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>

高鉻球的含鉻量是大于等于10.0%。含碳量在1.80%和3.20%之間。根據(jù)國(guó)家標(biāo)準(zhǔn),高鉻球硬度必須不小于58hrc,沖擊值應(yīng)大于等于3.0j/cm2。若達(dá)此硬度高鉻球必須用高溫淬火和回火處理。目前國(guó)內(nèi)高鉻球淬火有兩種方法包括油淬火和風(fēng)力淬火。如果高鉻球測(cè)試硬度低于54HRC，就意味著它沒(méi)有經(jīng)過(guò)淬火處理。 </p> <p> <br /> </p> <p> 中鉻球質(zhì)量指標(biāo) </p> <p> <br /> </p> <p> 中鉻球規(guī)定含鉻量范圍從3.0%到7.0%,含碳量在1.80%和3.20%之間。它的沖擊值應(yīng)不小于2.0j/cm2。國(guó)家標(biāo)準(zhǔn)要求中鉻球硬度應(yīng)該大于等于47hrc。為確保質(zhì)量,中鉻球應(yīng)經(jīng)高溫回火處理消除鑄造應(yīng)力。 </p><p> 鋼球感應(yīng)加熱可分為三類(lèi)： </p> <p> 高頻加熱：常用頻率為（200～300）KHZ，淬硬層深度為（0.5～2.5）mm。 </p> <p> 中頻加熱：常用頻率為（2500～8000）HZ，淬硬層深度為（2～10）mm。 </p> <p> <br /> </p> <p> 工頻加熱：電流頻率為50HZ，不需要頻設(shè)備，城市用交流電即可，硬層深度為（10～20）mm以上，城市用交流電即。 </p> <p> 鋼球感應(yīng)加熱優(yōu)缺點(diǎn)：感應(yīng)加熱表面淬火加熱速度快，生產(chǎn)率高，加熱溫度和淬硬層深度容易控制，鋼球表面氧化和脫碳少，鋼球變形小，可以使全部淬火過(guò)程實(shí)現(xiàn)機(jī)械化、自動(dòng)化。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。</p><div

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*難以切削加工，且在以后淬火過(guò)程中也容易變形和開(kāi)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(kāi)裂小。鋼球的分類(lèi)可以按照材質(zhì)、牌號(hào)、尺寸和用途等幾個(gè)方面分類(lèi)。上海專(zhuān)業(yè)鋼球***的選擇</p><p

在日本東京，一軸承鋼球被授予**小的商用鋼球軸承的吉尼斯世界紀(jì)錄稱(chēng)號(hào)，經(jīng)來(lái)自吉尼斯世界紀(jì)錄有限公司的**認(rèn)證其鋼珠的外直徑*為1.4978毫米。生產(chǎn)該鋼球的公司一直試圖證明其有著生產(chǎn)**小的量產(chǎn)軸承的能力。在2009年，它成功地打破了2mm的鋼球軸承的障礙，也為這個(gè)超小型球軸承鋪平道路。這一創(chuàng)紀(jì)錄的軸承的尺寸是1.5毫米外徑，0.5毫米內(nèi)徑，并在寬0.65毫米的長(zhǎng)度內(nèi)有六個(gè)鋼球。它的緊湊性，精度符合JIS碼。小山郁子在輕井澤工廠說(shuō)：“鋼球軸承的1.5毫米外徑能夠破紀(jì)錄要感謝我們團(tuán)隊(duì)的整個(gè)生產(chǎn)過(guò)程中的努力，我真的很高興，軸承，它們往往被忽視。我們大膽嘗試制造小型化軸承尺寸，并能推向市場(chǎng)。它讓我意識(shí)到，功夫不負(fù)有心人，并沒(méi)有什么是無(wú)法實(shí)現(xiàn)的?！?</p>
