼鍛;鉻系列襯板;錳系列襯板;錘頭;多元合金鋼球;多元合金襯板;各種耐磨材料。它們的推廣應(yīng)用，不*推動(dòng)了球磨機(jī)鋼球生產(chǎn)業(yè)的發(fā)展，而且也促進(jìn)了相關(guān)行業(yè)的技術(shù)發(fā)展和科技進(jìn)步。 </p> <p> <br /> </p> <p> 球磨機(jī)經(jīng)過(guò)一段時(shí)間運(yùn)轉(zhuǎn)，每7～10d要補(bǔ)球，使鋼球級(jí)配變得非常混亂。運(yùn)轉(zhuǎn)時(shí)間越長(zhǎng)，鋼球級(jí)數(shù)越多，球磨機(jī)鋼球的級(jí)配情況很難計(jì)算。小型磨機(jī)清倉(cāng)時(shí)，可算好配比，把球按尺寸分類(lèi)后填加，級(jí)配的數(shù)量與計(jì)算的基本相符。大型磨機(jī)，由于鋼球數(shù)量太大，球磨機(jī)鋼球分類(lèi)太費(fèi)時(shí)，給生產(chǎn)安排造成困難。 </p> <p> 大多數(shù)廠家都不采用此法，而是按各自的要求，將爛球、鐵渣及小球揀出，加完后與標(biāo)準(zhǔn)填加量比較，缺少的量，一般是加入大級(jí)鋼球，或憑經(jīng)驗(yàn)加入一些其它的鋼球。鋼球的級(jí)配及平均球徑是估算的，很不準(zhǔn)確。鋼球與材質(zhì)中合金元素也有著非常重要的關(guān)系。浙江原裝鋼球廠家供應(yīng)</p><p
