將奧氏體化鋼球加熱到320°C并在硝酸鉀的鹽浴中，等溫保持足夠長的時間，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，上海鋼球標(biāo)準(zhǔn)，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裂傾向，上海鋼球標(biāo)準(zhǔn)，上海鋼球標(biāo)準(zhǔn)。

眾所周知，耐磨鋼球按生產(chǎn)工藝的不同，分為熱軋鋼球、鍛造鋼球和鑄造鋼球，應(yīng)用于不同的領(lǐng)域，各種耐磨鋼球各有其特點(diǎn)，像熱軋鋼球特別適用于冶金礦山等濕磨領(lǐng)域，而鑄造鋼球則適用于水泥、建材等干磨領(lǐng)域。 </p> <p> 熱軋鋼球源于前蘇聯(lián)，1956年，邯鋼引進(jìn)國內(nèi)熱軋鋼球生產(chǎn)線，隨著熱軋鋼球原材料的不斷研發(fā)以及生產(chǎn)設(shè)備的不斷改進(jìn)，熱軋鋼球在國際國內(nèi)礦山行業(yè)應(yīng)用均取得了良好效果。 </p> <p> 熱軋鋼球的生產(chǎn)工藝流程如下： </p> <p> 圓鋼棒料入廠檢驗(yàn)； </p> <p>

</p> <p> 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：用人工目測檢查鋼球表面有無任何瑕疵，并用千分尺測量真圓度，批直徑變動量及用表面粗糙度儀檢測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。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海鋼球標(biāo)準(zhǔn)"
