光球（Flashing）：去除球坯表面的環(huán)帶，同時(shí)提高鋼球表面的粗糙度，使球坯初步成球形。 </p> <p> 熱處理（Heat treatment）：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。有些廠家使用先進(jìn)的網(wǎng)帶熱處理流水線，通過各類儀表對(duì)淬火回火的時(shí)間和溫度的工藝參數(shù)進(jìn)行有效控制，確保產(chǎn)品質(zhì)量的穩(wěn)定性和可控性。 </p><p> 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(guó)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(guó)際國(guó)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> 配料進(jìn)入連續(xù)式加熱爐加熱 </p> <p> 紅熱態(tài)的鋼坯進(jìn)入鋼球軋機(jī)軋制成鋼球， </p> <p> 紅熱態(tài)鋼球進(jìn)入特殊設(shè)計(jì)在線熱處理設(shè)備進(jìn)行淬火—回火熱處理鋼球的材質(zhì)有很多種，常規(guī)的是鉻鋼球、不銹鋼球，碳鋼球等。</p><div

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>
