利用在(zai)電(dian)(dian)場作用下高速(su)(su)(su)運動的(de)電(dian)(dian)子(zi)轟擊物(wu)體表面，使之(zhi)被(bei)加(jia)(jia)熱(re)(re)。進行(xing)電(dian)(dian)子(zi)束加(jia)(jia)熱(re)(re)的(de)主要部件是電(dian)(dian)子(zi)束發生器，又稱電(dian)(dian)子(zi)。電(dian)(dian)子(zi)主要由(you)陰極(ji)(ji)、聚束極(ji)(ji)、陽極(ji)(ji)、電(dian)(dian)磁透鏡和偏轉線圈等(deng)部分組成。陽極(ji)(ji)接地，陰極(ji)(ji)接負高位，聚焦(jiao)束通常和陰極(ji)(ji)同(tong)電(dian)(dian)位，電(dian)(dian)熱(re)(re)管采購，陰極(ji)(ji)和陽極(ji)(ji)之(zhi)間(jian)形成加(jia)(jia)速(su)(su)(su)電(dian)(dian)場。由(you)陰極(ji)(ji)發射的(de)電(dian)(dian)子(zi)，在(zai)加(jia)(jia)速(su)(su)(su)電(dian)(dian)場作用下加(jia)(jia)速(su)(su)(su)到很高速(su)(su)(su)度，通過電(dian)(dian)磁透鏡聚焦(jiao)，電(dian)(dian)熱(re)(re)管廠(chang)家，再經偏轉線圈控(kong)制(zhi)，使電(dian)(dian)子(zi)束按一定的(de)方(fang)向射向被(bei)加(jia)(jia)熱(re)(re)物(wu)體。

電弧加熱

利用電(dian)(dian)弧(hu)(hu)(hu)產生的(de)高溫加熱物體(ti)。電(dian)(dian)弧(hu)(hu)(hu)是(shi)兩電(dian)(dian)極(ji)間(jian)(jian)的(de)氣(qi)體(ti)放電(dian)(dian)現象。電(dian)(dian)弧(hu)(hu)(hu)的(de)電(dian)(dian)壓不高但(dan)電(dian)(dian)流(liu)很大，其強大的(de)電(dian)(dian)流(liu)靠電(dian)(dian)極(ji)上蒸發的(de)大量(liang)離子所維持(chi)，因而電(dian)(dian)弧(hu)(hu)(hu)易受周(zhou)圍磁場的(de)影響(xiang)。當電(dian)(dian)極(ji)間(jian)(jian)形成電(dian)(dian)弧(hu)(hu)(hu)時(shi)，電(dian)(dian)弧(hu)(hu)(hu)柱(zhu)的(de)溫度可達3000～6000K，吉林電(dian)(dian)熱管，適于(yu)金(jin)屬的(de)高溫熔煉。

電(dian)(dian)弧(hu)(hu)加熱(re)(re)有(you)直(zhi)接和間接電(dian)(dian)弧(hu)(hu)加熱(re)(re)兩種(zhong)。直(zhi)接電(dian)(dian)弧(hu)(hu)加熱(re)(re)的(de)電(dian)(dian)弧(hu)(hu)電(dian)(dian)流直(zhi)接通(tong)過被加熱(re)(re)物體(ti)(ti)，電(dian)(dian)熱(re)(re)管(guan)報價，被加熱(re)(re)物體(ti)(ti)必須是電(dian)(dian)弧(hu)(hu)的(de)一(yi)個電(dian)(dian)極或是媒質。

目(mu)前國內所(suo)使用(yong)(yong)的(de)防爆加熱(re)(re)(re)器大部分是以電能(neng)為(wei)熱(re)(re)(re)源的(de)電加熱(re)(re)(re)設備(bei)，如浸入在導熱(re)(re)(re)油中的(de)管狀電熱(re)(re)(re)元(yuan)件通電產生熱(re)(re)(re)量。整體結構外形上緊(jin)湊、占地面積少、重量輕、使用(yong)(yong)方面更簡便。采用(yong)(yong)電加熱(re)(re)(re)更環保，不受(shou)外界(jie)的(de)氣候及壓力影響(xiang)。

當經過(guo)用熱(re)(re)(re)設(she)備卸(xie)載后，導熱(re)(re)(re)油重新通過(guo)循(xun)環泵，回到電加(jia)熱(re)(re)(re)爐再吸收熱(re)(re)(re)量傳輸給用熱(re)(re)(re)設(she)備，如此周(zhou)而(er)復始，實現熱(re)(re)(re)量的連(lian)續傳遞。
