</p> <p> 定義：是采用一定方法使工件表面產(chǎn)生一定頻率的感應(yīng)電流，將零件表面迅速加熱，然后迅速淬火冷卻的一種熱處理操作方法。 </p> <p> 原理：如圖所示，電磁感應(yīng)產(chǎn)生同頻率的感應(yīng)電流即渦流。渦流在工件截面上的分布是不均勻的，心部幾乎等于零，上海庫存鋼球服務(wù)放心可靠，上海庫存鋼球服務(wù)放心可靠，而表面電流密度極大，稱為“集膚效應(yīng)”，頻率愈高，電流密度極大的表面層愈薄。依靠這種電流和工件本身的電阻，使工件表面迅速加熱到淬火溫度，而心部溫度仍接近室溫，然后立即噴水冷卻，上海庫存鋼球服務(wù)放心可靠，使工件表面淬硬。鋼球的等級有G3，G5，G10，G100，G200，G500，G700，G1000等等。上海庫存鋼球服務(wù)放心可靠</p><div

不銹鋼球440/440C：性能：硬度達(dá)到56—58度，有磁性，耐腐蝕性好，耐磨性和韌性強(qiáng)用途：主要應(yīng)用于軸承、沖壓/液壓件、閥門、密封件制冷設(shè)備、航空航天高精度的機(jī)械件，工藝品、玩具。 </p> <p> <br /> </p> <p>
