在一些特殊條件下，常常需要特殊材質(zhì)的鋼球，來完成不同環(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)過一段時(shí)間運(yùn)轉(zhuǎn)，每7～10d要補(bǔ)球，使鋼球級配變得非常混亂。運(yùn)轉(zhuǎn)時(shí)間越長，鋼球級數(shù)越多，球磨機(jī)鋼球的級配情況很難計(jì)算。小型磨機(jī)清倉時(shí)，可算好配比，把球按尺寸分類后填加，級配的數(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，江蘇**鋼球在線咨詢、鐵渣及小球揀出，加完后與標(biāo)準(zhǔn)填加量比較，缺少的量，江蘇**鋼球在線咨詢，一般是加入大級鋼球，江蘇**鋼球在線咨詢，或憑經(jīng)驗(yàn)加入一些其它的鋼球。鋼球的級配及平均球徑是估算的，很不準(zhǔn)確。鋼球表面的檢測可以用渦輪探傷機(jī)器檢測。江蘇**鋼球在線咨詢</p><div

鋼球開裂原因分析：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，加工工藝過程如下：φ6.0mm熱軋盤圓（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300萬粒，用戶在使用過程中發(fā)現(xiàn)約60粒開裂成兩半，要求對鋼球發(fā)生開裂的原因進(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，斷口的微觀形貌見圖2～圖5。采用EDS7582能譜儀對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。江蘇**鋼球在線咨詢鋼球外觀檢測是鋼球加工過程中不可缺少的過程。</p><div

化學(xué)成分不銹鋼的耐蝕性隨含碳量的增加而降低，因此，大多數(shù)不銹鋼的含碳量均較低，***大不超過1.2%，有些鋼的Wc（含碳量）甚至低于0.03%（如00Cr12）。不銹鋼中的主要合金元素是Cr（鉻），只有當(dāng)Cr含量達(dá)到一定值時(shí)，鋼才有耐蝕性。因此，不銹鋼一般Cr（鉻）含量至少為10.5%。不銹鋼中還含有Ni、Ti、Mn、N、Nb、Mo、Si、Cu等元素用途不銹鋼不易產(chǎn)生腐蝕、點(diǎn)蝕、銹蝕或磨損。不銹鋼還是建筑用金屬材料中強(qiáng)度***高的材料之一。 </p> <p> 由于不銹鋼具有良好的耐腐蝕性，所以它能使結(jié)構(gòu)部件長久地保持工程設(shè)計(jì)的完整性。含鉻不銹鋼還集機(jī)械強(qiáng)度和高延伸性于一身，易于部件的加工制造，可滿足建筑師和結(jié)構(gòu)設(shè)計(jì)人員的需要。 </p><p style="text-indent:25px">鋼球是球軸承中承載載荷的滾動(dòng)體，是球軸承中**重要的零件之一，其加工過程相當(dāng)復(fù)雜，從冷鐓（或熱軋、鍛）球坯到的清洗包裝，設(shè)及到諸多的加工工序，而每道加工工序都會(huì)對球的內(nèi)在和表面質(zhì)量產(chǎn)生較大的影響。鋼球的制造質(zhì)量會(huì)直接影響到軸承的使用壽命，因而是極其重要的[1]。鋼球因材料冶金缺點(diǎn)導(dǎo)致軸承失效的案例屢見不鮮，分析難度也不大，但對于小尺寸鋼球開裂，尤其是內(nèi)在冶金缺點(diǎn)導(dǎo)致的開裂，由于難于通過熱酸洗定位材料軋制方向，故分析難度就會(huì)增大。本文采用金相、硬度檢測、宏觀及微觀觀察分析的方法，廣開思路，對鋼球產(chǎn)生開裂的原因進(jìn)行了分析。常州飛鴿鋼球歡迎大家前來咨詢！</p><div

style="text-indent:25px">316和317不銹鋼（317不銹鋼的性能見后）是含鉬不銹鋼種。317不銹鋼中的鉬含量略高明于316不銹鋼.由于鋼中鉬，該鋼種總的性能優(yōu)于310和304不銹鋼，高溫條件下，當(dāng)腐蝕品的濃度低于15％和高于85％時(shí)，316不銹鋼具有較廣的用途。316不銹鋼還具有良好的而氯化物侵蝕的性能，所以通常用于海洋環(huán)境。316L不銹鋼的比較大碳含量0.03,可用于焊接后不能進(jìn)行退火和需要比較大耐腐蝕性的用途中。耐腐蝕性：耐腐蝕性能優(yōu)于304不銹鋼，在漿和造紙的生產(chǎn)過程中具有良好的耐腐蝕的性能。而且316不銹鋼還耐海洋和侵蝕性工業(yè)大氣的侵蝕。鋼球的表面質(zhì)量檢測非常重要。江蘇**鋼球在線咨詢</p><p

G20， G24……G100， G500， G1000等。例如，一個(gè)鋼球的級別是G10，那么意味著鋼球的直徑變動(dòng)量是0.25μm或者更小，圓度是0.25μm, 粗糙度是0.25μm，公差范圍在+/-9μm。由此可知，一個(gè)鋼球達(dá)到G10級，證明鋼球的各項(xiàng)參數(shù)均符合G10所涵括的范圍。 </p> <p>
