起初，nm450耐磨鋼(gang)板等(deng)(deng)離(li)子(zi)加熱技(ji)(ji)術不(bu)盡如人意，主要(yao)表現(xian)在(zai)以(yi)下(xia)幾個(ge)方面(mian)：一是起弧(hu)困難(nan)；二是由于(yu)中間(jian)罐(guan)(guan)內鋼(gang)水液面(mian)不(bu)穩，等(deng)(deng)離(li)子(zi)弧(hu)難(nan)以(yi)維持而導致(zhi)滅火；三(san)是使用時噪音大；四是等(deng)(deng)離(li)子(zi)產(chan)(chan)生的(de)電磁輻(fu)射對周圍(wei)設(she)備(bei)的(de)弱(ruo)電系統(tong)產(chan)(chan)生影響(xiang)；五是加熱效(xiao)率較低(di)。隨著(zhu)連鑄技(ji)(ji)術的(de)發展(zhan)，這些不(bu)足(zu)逐(zhu)漸得到解決。目前，等(deng)(deng)離(li)子(zi)加熱技(ji)(ji)術重(zhong)新回到中間(jian)罐(guan)(guan)冶金技(ji)(ji)術的(de)舞(wu)臺。

　　等(deng)(deng)離(li)子(zi)(zi)加(jia)熱(re)(re)技術工作(zuo)原理(li)(li)。等(deng)(deng)離(li)子(zi)(zi)加(jia)熱(re)(re)裝置通(tong)過轉移弧(hu)(hu)方式將(jiang)電(dian)(dian)能(neng)(neng)轉換(huan)成(cheng)熱(re)(re)能(neng)(neng)。所(suo)謂轉移弧(hu)(hu)，就(jiu)是流經(jing)(jing)等(deng)(deng)離(li)子(zi)(zi)弧(hu)(hu)注(zhu)的(de)(de)電(dian)(dian)流必須經(jing)(jing)外部對象（鋼(gang)水）構成(cheng)回(hui)路。可上下移動的(de)(de)等(deng)(deng)離(li)子(zi)(zi)槍(qiang)(qiang)作(zuo)為陰極(ji)，被加(jia)熱(re)(re)的(de)(de)鋼(gang)水作(zuo)為陽極(ji)。工作(zuo)原理(li)(li)如下：運行開始時，將(jiang)等(deng)(deng)離(li)子(zi)(zi)槍(qiang)(qiang)下降到鋼(gang)液面附(fu)近，利用高頻電(dian)(dian)流起(qi)弧(hu)(hu)裝置在(zai)陰極(ji)和(he)陽極(ji)之間放(fang)電(dian)(dian)形成(cheng)電(dian)(dian)弧(hu)(hu)區。工作(zuo)氣體氬氣經(jing)(jing)等(deng)(deng)離(li)子(zi)(zi)槍(qiang)(qiang)吹入電(dian)(dian)弧(hu)(hu)區被電(dian)(dian)離(li)形成(cheng)等(deng)(deng)離(li)子(zi)(zi)弧(hu)(hu)注(zhu)，利用其電(dian)(dian)阻(zu)將(jiang)電(dian)(dian)能(neng)(neng)轉化為熱(re)(re)能(neng)(neng)。電(dian)(dian)離(li)度(du)越高，弧(hu)(hu)注(zhu)溫度(du)也越高。將(jiang)等(deng)(deng)離(li)子(zi)(zi)槍(qiang)(qiang)提升，拉長弧(hu)(hu)注(zhu)，增大了(le)弧(hu)(hu)注(zhu)的(de)(de)電(dian)(dian)壓，即提高了(le)等(deng)(deng)離(li)子(zi)(zi)槍(qiang)(qiang)的(de)(de)輸出功率，也就(jiu)是提高了(le)nm450耐(nai)磨鋼(gang)板鋼(gang)水的(de)(de)加(jia)熱(re)(re)功率。
