回火目的：減少或消除淬火應(yīng)力，提高韌性和塑性，獲得硬度、強(qiáng)度，山東原裝鋼球質(zhì)量放心可靠、塑性和韌性的適當(dāng)配合，以滿足鋼球的性能要求。 </p> <p> 碳鋼的回火特性： </p> <p> 淬火鋼回火后的力學(xué)性能，常以硬度來衡量。在未完全淬透情況下，沿工件截面硬度差別隨著回火溫度的提高及回火時(shí)間的延長(zhǎng)而逐漸減?。辖痄摰幕鼗鹛匦裕綎|原裝鋼球質(zhì)量放心可靠，基本和碳鋼類似。但對(duì)具有二次硬化現(xiàn)象的鋼則不同，山東原裝鋼球質(zhì)量放心可靠，也不能簡(jiǎn)單地用M參數(shù)來表征回火程度。鋼球的表面光潔度及抗腐蝕能力等技術(shù)指標(biāo)都嚴(yán)重影響了鋼球的質(zhì)量，從而影響軸承的質(zhì)量的使用壽命。山東原裝鋼球質(zhì)量放心可靠</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(duì)鋼球發(fā)生開裂的原因進(jìn)行分析。

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(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。山東原裝鋼球質(zhì)量放心可靠高等級(jí)的鋼球要求表面光亮，無壞球。</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。</p><p style="text-indent:25px">在1600度以下的間斷使用和在1700度以下的連續(xù)使用中，316不銹鋼具有好的耐氧化性能。在800-1575度的范圍內(nèi)，比較好不要連續(xù)作用316不銹鋼，但在該溫度范圍以外連續(xù)使用316不銹鋼時(shí)，該不銹鋼具有良好的耐熱性。316L不銹鋼的耐碳化物析出的性能比316不銹鋼更好，可用上述溫度范圍。熱處理：在1850-2050度的溫度范圍內(nèi)進(jìn)行退火，然后迅速退火，然后迅速冷卻。316不銹鋼不能過熱處理進(jìn)行硬化。焊接：316不銹鋼具有良好的焊接性能。可采用所有標(biāo)準(zhǔn)的焊接方法進(jìn)行焊接。焊接時(shí)可根據(jù)用途，分別采用316Cb、316L或309Cb不銹鋼填料棒或焊條進(jìn)行焊接。為獲得比較好的耐腐蝕性能，316不銹鋼鋼的焊接斷面需要進(jìn)行焊后退火處理。如果使用316L不銹鋼，不需要進(jìn)行焊后退火處理。典型用途：紙漿和造紙用設(shè)備熱交換器、染色設(shè)備、膠片沖洗設(shè)備、管道、沿海區(qū)域建筑物外部用材料。鋼球根據(jù)生產(chǎn)加工工藝分為研磨鋼球，鍛造鋼球，鑄造鋼球。</p><div

鑄造鋼球因材料以及加工工藝的不同，熱處理內(nèi)外淬透性差，生產(chǎn)處理鋼球內(nèi)外硬度差別大。 </p> <p> 因?yàn)殄懺熹撹F有高碳錳鉻等合金元素合理搭配，生產(chǎn)熱處理內(nèi)外淬透性強(qiáng)，內(nèi)外硬度差別小，還因沖擊值的差別。因此決定鍛球與鑄造球相比更加不破碎。 </p> <p> 鍛造鋼球破碎率小，而鑄造鋼球破碎率大，一般情況鑄造鋼球破碎率在3%，而鍛造鋼球在1%，由于破碎率小，增加了磨機(jī)的出粉率，并減少了選礦成本，就提高了磨機(jī)生產(chǎn)效率。 </p> <p> 由于我們的鍛造鋼球金相組織是細(xì)針狀馬氏體組織，硬度較高，與鑄造鋼球同等耐磨性能下，鍛造鋼球價(jià)格遠(yuǎn)遠(yuǎn)低于鑄造鋼球，研磨成本更低。鋼球生產(chǎn)方式一般有鍛造、軋制、半固態(tài)成型及鑄造四大類。山東原裝鋼球質(zhì)量放心可靠</p><p

不銹鋼珠應(yīng)用：鋼珠金屬磨料的一種，主要品種有不銹鋼丸、鑄鋼丸、鋁丸、鋼絲切丸、研磨丸、銅丸，鋼珠廣泛應(yīng)用于有色金屬壓鑄件、澆鑄件，鋁型材、汽車零部件、機(jī)械制造業(yè)、五金、泵閥行業(yè)的表面處理。主要集中于去產(chǎn)品表面氧化皮、邊緣表面毛刺、表面粗糙化、亞光郊果、平整強(qiáng)化、除銹處理。 </p> <p> 鋼珠：鋼珠主要用于高要求高亮度的鋁合金，不銹鋼等產(chǎn)品拋光。鋼珠分不銹鋼和研磨碳鋼兩種，不銹鋼鋼珠使用很方便，無須防銹，碳鋼鋼珠許要防銹！ </p> <p> 應(yīng)用領(lǐng)域：不銹鋼拋光球通常用于各種五金件的去毛疵及拋光，從而使工件達(dá)到光滑光亮的效果：銅件、鋁件、銀器等等。另外鋼球也可以用來研磨藥材、化工原料。 </p> <p> 特性：任何一種鋼球均可用來拋光，但具體選用哪種材料哪種規(guī)格要根據(jù)工件的尺寸、形狀及性能來確定，通常拋光球選用4MM不銹鋼球。山東原裝鋼球質(zhì)量放心可靠</p><p
