當真空感應熔煉爐爐內狀(zhuang)態發生變化時，可能會(hui)出現實踐(jian)溫(wen)度(du)與設(she)定值相(xiang)違背，這時可經過溫(wen)度(du)操控(kong)儀中的自整定功能來糾正其違背量，使其升(sheng)溫(wen)嚴(yan)格(ge)依照設(she)定曲線進行。加熱(re)元件是(shi)加熱(re)電(dian)源的負載，其資料(liao)選用高(gao)溫(wen)鉬(mu)帶，可長(chang)時間作業于高(gao)溫(wen)狀(zhuang)態下。加熱(re)元件的阻(zu)值要與磁(ci)性調壓(ya)器相(xiang)匹配，不(bu)然會(hui)出現溫(wen)度(du)升(sheng)不(bu)上去或磁(ci)調溫(wen)升(sheng)較高(gao)。加熱(re)電(dian)源主電(dian)路為三相(xiang)交流電(dian)源，由交流接(jie)觸器操控(kong)，操控(kong)電(dian)路由溫(wen)控(kong)儀操控(kong)。
