class="box"><p><p> 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。根據(jù)加工材料分為軸承鋼球，不銹鋼球，碳鋼球，銅軸承鋼球，合金球等。 </p> <p> <br /> </p> <p> 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。由于歷史沿習(xí)及選礦工業(yè)一些特殊的使用條件和綜合環(huán)境、背景，在這些行業(yè)中，鍛造與軋制球占有相當(dāng)大的比例。半固態(tài)成型則具有非常規(guī)鑄造，安徽批發(fā)鋼球，非簡(jiǎn)單壓鑄所能解釋清的特點(diǎn)，以一種似鑄、似鍛，鑄鍛優(yōu)點(diǎn)兼而有之的先進(jìn)技術(shù)所形成的優(yōu)異性能而引起人們的關(guān)注。而鑄造鋼球則以其簡(jiǎn)單，安徽批發(fā)鋼球、靈活、可靠的生產(chǎn)方式，易于實(shí)現(xiàn)低投資大規(guī)模生產(chǎn)的擴(kuò)張優(yōu)勢(shì)，尤其是當(dāng)**和工程師面對(duì)煉鋼爐運(yùn)用各種先進(jìn)工藝和合金成份設(shè)計(jì)，發(fā)揮無盡的想象力，去創(chuàng)造一個(gè)又一個(gè)更新穎、更先進(jìn)的品種，安徽批發(fā)鋼球，來滿足競(jìng)爭(zhēng)需要所帶來的成就感，更非常人所能體會(huì)。理所當(dāng)然的鑄球的高性價(jià)比與持續(xù)發(fā)展的潛力，使之成為當(dāng)今粉碎工業(yè)尤其是水泥粉碎工業(yè)鋼球生產(chǎn)方式中當(dāng)仁不讓的主力軍。 </p> <p> 怎么鍛造實(shí)心鋼球呢？材料為20號(hào)鋼，采用鍛造方法制造直徑為50MM的實(shí)心鋼球。所鍛造的鋼球表面要光滑，尺寸公差盡可能小，橢圓度小。可以用熱軋方式生產(chǎn)。鋼球可以用在指甲油里。安徽批發(fā)鋼球</p><div style="width:100%;text-align: center;"><img style="max-width:

伸線（拔絲）：將線材用拉絲機(jī)拉伸至所需要的線徑； </p> <p> 冷鐓（鍛壓）：將拉好的線材置入鋼球冷鐓機(jī)，由機(jī)內(nèi)的鋼模鐓打成球胚； </p> <p> 光球：光球機(jī)內(nèi)的兩塊鑄鐵磨球圓板將冷鐓球胚子加壓銼磨，去除球胚上的外環(huán)帶和兩極點(diǎn)； </p> <p> 軟球：軟球機(jī)內(nèi)的兩塊鑄鐵磨球圓板將光球球胚子銼磨使球胚子磨成所需球徑及表面粗糙度； </p> <p> 熱處理：將球裝入熱處理爐內(nèi)加以滲碳后淬火再回火使球具有一定的滲碳層及硬度，韌性和壓碎負(fù)荷； </p> <p> 硬磨：研磨機(jī)內(nèi)的砂輪圓板將熱處理球胚加壓磨削，以去除球表面的黑色氧化層及修正球的精度； </p> <p> 精研/拋光清洗：精研：將研磨球胚在精研機(jī)內(nèi)精研磨，使球達(dá)到成品所需要的精度和光潔度；拋光清洗：將球倒入拋光滾桶內(nèi)轉(zhuǎn)動(dòng)并用拋光清洗劑加水清洗使球面清潔光亮； </p> <p> 外觀選別：用人工目測(cè)檢查鋼球表面有無任何瑕疵，并用千分尺測(cè)量真圓度，批直徑變動(dòng)量及用表面粗糙度儀檢測(cè)表面粗糙度來作為終檢； </p> <p> 包裝：將鋼球/不銹鋼球/軸承鋼球涂上防銹油后裝入紙箱或編織袋后打包。 </p> <p> 出貨：在客戶有要求的前提下，要按照客戶要求進(jìn)行包裝出貨。浙江質(zhì)量鋼球性價(jià)比出眾按照材質(zhì)分類，鋼球可以分為：不銹鋼球、軸承鋼球和碳鋼球。</p><div style="width:100%;text-align: center;"><img

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。 </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(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> 耐磨鋼球另一種是用鋼廠產(chǎn)的圓鋼熱軋而成的鋼球，全過程自動(dòng)化控制，鋼球硬度均勻，心部硬度高，破碎率低，鋼球沖擊值大，第四種是用火車轱轆下料鍛打而成，這種鋼球成本低，但鋼球心部硬度低，易破碎，耐磨性能差。 </p> <p> 耐磨鋼球廣泛應(yīng)用于冶金礦山、水泥建材、火力發(fā)電、煙氣脫硫、磁性材料、化工、水煤漿、球團(tuán)礦、礦渣、超細(xì)粉、粉煤灰、碳酸鈣、石英砂等行業(yè)球磨機(jī)。全世界每年鋼球的消耗量在3000-5000萬噸，其中中國(guó)鋼球消耗量在300-500萬噸，是鋼球消耗大國(guó)。鋼球可以用在汽車剎車系統(tǒng)里。</p><div

鋼球設(shè)計(jì)流程： </p> <p> 鋼球球化退火（加熱到750°C）→保溫3小時(shí)→爐冷至600°C出爐空冷至室溫→將鋼球淬入320°C的硝酸鉀鹽浴中→保溫一段時(shí)間→取出空冷→將鋼球加熱到150°C-170°C回火→保溫3小時(shí)左右→取出油冷至室溫。 </p> <p> 球化退火：球化退火是使鋼球中碳化物球化而進(jìn)行的退火工藝。將鋼球加熱到750度，保溫一段時(shí)間，然后緩慢冷卻，得到在鐵素體基體上均勻分布的球狀或顆粒狀碳化物的組織。 </p> <p> <br /> </p> <p> 鋼球經(jīng)空冷所得組織是片層狀珠光體與網(wǎng)狀滲碳體，這種組織硬而脆，不僅難以切削加工，且在以后淬火過程中也容易變形和開裂。而經(jīng)球化退火得到的是球狀珠光體組織，其中的滲碳體呈球狀顆粒，彌散分布在鐵素體基體上，和片狀珠光體相比，不但硬度低，便于切削加工，而且在淬火加熱時(shí)，奧氏體晶粒不易長(zhǎng)大，冷卻時(shí)工件變形和開裂小。鋼球的標(biāo)準(zhǔn)有AISI52100、SUJ-2、100Cr6等等。安徽口碑好鋼球推薦企業(yè)</p><p
