供應大噸位調質線通電運行步驟：1、打開氮化爐總控電源。2、電柜控制面板上“手動/自動” 旋鈕，打到自動。3、進入控制系統觸摸屏，點擊“（一）打弧參數設定”，選擇開保溫段數09，完畢退出。4、大噸位調質線生產點擊“（二）升溫保溫參數設定”，查看參數是否正確，9保溫時間300min，點擊“升壓保壓參數設定”，5到達壓力350Pa。5、進入系統運行，選擇確認爐體， 1號爐（左），2號爐（右），若爐體不是要工作爐體，點擊“爐體切換”，（爐體工作過程中一定不要按爐體切換按鈕）。6、上海大噸位調質線抽真空(kong)(kong)(kong)(kong)(kong)：左上角(jiao)系(xi)統開(kai)(kai)始(shi)按鈕(niu)(niu)由紅色變(bian)成綠(lv)色，真空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)1（3），2（4）按鈕(niu)(niu)變(bian)綠(lv)，檢查兩個(ge)真空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)是(shi)否(fou)都啟(qi)動(dong)(dong)運轉,如有不運轉，打(da)開(kai)(kai)電(dian)控(kong)(kong)(kong)柜右(you)(you)下門，檢查是(shi)否(fou)跳(tiao)閘，確認(ren)兩個(ge)真空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)都已啟(qi)動(dong)(dong)工作(zuo)(zuo)后(hou)(hou)，打(da)開(kai)(kai)真空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)蝶(die)(die)閥(fa)(fa)（之(zhi)前一(yi)定要關(guan)閉否(fou)則真空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)中油會(hui)被氣(qi)(qi)壓(ya)(ya)(ya)(ya)壓(ya)(ya)(ya)(ya)進爐(lu)(lu)(lu)體），開(kai)(kai)始(shi)抽真空(kong)(kong)(kong)(kong)(kong)，當(dang)壓(ya)(ya)(ya)(ya)強(qiang)達到(dao)(dao)(dao)(dao)100Pa左右(you)(you)時(shi)，關(guan)閉1（3）號真空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)蝶(die)(die)閥(fa)(fa)，當(dang)壓(ya)(ya)(ya)(ya)強(qiang)達到(dao)(dao)(dao)(dao)60Pa左右(you)(you)時(shi)，真空(kong)(kong)(kong)(kong)(kong)泵(beng)(beng)(beng)1（3）自(zi)動(dong)(dong)關(guan)閉（綠(lv)燈熄滅(mie)），高壓(ya)(ya)(ya)(ya)按鈕(niu)(niu)自(zi)動(dong)(dong)開(kai)(kai)啟(qi)。7、黑(hei)色脈沖控(kong)(kong)(kong)制盤上，電(dian)壓(ya)(ya)(ya)(ya)撥鈕(niu)(niu)打(da)到(dao)(dao)(dao)(dao)左邊(bian)(bian)自(zi)動(dong)(dong)撥鈕(niu)(niu)，占空(kong)(kong)(kong)(kong)(kong)比撥鈕(niu)(niu)打(da)到(dao)(dao)(dao)(dao)右(you)(you)邊(bian)(bian)自(zi)動(dong)(dong)（自(zi)動(dong)(dong)時(shi)升(sheng)溫(wen)時(shi)間長，根據(ju)實際情況(kuang)可(ke)調為(wei)手動(dong)(dong)控(kong)(kong)(kong)制），電(dian)壓(ya)(ya)(ya)(ya)旋鈕(niu)(niu)，占空(kong)(kong)(kong)(kong)(kong)比旋鈕(niu)(niu)旋轉到(dao)(dao)(dao)(dao)右(you)(you)邊(bian)(bian)合適位置(zhi)（峰值電(dian)流(liu)=100~200 ，電(dian)流(liu)A≤150），爐(lu)(lu)(lu)體開(kai)(kai)始(shi)安全工作(zuo)(zuo)，罐內(nei)工件(jian)開(kai)(kai)始(shi)打(da)弧。8、滅(mie)弧送氨(an)氣(qi)(qi)爐(lu)(lu)(lu)內(nei)溫(wen)度(du)(du)到(dao)(dao)(dao)(dao)90度(du)(du)，爐(lu)(lu)(lu)罐內(nei)輝光穩定之(zhi)后(hou)(hou)（不閃弧），開(kai)(kai)氨(an)氣(qi)(qi)罐，黃色換向(xiang)閥(fa)(fa)打(da)到(dao)(dao)(dao)(dao)左邊(bian)(bian)1號爐(lu)(lu)(lu)（右(you)(you)邊(bian)(bian)為(wei)2號爐(lu)(lu)(lu)），氨(an)氣(qi)(qi)流(liu)量不用(yong)調，控(kong)(kong)(kong)制器(qi)會(hui)根據(ju)爐(lu)(lu)(lu)內(nei)壓(ya)(ya)(ya)(ya)強(qiang)自(zi)動(dong)(dong)調整。9、加送二氧化(hua)碳氣(qi)(qi)體大(da)約(yue)9-10小時(shi)后(hou)(hou)升(sheng)溫(wen)到(dao)(dao)(dao)(dao)500℃時(shi)占空(kong)(kong)(kong)(kong)(kong)比撥鈕(niu)(niu)打(da)至自(zi)動(dong)(dong)狀(zhuang)態，然后(hou)(hou)繼續(xu)升(sheng)溫(wen)至510℃到(dao)(dao)(dao)(dao)保溫(wen)狀(zhuang)態，打(da)開(kai)(kai)二氧化(hua)碳氣(qi)(qi)閥(fa)(fa)，設置(zhi)屏幕上2種氣(qi)(qi)體流(liu)量比例（比例約(yue)為(wei)7%）。
