　　（1）由于(yu)控(kong)制模(mo)式(shi)為三位控(kong)制（加(jia)熱(re)、保持和停止(zhi)），該控(kong)制模(mo)式(shi)溫(wen)(wen)度(du)控(kong)制波動(dong)大(da)，溫(wen)(wen)度(du)控(kong)制精度(du)差(cha)（±15度(du)），加(jia)熱(re)功率(lv)不(bu)可調，因此(ci)浪(lang)費能量，加(jia)熱(re)效率(lv)低(di)，其他繼電器的(de)觸點(dian)(dian)動(dong)作頻繁(fan)，因此(ci)觸點(dian)(dian)磨(mo)損嚴重(zhong)，故障率(lv)逐年上升，對生產構(gou)成(cheng)嚴重(zhong)威脅(xie)。

　　（2）退火(huo)爐在運行期間(jian)具(ju)有(you)高噪聲和(he)振動(dong)(dong)，接觸器機構很容易松(song)動(dong)(dong)，導致(zhi)連接處嚴(yan)重(zhong)發熱，容易引發火(huo)災事故和(he)其他電氣故障。

　　1、進(jin)線(xian)柜(ju)(ju)操(cao)作(zuo)(zuo)進(jin)線(xian)柜(ju)(ju)的操(cao)作(zuo)(zuo)包括(kuo)合閘(zha)和分(fen)閘(zha)操(cao)作(zuo)(zuo)，面板(ban)指(zhi)示包括(kuo)電(dian)壓指(zhi)示、正常工作(zuo)(zuo)電(dian)源指(zhi)示和空氣開關分(fen)離指(zhi)示。

　　2、爐門(men)(men)驅動控(kong)制(zhi)(zhi)系統爐門(men)(men)驅動系統執行前后(hou)爐門(men)(men)的增加操(cao)(cao)作，爐門(men)(men)控(kong)制(zhi)(zhi)系統為(wei)微(wei)動操(cao)(cao)作控(kong)制(zhi)(zhi)，電氣控(kong)制(zhi)(zhi)具有上限和下限以及增加聯鎖控(kong)制(zhi)(zhi)。

　　3、控(kong)制(zhi)(zhi)電(dian)源(yuan)系統的控(kong)制(zhi)(zhi)電(dian)源(yuan)主(zhu)要(yao)提供六區加熱(re)回路的控(kong)制(zhi)(zhi)電(dian)源(yuan)以及儀表(biao)和退(tui)火爐爐門的控(kong)制(zhi)(zhi)電(dian)源(yuan)，控(kong)制(zhi)(zhi)電(dian)源(yuan)的操作通過打開和關(guan)(guan)閉(bi)相關(guan)(guan)空氣斷(duan)路器和相關(guan)(guan)按(an)鈕(niu)來實現。

　　4、四區加熱回路操(cao)作(zuo)(zuo)四區加熱電(dian)路通過操(cao)作(zuo)(zuo)每(mei)個區的(de)(de)啟動(dong)和(he)(he)停止按(an)鈕，實(shi)現每(mei)個區的(de)(de)斷電(dian)和(he)(he)傳(chuan)輸操(cao)作(zuo)(zuo)。當電(dian)源關閉并(bing)傳(chuan)輸時，相(xiang)應(ying)的(de)(de)指示(shi)燈(deng)點(dian)亮，S型(xing)功率調節(jie)器(qi)開始根據am909-301-010-000編程輸出自(zi)動(dong)調節(jie)加熱功率。
